Great video Keith . Appreciate your time in making such an informative clip. We out in South Africa are starved for good wiring diagrams.Can you refer me to some sites that have wiring diagrams for European cars like the one that you used in this video.
Mervyn Naidu I am doing a little preliminary research and it seems that auto data offers the best wiring diagrams for your area. but I will continue to search
emanualonline dot com if you want "original" manuals and/or semi legal from the car maker or if you are diy just one car person: haynes.c o m/en-gb/car-manuals
Great video!! You have such a wealth of insight and knowledge, so glad Erick and Ivan talked you into doing videos. Your videos will definitely help a lot of people learning diagnostics.
i cant believe there were no voltage drop issues before this wire completely rotted away. you would think there had to have been. great video keith. love your procedures and how u track down problems man. u make it look easy and i certainly know it isnt.
Dylan Kinch I keep insisting that there had to be some type of an issue but the owner swears there was nothing . Either way fixed and I move along to the next one
Hey Keith, with all the "NEW" parts on the front of that engine it screams ACCIDENT to me. would not surprise me one bit if that wire was pinched in the process and never fixed or it was overlooked. Just saying
Even with a voltage drop which I believe would just mean a slower fan speed the ECM would just compensate by running it at a higher percentage? So unless you were sitting on a highway in traffic in high heat you may not have noticed anything.
Kevin Gallich I like the thought process , however even a higher percentage can not overcome the laws of electricity . Only x amount of current can get through y resistance with z amount of voltage supplied 😉
Not gonna lie. One of the best mechanics out there. A lot of people will not bother what you did and probably Will tell the owner to replace the fan 100 times. Much respect, thanks!
Another nice and quick video, I feel like I am finally internalizing the proper and optimal methods for diagnosing. Really appreciate the effort you put to get this videos online, really helps and encourage a lot of young techs like me to learn and become better
Car newbie here trying to get my older Mercedes going again. I really appreciate how you just walked me through this process step by step with the diagram and testing the lines. I don't have any type of computer and I'm trying to fix this on my own, but I can't believe how easy you made something so complicated seem. Thanks
Initially when I saw Mercedes cooling fan, I guessed fan control module, I've seen couple of them went south, and when I opened one of them, I saw exploded transistors, probably fan motor gets shorted inside and blows up transistors inside. Good diag video!
I really do appreciate the videos. I've always been intimidated on working on electrical issues, but now notice there is a procedure everyone follows to trace down faulty wires. It really helps a lot. Thanks for the vids.
Juan Hinojosa my motto is "they are just machines" . They don't have feelings and they don't try to intimidate. In the end all it comes down to is basics .
I am not an expert , BUT - if the car was running hot , you put in a thermostat , water pump and fan ? But you never check that the fan works - FIRST ? What if you ran jumper wires to it to see that it operates - why replace it ? Diagnosis VIA parts cannon ! Replace EVERYTHING - it's gotta work . We don't need no stinkin power ! How do they get away with it ?
I'm learning to hate Euro wiring diagrams. Why can't they just label stuff on the diagram, instead of the number/letter game? The last Volvo diagram I attempted to decipher had me ready to pull my hair out! Great vid Keith, and THANKS for posting it!
Thanks for another great video Keith You definitely have a gift for explaining, you would be a great teacher. I did like the long pause before the fan operated itself ;-) Please keep then coming
I can understand people calling on you for data com issues, but it's Unbelievable that a repair shop can't diagnose an open circuit on a power feed! ...Love your videos!
I forgot about all the corrosion seen on or in vehicles from the Northeast and upper Midwest states. I've lived in Southern California away from the coast, since 1976, but I do remember what the salt did to Massachusetts vehicles! Good diagnostic work!
Wow, that's some quality green crustiness. So very nice of it to show itself off so clearly and out in the open! Nice work sir. Thanks for taking the time to share this!
Great vid Keith. Bloody Benzes and Beamers look so intimidating, like working on an alien spaceship. Loved the PC with the pen marker, perfect for tutorials!!!
thanks for taking us along I appreciate the videos, I'm not a mechanic but I like to have a basis of knowledge when I talk to my mechanic... or at least know enough to be dangerous.
