Probably my first comment on CZcams. But this video was worth it, because it saved me about 4000 SEK. Just hade to remove some leafs.
Great to hear my video helped you, many thanks :-)
Clear and informative as always - thank you Harvey for posting one more video! Fabia MK1 is really well made car, my (2003) so far had no bigger issues (except rear door leakage), but your channel keeps me informed and makes me prepared for lot of situations that could happen... We appreciate your work - keep filming :-).
Thank you for watching, I appreciate it a lot, glad you like them. Sadly fabi is kaput at the moment with immobilizor issue, but I will hopefully fix it soon :-)
We have teaser for your new video :-) !
I`m convinced that your Fabia is in best hands, so I`m sure that the issue will we solved soon.
Helpful hint(s) follow - I hope. Thanks for a very useful video explaining how to do this job. It's very tricky getting in there to remove the resistor pack (and I have small hands) - but I found it almost impossible to get the damn thing back in. Cold day, knock off to warm hands and think... so I removed the cable (make a note of the colour of the nearest wire), and found it very much easier to get the resistor pack back into place without the cable pressure. Cable back in (fine long nose pliers handy for this) and the job's done.
Helpful hint 2 - I was struggling to hold the glove compartment up whilst replacing the screws.. duh... empty the ton of junk out first ... sometimes we miss the obvious!
Well, this video was so helpful, I purchased a new resistor, I heard that the cheaper ones can catch fire so I got one direct from Germany. Put it in exactly as you described and now my fan works well. Scale of 1 to 10 of difficulty...2..it's a bit fidly but very easy to do. Many thanks once again.
Thanks, you're very welcome :-)
Thanks a mill again Harvey for your well documented and shot video - this is another job I was able to carry out myself thanks to you ! BTW my 05 vRS has not coughed or spluttered since I carried out the injector flush ! Keep these great no B.S. videos coming
Thanks Donal James, it means a lot that you like my stuff, bad cold at mo so struggling with vids, but will be up and running asap :-)
Great video. No excess chat, very clear well filmed
Thanks, glad to help :-)
Great video as aways, thanks mate for doing these videos, i love it. keep filming!
Thanks again Thomas, I'll try to keep it going as long as people enjoy them and I have a Fabi. If you have any suggestions for particular videos it would be greatly appreciated as are all your coms :-)
Brilliant, well put together and very informative again. Thanks
your very welcome and all appreciated. Thanks :-)
@@HatBoyHarvey Hello. i started having this problem. 1 2 3 keys do not work 4 fan works. also the air conditioner a / c button does not work. this part of the problem. Thank you. vehicle fabia 2004 petrol
Thanks so much I don't know much about auto repair but I was able to do this very easy and fast thank you.
You're very welcome, glad my video helped a little :-)
Brilliant, great sound & video, simple explanation and guide. Top notch mate!
Glad you liked it, much appreciated, but need to do more :-)
@@HatBoyHarvey vehicle 2004 fabia. fan 1 2 and 3. level was not working. I changed the part you showed it was fixed. After 1 month, the same part broke down again, now I changed it again. why do you think it fails constantly?
@@ye427 Not sure, maybe you just got unlucky with the part you bought or it wasn't good enough quality, but my first thoughts were: the fuse should have gone first. Maybe have a look and check if the fuse is the correct one. The control unit maybe giving Intermittent signals and effect power surges/drops. I would check the wiring and connections also.
so many helpful videos on lady penelope's fab-1, great stuff, thanks! i've got the lefthand drive estate 1.4petrol. having some trouble twisting the speed contoller resistor, nasty place to get to. i guess it will turn clockwise as it is a mirror image of yours.