All of these comments are talking about the same thing but they don't realize it. What Eric, Ivan, and Keith have in common, which VERY FEW auto mechanics have is PASSION for their profession. When you bitch about parts changers and hacks and people that don't give a shit vs. these guys that's the difference. Are these guys motivated by money, of course they are, but they truly like what they do for a living. I was the some way with Semiconductor R&D and Manufacturing. I loved that shit. Did they pay me a lot of money to do what I loved to do anyway, YES. But making electrons do what I needed them to do is what I lived for. When you're just going to a job that's paying your bills you never put the effort into it that you do when you're doing something you love. The primary job of high school should be exposing students to as many different professions as possible so that a kid can pick the one he's going to do for the rest of his life and enjoy it. Instead they throw him out the door after graduation and hope that he finds something. Another failure of the American educational system.
SATAMAN Schmidt very well put as always. And I agree , teach them about the things they can use to have a successful career. I think you should do a live video about just this topic !
Thank you for making this video. Its not as complicated as I presume since I don't work on a lot of euro vehicles. keep up the good videos and explanations.
Fantastic explanation with the wiring diagram and circuit. I think it is wonderful to help us who's watching thank you for the videos and your time I try to compensate for your help trough paetron and hope a lot of people also do the same. For me, it is fantastic to learn the German cars been driving those all the time
I need to get my ac looked at. I been putting in the DIY freon from Walmart but it never gets cold. Fan works and it cycles but stays hot. You are very detailed in figuring out what is going on. Good job. Thumbs up and shared.
I will be up in NYC /Jersey area sometime this year. That would be great. I brought this 1998 Jeep Cherokee for 1200 bucks and have driven it for 4 years. I fix a little on it a time on it. #TeamNoCarNote. Have a good day.
I see you're using a test light, glad to see my 'Top 3' video helped 😀It'a Always Something Simple when it comes to electrical. Great video Keith, keep at it 👍🏼
when Paul Danner goes on a field call...laying on his back is the LAST thing he ever wants to do .. good job Keith.. you just straight ass climbed down there :)
It always takes so much longer to do anything when you decide to film it. Always trying for the shot so everyone can see what it is you are talking about. Thanks for taking the time and giving us all a front row seat.
Very cool. I have a similar issue on my 08 CLS. Shop wants $1100 to change the fan. Seems super high based on my research. I will investigate it more like you have shown.
Very informative. My CLK320 is doing the same thing so researching diagnostic procedures and appropriate fix. At least I know what the module looks like now and the prefuse! Back to the drawing board!
Despite our one hater channel, the comments below and the amount of views you've gained in a short time indicates to me your on the right track. It is a lot of work to bring us along, especially the time it take to edit. But from all of us, thank you! If my plan holds together and I can be an understudy for a day or two we need to make sure your real busy and complete 20 cars! (ha ha) I'll be the camera man and "key on" guy. That should help. See you soon. Oh, I almost forgot. I'll be away for the next 10 days with limited internet so I'll catch up when I get back.
Nice diagnostic lessons to be haved, last 42 yes dealers. and franchise's have been parts changers they would starve or close down but there is a plus gives real techs and honest ones like you guys and a like on YT work and demo your skills that are lacking in this industry which has been deemed rip off's and highway robbers, once a true tech along with mechanical skills costumers will be keepers rather than hopping garage to garage,, so those who call themselves Techs but really mechanics need to go back to school and learn how too proper diagnose these problems, thanks Keith for a wonderful lesson on how to be a true Tech and not just a mechanic, mechanics need to earn there badges by becoming a real Technician not by just a title that some mechanic call themselves, but authorized by those schools that provide such opportunities this is the future and cars are changing quicker than we can learn about diagnosing future problems we have no clue about as just being a mechanic ,and is my point, again good show Keith
jacob USA there are people I've seen out there that think that testing a solenoid is as simple as hearing it click, so I know the type you are referring to. What I can't understand is that with the wealth of ways to teach oneself nowadays that so many choose to use nonsensical methods in order to prove that they know something. I don't even teach a student that says the words "I know " more than once. The best way to learn is to admit that you don't know it all. On a bit of a ramble here ,but point is , take the good testing methods you see and apply them . There are some great guys doing great video like Eric , Ivan , Paul , Triangle, and so many others that each person should have a pen and pad handy at least to write down the titles of their videos and keep it near their toolboxes. I am glad you enjoyed my video and hope you'll like the others to come
New Level Auto in school one learns the basic and those want to pursue further education the automotive field take advantage what they can learn for free on YT yes eric paul Ivan keith Joe good source of fas diag, and in real time ,in school one gets basics once out in the field now there problems that where never duplicated in class because so many things can cause similar problems which may lead to the real problem source, automotive mech that have the basic now they need to get into the real world and finding a good work place that will apply training and begin an apprentiship, I started when 13 in 1972 today its has change 360 degrees we need to give them the chance to excell otherwise they loose interests and just have boxes collecting dust. BuT you guys make more fun even though frustrations at times , every car is a learning experience listen closely and ask questions when you don't now and this will show you're willing learn and then you will get help truly needed
Great video Keith and the explanation was clear enough that anyone should be able to follow along of what you are doing. I replied to your comment here because I see the same thing with new people at work that I train as new engineers right out of college. It still amazes me how management believes that someone with a degree is the almighty, supreme high intelligent being who knows all. And some of these guys don't even have any common sense and as you've mentioned, they pretty much know everything anyway. And what's more amazing is that there are some sharp guys on CZcams and the information is there, but people still like to just change parts and couldn't care less of how stuff works. I know it takes a lot of time doing the videos, but it will pay off in the end as I'm sure there's still a lot of folks out there who would like to learn the correct procedure of diagnosing and how systems work. Have a good weekend Keith and don't work too hard.
New level u couldn't have explained any direct than what you explained! Great tutorial. I on the other hand am a do first then explain. Not gifted in that area i suppose. However once i put hands on any of the jobs take from customers. They are all ways satified. Oh one other thing ..... A quick fix sometimes is as good or if not better than the right way. Find myself in that situation often. however i do warn the client about the temp fix and so on.. Keep up the good work Mech. Pro. Also when u located the problem there was no one to cheer u on. self satifaction! But i shared the joy with u! i know the feeling its as if God came down and touched u on the shoulder.And the moment that fan kicked over! Exciting! My GF doesn't see as exiciting. Up until i told her to take her benz the work shop! LOl!!! Keep at it my friend the Mech Pro Gods are their with you!
phil holbrook Hahaaa, yeah but still done in less than a half hour , and in between cuts finished a programming and found a parasitic draw using just a thermal camera
Thankyou so mutch for all your hard work to produce this video has really helped me get back on the road and get my autistic grand daughter to hospital apointments
your doing great keith considering the fast track enviroment you work in and limited time you have , at the point you spotted the green crusties i was so expecting a "well theres ya problem lady" , i guess thats what you get when youve watched alot of Erics vids , maybe you could drop it in on a future vid it will defo make a lot of people chuckle , great vid keep it up .
Thank you so much sir I put a brand new radiator and a brand new fan and module and my son 08CLS 63 AMG after it was real cold I was sitting in the parking lot at work and the radiator just blew coolant all over the place I told it home and have not been able to figure it out since the fan will just not work but this video is very helpful and tomorrow morning I will go out again and go under there and find the cable first I’ll find that power box and test it with my own meter that has power and I’m hoping that maybe something was ran over to and it’s a broken wireAnd it’s OK that I spent money on a plan and other things because I am learning thank you so much sir
Also I hear some other motor or fan running that is on the passenger side front corner behind a bumper I never heard this running before curious as to what it is
🙏🙏🙏🙏🙏 thank you very much for your support it really helped me out, I had a fan problem and because of you technical video show I found the same problem on my Mercedes. Thank you very much ( From Mozambique Ismael)
Great video thanks for Taking the time to do it, I have much the same problem with my S class w220, I think the control unit might be broken on mine .all the best from Scotland
Toyota and Honda ain't got nothin' on the M112 and M113 engines! Great engines! Sweet video Keith! I could've sworn it's the fan control unit(those go bad all the time) until I saw " open circuit ". Front end collision and things don't get fixed and put back in place=problems. Maybe I'm wrong,but it looked like that wire got partially cut from the impact and it might have worked until the green crusties set in...? That's a good car(except that it's a wagon. Lol),I really don't get why some hate on these. I had an E55 AMG,that thing was a monster! Loved it! Thanks for the video! 👍👍👍
Nick Nicu I want you to know I left the intro that way just for you pal lol. Yeah the motor is definitely rock solid on these. As for the collision I can guarantee you are correct
It's New York. Maybe they drove over a body and something caught on the harness. Nice video. Thanks. Between you and South Main Auto, I'm really learning how to use the test light.