Thanks, not sure about difference between L/R, but would think it is same for both ;-)
Hello Harvey,
Thank you for your video, it was very helpful when my resistor controller worked only on number four. I changed the whole resistor. A strange thing happened after that. Shortly after that one cold morning I started my Fabia and noticed that the fan wasn't working anymore even though I changed it with a brand-new one a few days before. What I did then was to change only the little element on top of it(only 0,90 st in Bulgaria) Bought three of these just in case. Shortly after that, on another cold morning, the same thing occurred. I already knew that something else was causing this and the problem was not the resistor itself. Changed it one more time. Now I switch the vent knob to zero before I start the engine(I did not do that before, always on 1 or 2), thinking that if it's set on while starting the car, the total amount of electric current for a moment maybe is overloading this little element on the first cold start. So that might be causing the issue itself. No problem until a few days ago when the vent heater started to sound agonizing like it was screaming and dying. Now I already knew what was happening. The bearing of the vent heater is destroyed, causing this awful sound, and the electric motor inability to sping freely eventually applies additional resistance to the whole electric system of the fan heater itself. The resistance(or impedance, not sure) maybe is overloading the whole circle causing the resistor to burn. Long story, but I thought it would be interesting to share this. My question is, is there a way to change only the bearings of this little motor or do I need to buy a whole new one with fan? Thanks in advance!
Update: It's unrepearable, it just not worth it. The motor is not on bearing but on bushings. I put some oil on them but the noise is still there. Just ordered a new one.
Yes you are correct, I did the very same. It's not worth trying to fix these, just replace the whole unit. Hope it fixed the issue :-)
@HatBoyHarvey Hey there! Thank you for your time! The issue is fixed and the new blower motor works well and quiet, with minimum noise. I'm very happy with it now. Thinking of this part being in the car for the last 18 years it did a pretty good job for this time. Time for the old blower motor to retire, there is nothing more I should want from it, haha. Thank you for all of your amazing videos. I know so much for my fabia now and you saved me alot of money for a repair. And most important, I love the details of your videos and how carefully everything is being removed and placed back without being broken. That is the main reason I always wanted to do the precise repairs on my car by myself. Knowing that I will put time and effort to figure out how to remove something without beaking it, while in the car shop repair, the mechanic will be less carefull i think. Now it's time to figure out from where is the boot leak on my fabialous car, it's gonna be a tough one :D !
spiegazione chiara e perfetta, grazie!
sei il benvenuto, grazie!
Thanks for your work. Greetings from Bulgaria :)
My pleasure, dobre doshli :-)
very clear
@HatBoyHarvey Hi my blower runs/blows for 20-30 seconds then stops. Any ideas as to the fault ?
Btw I've just found your channel today and you're a wealth of knowledge 👍👍👍👍👍
good descriptions
and filming
thanks4
No problem 👍
Great video ....Nice nick the car too ....Anybody know which fuse is for the heater in the fuse box please?
nicely explained. much appreciated
Glad to have helped, thanks for watching :-)
Thanks for this tutorial HatBoy.
Would it be possible to have a how-to video on replacing the blending flap and recirculation motor, sometime in the future?
Thanks for your help.
Noted
Thank you Sir,
it was really helpful to me.
many thanks
You are most welcome
Great videos, excellent explanation. Do you fancy doing a video on upgrading the rear brakes to VRS disc brakes? ;-)
Thanks, the brakes on fabi are a little weak for me too. Mine fades a bit when pushed hard. I think if I was upgrading I would probably think, fronts and leave the back, but then that may not be the right choice. My wheels made a big difference to the handling, so bigger brakes should improve stopping also. I'd have to see what people who have done it have said about this upgrade first to consider it though :-)
Thank you so much. Very informative. :)
You're very welcome :-)
Good clear video.
I am wondering if you have a video regarding the swapping of the heater matrix/radiator.
In the mornings I'm getting extreme condensation on my windscreen and a friend says it could be the matrix.
Have a look to see if the rear footwells are wet, this is a common fault in the fabia and most likley be the cause of the condensation. If no heat check the flapper motor is working and all sensors. OBD2 code reader may help here. To remove the matrix you will need to take off the centre console which I do have a video on: czcams.com/video/ogUaEX7Hkqg/video.html . Drain the system, clamp the hoses to the matrix and blow out contents before removing inside car and replace with new O rings.
@@HatBoyHarvey I will, thank you.
What a brilliant video . You should run classes on how to make these videos.