Hope you continue to make videos. Time consuming yes but the value of the info is high to folks like me. Start a Patreon acct. I am a patron of ##### and #####, it's that valuable to me.
Glad that stuff didnt end up covered up. Good investigation skills by noticing stuff missing and looking there first saves time. Thanks for sharing your knowledge and I have a bmw to fix tommorow with a dash lit up like a christmas tree.
New Level Auto I figured it meant better open that wallet lol. Luckily this is a 735i and looks well taken care of so they should fix whatever it needs. Others that I see they want minimal repairs to get by.
Excelent video… I had similar issue twice in my C230. In my case was failure of the fun. Maybe because I live on a hot weather are in which summer 120 degrees is normal I assuming inside the Engine it should way higher makes the fan to fail. I seen at least one video in the net in which one person open the fan ( had to cut enclosure fix it and glue it back) and found cold solder on some capacitors that reflow of the solder fixed. I ask to keep the old fan so when I find time I will open it and double check if that is the case. But 100% correct if the fan don’t work the AC fail to work also. Thank you
New Level Auto got the GB reman injectors last week from rock auto gonna put them in next week! Funny thing is friend of mine has a truck one year older same exact symptoms replaced his injectors truck runs fine! You are the man !!!!!
Great Video! Its really sad how many so called technicians are out there who can't diagnose something as easy as no power at the fan module! Always gotta check your power and grounds before replacing a component even if its a known failure component because 1 out of 100 times you may find a broken wire!
Good Point! I forgot about that, in school they actually tricked everyone. put a resistor on the power wire and it light with a test lamp. most everyone said it lit the test light. a few said hey that test lamp is kind of dim. they were teaching us the value of using voltage drop to test for some problems. But most of the time i use a high impedance test lamp, and if i want to be sure of a good power and ground ill use a head lamp bulb.
Thanks for all the effort Keith, I really appreciate the extra time this takes you in such a fast paced environment you work, it's great to see a real master tech at work poetry in motion kudos to you sir!
The cable ties and tape didn't look factory, probably the insulation rubbed through and then the green crusties went to work on this one...Still impressive how such a thick cable got completely eaten. But overall I have to say that Benz looked in amazing condition for being a 2002. But the C-Class usually is pretty reliable (when you count out the early 350 V6s from the mid 2000s...they were garbage because of that balancer shaft gear defect). Good video, as an engineer it is always very interesting to see how products do in the field and how you can debug a system you have not designed yourself. Although I'm not in the automotive industry, it sometimes makes me rethink my decisions. Because if stuff comes back from the field with a fault, good debugging capabilities can be very valuable.
Great video Keith . Appreciate your time in making such an informative clip. We out in South Africa are starved for good wiring diagrams.Can you refer me to some sites that have wiring diagrams for European cars like the one that you used in this video.

Gregory Ellis glad you are enjoying them. Always feel a little funny making them , but I am glad to help anyone I can
@@NewLevelAuto where is your shop?I need some help..
Thanks Keith for taking the time posting this! Less than 15 minutes (including filming) and problem solved - you're the man!!

Great video Keith. You make diagnosing potentially puzzling issues simple by breaking it down into logical steps. Keep up the good work!
Very well done, Keith. Simple, straight forward and accurate diagnostics. I think twice about opening the hood on one of those turds.
Another nice and quick video, I feel like I am finally internalizing the proper and optimal methods for diagnosing.
Really appreciate the effort you put to get this videos online, really helps and encourage a lot of young techs like me to learn and become better
Thanks for posting Keith, appreciate you taking the trouble to bring us along.

German cars have never been good on electronics , failing fast .
Another great video from Keith, really like when show it all and there not edited to death I think viewers appreciate your time and effort A+
I really do appreciate the videos. I've always been intimidated on working on electrical issues, but now notice there is a procedure everyone follows to trace down faulty wires. It really helps a lot. Thanks for the vids.
Juan Hinojosa my motto is "they are just machines" . They don't have feelings and they don't try to intimidate. In the end all it comes down to is basics .
thank you for making videos. it's great to have thinkers and not parts swappers showing what they do.
Nice ! Keith, I like your style of diagnostics and vids. No drama, straight forward and plain common sense !
Billy R I kinda have to stick to that mindset with the number of cars needed per day. Thanks as always
You know Keith, it's all about the money ! Keep pumping them out ! Take Care !