Thank you, that is so kind to hear, makes my day :-)
Great vids mate, had some of the issues mention on your vids like this and inmobiliser, scared but I will give it a go, useless at DIY lol
Thanks, great that you are having a go to fix your car, I'm sure you're not useless at all, just need to take time to find out what you don't know first and this will give you confidence to do the job :-)
@@HatBoyHarvey Much appreciated, cheers mate
Great video. Thanks...
You're welcome!
Thank you for a great Channel.
I have a problem with my Fabia. The AC is not that cold and now during the summer I need it to work. Could you make a video or tell me what should be done?
Thanks, you're welcome.The good news is your AC is working, but appreciate not very well. Over time these systems very slowly leak refrigerant and older cars more so. Pumps on older cars fail, but from what you say yours is working. Finding leaks is difficult and can take time. In your case I would just refill the system with more refrigerant (may be illegal in some countries to do this yourself) with some dye and sealer to first get it working better and also check for leaks (if any can be found) You can purchase pre-prepared bottles to do this or have it done. Be aware not to leak refrigerant into atmosphere. The instructions are on the bottle, just need to attach it to the low pressure filling port (it will only fit on the correct one) and squeeze, get as much in as possible (can't overfill as can pressure stops this). To do a better job you need to remove refrigerant legally by specialist autoshop, replace the dryer, vacuum the system and fill to correct weight, which because is quite involved (I know as I've done it) is better for a specialist to do. Hope to do a video sometime. hope this helps :-)
I really appreciate the effort of showing us how to repair the beloved car Fabia,, can you show us how to replace the radiator of the AC or how to flush it please :)
You can't just take this out without gettting the car emptied of refridgerant responsibly. This has to be done by an AC garage, most can collect the gas for you for a small fee. Once done there are other things to consider such as evacuating the system with a Vpump, changing the receiver drier, re-charging it, putting in the correct amounts of oil, refridgerant, sealer/dye.
@@HatBoyHarvey thanks a lot for the advice :)
Great channel! - fixed the door and hatch locks :). Is there a chance that you could create a video on V68 Heater Servomotor replacement? Do you know if one could just replace the potentiometer inside?
Great suggestion, thanks I will do this at some stage :-)
A very informative video - thank you! My wife’s car is a Fabia Mk3 1.9 TDI (2007). Do you happen to know if this heater/blower fan is the same one in my wife’s car? The heater controls are different in my wife’s car, and are further up the centre of the dashboard. 🙂
is it a mk1 or 2? the mark 2 does have different controls. If it is a mark 1 then it should be the same. The mk2 blower fan bit looks exactly the same to me, but not the rest of the whole unit. I'm only going on diagrams, sorry don't have first hand knowledge :-)
Hello 👋 great video. My fan was only working on no 4, I've bought the resistor pack, and also a new fan motor, the heaters stopped completely now, so I guess the motor has blown, changed fuse but still no joy. I'm going to attempt to do these two jobs with my friend 🤞🤞. Do I have to disconnect the car battery?? I don't have a manual with mine so I don't know what the radio code would be? Any help would be appreciated, thanks 😊
Change the resistor first and see if the motor then works. I don't know about whether that circuit would throw a fault code on disconnect or not, probably not, but be warned if you then get a dash light you will need to clear the code. Ok if you have a Good code reader. You need to get the radio code at some stage, you can get this online quoting the serial number, or fit a new unit with code given :-)
Cheers!!
You make great videos Harvey thank you very much. I have a 2003 1.4 TDi with 320.000km and I'm starting to get a smell off the AC system do you have that same issue or know about it?
Sounds like you need some anti-bacterial spray to kill any fungus that builds up inside the air ducts and evaporator. I've never done it so not sure which product to use. I'll look into it and maybe make a video. Scotty Kilmer recommends 'lysol' sprayed into the vent intakes
@@HatBoyHarvey much appreciated for the info, I did do it with some product but no diference, I was thinking of a more intrusive method and take everything apart to clean.... probably not an easy job too, well thank again !!! brilliant videos!!!
Hi 👋
Thank you for the video
I have a question:
I have 2004 BBZ petrol engine Fabia and it has two problems with AC system
1. There's no heating at all (I was told something about Evaporator/Heater Core)
2. The recirculation mode not working, neither the button's light nor the "mode" itself.
Can you tell me what to do please? 🙏🏼
Thanks. First check the fuses inc the ones one top of the battery box. Any lights on dash? battery 12.6V, ground OK. Coolant level OK/flushed/changed with heater on hot and fans on full, any AC at all, power to relays/relays. A diagnostic check would be useful to identify actual faults.evaporator sensor can be changed/heat core cleaned out.