I am not an expert , BUT - if the car was running hot , you put in a thermostat , water pump and fan ? But you never check that the fan works - FIRST ? What if you ran jumper wires to it to see that it operates - why replace it ? Diagnosis VIA parts cannon ! Replace EVERYTHING - it's gotta work . We don't need no stinkin power !

Thanks for another great video Keith
You definitely have a gift for explaining, you would be a great teacher.
I did like the long pause before the fan operated itself ;-)
Please keep then coming
been looking forward to your next vid. your putting out some great stuff Keith...even the famous Eric O is chiming in...
Javier Rocha thanks very much, and he is just keeping tabs on me so I don't surpass him 🤣(like that could ever happen)
I can understand people calling on you for data com issues, but it's Unbelievable that a repair shop can't diagnose an open circuit on a power feed! ...Love your videos!
I forgot about all the corrosion seen on or in vehicles from the Northeast and upper Midwest states. I've lived in Southern California away from the coast, since 1976, but I do remember what the salt did to Massachusetts vehicles! Good diagnostic work!
Awesome video. Glad I found you through SMA.
Thank you for your time in making these videos, it is very much appreciated
Wow, that's some quality green crustiness. So very nice of it to show itself off so clearly and out in the open! Nice work sir. Thanks for taking the time to share this!
Heck yeah that was a nice big puss sac!
Just ran into problems with green crusties on a wiring harness at work. it was an easy fix once I found it! nice work Keith!
Excellent class today Professor. Thanks for your effort. You do an excellent job of explaining things.
Rick S awesome , glad you liked it!
The green crusties man.... Every time! Great vid Keith, I don't think you stumbled around too much at all!
Great vid Keith. Bloody Benzes and Beamers look so intimidating, like working on an alien spaceship. Loved the PC with the pen marker, perfect for tutorials!!!
good video keith.... its like automotive classes at your fingertips
Great video. Surprised at clarity by using your phone. Short sweet and to the point and fixed. Nice!
thanks for taking us along I appreciate the videos, I'm not a mechanic but I like to have a basis of knowledge when I talk to my mechanic... or at least know enough to be dangerous.

Who'd have thought, crusties down there. Good methodical diagnosis !!
Tom OConnor Surprising that it didn't show some issues before the wire completely rotted away.
Kind of disappointing that the shop couldn't find that. Buts thats where you come in lol Good find
You have just made Benz diagnosis so easy right there brother. Bigs up!
Great video thanks for taking the time to capture some of your work it's much appreciated all the way to n.ireland
Thank you for making this video. Its not as complicated as I presume since I don't work on a lot of euro vehicles. keep up the good videos and explanations.
keep making the vids . one thing i have never been good at is auto electrical . im learning a lot between you and Eric thank you
Well done, Keith! If I didn't know better, I'd think you've been making vids for years. Thank you for sharing.
bill billl Thanks so much! Glad you like them
The Green Crusties strike again! Great Video! Thanks for taking the time to make them.
Fantastic explanation with the wiring diagram and circuit. I think it is wonderful to help us who's watching thank you for the videos and your time I try to compensate for your help trough paetron and hope a lot of people also do the same.
For me, it is fantastic to learn the German cars been driving those all the time
g johan it is really appreciated that you would contribute not only monetarily but also with your kind comments . Thank you again for your support
Love the video Keith! Keep making more. One hand wonder.
That red wire could be fix with soap and water. LOL 😁😁
I need to get my ac looked at. I been putting in the DIY freon from Walmart but it never gets cold. Fan works and it cycles but stays hot.
You are very detailed in figuring out what is going on. Good job.
Thumbs up and shared.
A VIEW IS A VIEW I can find you a decent shop in Atlanta who will take care of you . Better yet come on up to NYC and we will fix it together.
I will be up in NYC /Jersey area sometime this year. That would be great.
I brought this 1998 Jeep Cherokee for 1200 bucks and have driven it for 4 years. I fix a little on it a time on it. #TeamNoCarNote.
Have a good day.
I see you're using a test light, glad to see my 'Top 3' video helped 😀It'a Always Something Simple when it comes to electrical. Great video Keith, keep at it 👍🏼
The Homie Hektor never even knew what one was until I saw your video! Thanks 😉.....for stopping by
New Level Auto Ha! The knowledge is spreading 🙌🏼 Too funny 😂
Great Job Keith! You explained everything very well :)
One Auto, thanks Rob , I know it wasn't the most interesting but practicing on making these videos will get me there soon
You're doing a great job. It takes extra time out of your day to do these, and when your busy already it can be difficult 🍻(that's 2 beers)
Great vid! Love how you track it down!
Nice video Keith. May seem like simple problem solving to you but invaluable to us DIY'ers. I learn something with every video from you and Dr. O.
Legendary turning point phrase right here gentlemen: "And... I see red"
Why has it taken me this long to realise Keith has his own channel! now i have loads of catch up to watch! :))
when Paul Danner goes on a field call...laying on his back is the LAST thing he ever wants to do .. good job Keith.. you just straight ass climbed down there :)
+deepsquat600 like I tell my son . It's just dirt. At the end of the day we still have to fix a car. Thanks for watching and supporting
I'm glad you started making videos Keith. Definitely enjoy them!
Dylan we will definitely address this after class😉😁
Nice video, thanks for taking the time out of your day to educate us.
New subscriber here. I love the videos your making. You're very informative. Thanks to you and Eric O, I'm more confident on working on my cars.
Nice video. Easy to follow. Logical and fast. Thumbs up!
Sandbag1300 thanks for watching. We have to stick to simple sometimes in order to not lose track of our goals
It always takes so much longer to do anything when you decide to film it. Always trying for the shot so everyone can see what it is you are talking about. Thanks for taking the time and giving us all a front row seat.
man i have the same issue with A150 will try it tomorrow you are the best
great video as always from new level auto. keep em coming keith.
Very cool. I have a similar issue on my 08 CLS. Shop wants $1100 to change the fan. Seems super high based on my research. I will investigate it more like you have shown.

See you soon. Oh, I almost forgot. I'll be away for the next 10 days with limited internet so I'll catch up when I get back.
wyattoneable Absolutley looking forward to it ! As for the hater, well can't please everyone .
Nice diagnostic lessons to be haved, last 42 yes dealers. and franchise's have been parts changers they would starve or close down but there is a plus gives real techs and honest ones like you guys and a like on YT work and demo your skills that are lacking in this industry which has been deemed rip off's and highway robbers, once a true tech along with mechanical skills costumers will be keepers rather than hopping garage to garage,,
so those who call themselves Techs but really mechanics need to go back to school and learn how too proper diagnose these problems,
thanks Keith for a wonderful lesson on how to be a true Tech and not just a mechanic,
mechanics need to earn there badges by becoming a real Technician not by just a title that some mechanic call themselves,
but authorized by those schools that provide such opportunities this is the future
and cars are changing quicker than we can learn about diagnosing future problems
we have no clue about as just being a mechanic ,and is my point,
again good show Keith
jacob USA there are people I've seen out there that think that testing a solenoid is as simple as hearing it click, so I know the type you are referring to. What I can't understand is that with the wealth of ways to teach oneself nowadays that so many choose to use nonsensical methods in order to prove that they know something. I don't even teach a student that says the words "I know " more than once. The best way to learn is to admit that you don't know it all. On a bit of a ramble here ,but point is , take the good testing methods you see and apply them . There are some great guys doing great video like Eric , Ivan , Paul , Triangle, and so many others that each person should have a pen and pad handy at least to write down the titles of their videos and keep it near their toolboxes. I am glad you enjoyed my video and hope you'll like the others to come
New Level Auto
in school one learns the basic and those want to pursue further education the automotive field take advantage what they can learn for free on YT yes eric paul Ivan keith Joe good source of fas diag, and in real time ,in school one gets basics once out in the field now there problems that where never duplicated in class because so many things can cause similar problems which may lead to the real problem source,
automotive mech that have the basic now they need to get into the real world and finding a good work place that will apply training and begin an apprentiship, I started when 13 in 1972 today its has change 360 degrees we need to give them the chance to excell otherwise they loose interests and just have boxes collecting dust. BuT you guys make more fun even though frustrations at times ,
every car is a learning experience listen closely and ask questions when you don't now and this will show you're willing learn and then you will get help truly needed
Great video Keith and the explanation was clear enough that anyone should be able to follow along of what you are doing. I replied to your comment here because I see the same thing with new people at work that I train as new engineers right out of college. It still amazes me how management believes that someone with a degree is the almighty, supreme high intelligent being who knows all. And some of these guys don't even have any common sense and as you've mentioned, they pretty much know everything anyway. And what's more amazing is that there are some sharp guys on CZcams and the information is there, but people still like to just change parts and couldn't care less of how stuff works. I know it takes a lot of time doing the videos, but it will pay off in the end as I'm sure there's still a lot of folks out there who would like to learn the correct procedure of diagnosing and how systems work. Have a good weekend Keith and don't work too hard.
Awesome to see your doing videos now Keith! Keep up the good work!
+tankabbot22 many thanks for watching
New level u couldn't have explained any direct than what you explained! Great tutorial. I on the other hand am a do first then explain. Not gifted in that area i suppose. However once i put hands on any of the jobs take from customers. They are all ways satified. Oh one other thing ..... A quick fix sometimes is as good or if not better than the right way. Find myself in that situation often. however i do warn the client about the temp fix and so on.. Keep up the good work
Mech. Pro. Also when u located the problem there was no one to cheer u on. self satifaction! But i shared the joy with u! i know the feeling its as if God came down and touched u on the shoulder.And the moment that fan kicked over! Exciting! My GF doesn't see as exiciting. Up until i told her to take her benz the work shop! LOl!!! Keep at it my friend the Mech Pro Gods are their with you!
ahhh the minute man finally lasted 19:00 minutes good work!
phil holbrook Hahaaa, yeah but still done in less than a half hour , and in between cuts finished a programming and found a parasitic draw using just a thermal camera
Thankyou so mutch for all your hard work to produce this video has really helped me get back on the road and get my autistic grand daughter to hospital apointments
I enjoyed the video. Thanks for sharing and the extra time you put into making these videos.
Great, fast and efficient diagnosis. NOT like some guys who are beading it to dead !
I don't think I will ever own a Mercedes, but that doesn't matter. This type of troubleshooting applies to any car. Thanks
your doing great keith considering the fast track enviroment you work in and limited time you have , at the point you spotted the green crusties i was so expecting a "well theres ya problem lady" , i guess thats what you get when youve watched alot of Erics vids , maybe you could drop it in on a future vid it will defo make a lot of people chuckle , great vid keep it up .
chris90 had I not had the customer (Not shop owner) 15 feet away I could have had a lot more fun with this one . Thanks for watching
Somebody missed the basic electric class....
Great job like always Keith..
Thank you so much sir I put a brand new radiator and a brand new fan and module and my son 08CLS 63 AMG after it was real cold I was sitting in the parking lot at work and the radiator just blew coolant all over the place I told it home and have not been able to figure it out since the fan will just not work but this video is very helpful and tomorrow morning I will go out again and go under there and find the cable first I’ll find that power box and test it with my own meter that has power and I’m hoping that maybe something was ran over to and it’s a broken wireAnd it’s OK that I spent money on a plan and other things because I am learning thank you so much sir
Also I hear some other motor or fan running that is on the passenger side front corner behind a bumper I never heard this running before curious as to what it is
🙏🙏🙏🙏🙏 thank you very much for your support it really helped me out, I had a fan problem and because of you technical video show I found the same problem on my Mercedes. Thank you very much ( From Mozambique Ismael)
Great video thanks for Taking the time to do it, I have much the same problem with my S class w220, I think the control unit might be broken on mine .all the best from Scotland
Toyota and Honda ain't got nothin' on the M112 and M113 engines! Great engines! Sweet video Keith! I could've sworn it's the fan control unit(those go bad all the time) until I saw " open circuit ". Front end collision and things don't get fixed and put back in place=problems. Maybe I'm wrong,but it looked like that wire got partially cut from the impact and it might have worked until the green crusties set in...?
That's a good car(except that it's a wagon. Lol),I really don't get why some hate on these. I had an E55 AMG,that thing was a monster! Loved it!
Thanks for the video! 👍👍👍
Nick Nicu I want you to know I left the intro that way just for you pal lol. Yeah the motor is definitely rock solid on these. As for the collision I can guarantee you are correct
New Level Auto Lol!
Super informative video, thanks for taking the time to make it!
Great video Keith! we can tell how's the master .
It's New York. Maybe they drove over a body and something caught on the harness.
Nice video. Thanks. Between you and South Main Auto, I'm really learning how to use the test light.
Garth Goldberg glad to know they are helping people . Makes it all worthwhile. Thanks for the input
it's amazing how simple things are over looked.good work.
Great video, very well done with good audio and great content, thank you.
nice job. Your logical step by step process is explained well and easy to follow. Some quality crusties in that cable 👌
Badgertronix if you enjoyed it , then I am happy . Cheers!
Hope you continue to make videos. Time consuming yes but the value of the info is high to folks like me. Start a Patreon acct. I am a patron of ##### and #####, it's that valuable to me.
Steve Allen already done sir
Glad that stuff didnt end up covered up. Good investigation skills by noticing stuff missing and looking there first saves time. Thanks for sharing your knowledge and I have a bmw to fix tommorow with a dash lit up like a christmas tree.
Techman 48917 that's an option that they dont charge you for when you buy one 😁
New Level Auto I figured it meant better open that wallet lol. Luckily this is a 735i and looks well taken care of so they should fix whatever it needs. Others that I see they want minimal repairs to get by.
Excelent video…
I had similar issue twice in my C230. In my case was failure of the fun. Maybe because I live on a hot weather are in which summer 120 degrees is normal I assuming inside the Engine it should way higher makes the fan to fail. I seen at least one video in the net in which one person open the fan ( had to cut enclosure fix it and glue it back) and found cold solder on some capacitors that reflow of the solder fixed. I ask to keep the old fan so when I find time I will open it and double check if that is the case.
But 100% correct if the fan don’t work the AC fail to work also.
Thank you
Outstanding job, great work!!!!
Bigg T very much appreciated, thanks for stopping in and taking the time to comment
New Level Auto have a issue with my fan, does the 05 MBZ CL55 Amg have two modules if so where?
Thanks for sharing your knowledge and hard work.👍
Amazing sleuthing!! I'll be following your videos. Thanks!
nice to see a simple fix for this money pit......i mean mercedes benz!
Don't know yet if the fan or pcm is my issue because I need to do testing but, awesome video Man!!!! Please keep making worthwhile vids!!!
I wish you were my mechanic. With all the stupid issues on my W203, you'd most probably love working on it.
Nice work Keith thank you for making time to do this video !
DaveSender66 my pleasure as always. And again thanks for the support . Now how is my truck doing 😁
New Level Auto got the GB reman injectors last week from rock auto gonna put them in next week! Funny thing is friend of mine has a truck one year older same exact symptoms replaced his injectors truck runs fine!
You are the man !!!!!
Great Video! Its really sad how many so called technicians are out there who can't diagnose something as easy as no power at the fan module! Always gotta check your power and grounds before replacing a component even if its a known failure component because 1 out of 100 times you may find a broken wire!
daveyio87 keep in mind that it's also HOW you check the power. If you used a volt meter and 2 strands of wire were still good what would you read ?
in that case wouldn't there be some voltage only reduced due to higher resistance? Great vid. Thanks for your time and also the comments.
Good Point! I forgot about that, in school they actually tricked everyone. put a resistor on the power wire and it light with a test lamp. most everyone said it lit the test light. a few said hey that test lamp is kind of dim. they were teaching us the value of using voltage drop to test for some problems. But most of the time i use a high impedance test lamp, and if i want to be sure of a good power and ground ill use a head lamp bulb.
Great start to the video, I almost skipped it then realized I own a benz....
This is excellent. Thx for sharing. Keep em coming, please..
Thanks for all the effort Keith, I really appreciate the extra time this takes you in such a fast paced environment you work, it's great to see a real master tech at work poetry in motion kudos to you sir!
Du7cH 137 I really appreciate the compliment. It's comments like the ones I've been getting that make it all worthwhile
The cable ties and tape didn't look factory, probably the insulation rubbed through and then the green crusties went to work on this one...Still impressive how such a thick cable got completely eaten.
But overall I have to say that Benz looked in amazing condition for being a 2002. But the C-Class usually is pretty reliable (when you count out the early 350 V6s from the mid 2000s...they were garbage because of that balancer shaft gear defect).
Good video, as an engineer it is always very interesting to see how products do in the field and how you can debug a system you have not designed yourself. Although I'm not in the automotive industry, it sometimes makes me rethink my decisions. Because if stuff comes back from the field with a fault, good debugging capabilities can be very valuable.
Thanks for making the videos, i appreciate it, and learn from them.Cheers..
Great Video! You are the best! Thanks JP
Great job! Thanks for helping.
What a fantastic video. Thank you for making and posting.