Damn ty for the video. yesterday before watching this i did the exact same thing but only cleaned leafes and replaced the cabin filter, problem is there is still a noise while its working sounds like its loose but idk how to tighten it, really annoying.
took me like 20 minutes to remove the top screws now i have to remove them again :X, heater spins fine but there is a little jiggle so when i put it back on it makes that sounds, but when its laying downwards it doesn't make a sound.
once these become worn out it is best to replace them with a new or
second hand part (yours sound like a worn bearing). You say it makes a
noise only when putting it back on, so make sure it is on correctly
first. I tied to show how it's put back on, but it isn't that easy to
decribe and a bit of a fiddle to do, watch the vid closely and make sure
it seats right before tightening. Hope this helps and you get it
working right again :-)
@@HatBoyHarvey it sounded the same before and after the cleaning so i think something is just loose in the heater fan itself
If it is a dry bearing it would make noise and if it is at that stage then this would wear out the bearing causing play. They have to be perfect to make no noise, like computer fans I guess. Make sure the serial/part numbers match when buying a new or pre-used one as some are for none aircon.
I have exactly the same issue. I've been wondering how do I replace the ventilator? Is it a screw in the middle part of the ventilator which relase it out of the cover?
Watched your video again ,,so if its 4 degrees outside should my mk1 skoda heater still get hot, does it use a heat exchanger from the engine? Or a dedicated heater system please???
They use a heater core mounted at the bottom of the HVAC system. A radiator essentially. But there was an option for auxiliary heating, but very few have this and uses a lot of batty power. The heat temp you want is controlled by the knob on the control panel by demand to the desired temp using the various sensors or overridden by turning knob to full hot or cold. Often on Fabia model car gets stuck on hot or cold due to a faulty flapper motor.
Great channel! I Wonder if you could help me with one issue. I have a fabia 2003 with no AC and the air Is blowing only on botton area even if i set it up to blow on windscreen or the central area. Power blowing working fine on all speeds.
Thanks Jan. Have a look at the distribution cable: czcams.com/video/NlCNw7FtUkc/video.html as these can come off or break. If no cold AC then it probably will need checking for leaks and re-gas
Excellent videos, very helpful, cheers, thank you. Could you advise me please my heater blower suddenly stopped working after recent freezing weather. My Fabia was parked during the snow and bitter temperatures. Checked fuse but still not working. Any advice greatly appreciated
Thank you very much, most appreciated :-). Any dashboard warning lights? does the control panel light up? Have you had the fan out to inspect it, if so then you should independantly test its operation. somtimes the motor james and just want freeing up, which is a sign that it is worn. You may find that the cold weather caused moisture/ice on some contacts somewhere and may work again when warmed up which is worth a check. Check battery is good and charging. OBD2 scan may help if you have access. Keep warm, it's freezing!
@@HatBoyHarvey Really appreciate your reply, thank you. I shall wait until weather warms up, so maybe July 😁 before I know. Cheers for your advice, your videos are brilliant. Keep safe & healthy 👍
Thanks for your great videos,,
What if the fan works perfectly, but the air comes very weak from the vents, is it from the air tubes? And if it yes how can I reach them?
You're welcome, Check if the 3 speeds are working, if not replace the resistor. The flapper vent maybe stuck on hot or the diverter control cable has detatched or broken. It is unlikley the vents are completely blocked up enough to effect the air too much, but is I suppose possible. The front and side vent adjusters/covers come off.
Hi, changed the resistor pack and still only blowing on no.4, any ideas please? Great video btw 👍
Oh, never known that, good question, anyone, I'm stumpt` if it does work on 4 then it shows there is power to it,just not enough perhaps. test the voltage and work from there, should be 12V.
Thanks mate, you've helped me a lot with these video.
Few weeks ago I had water broken, I was at training centre hwne this happened, we didn't knkw it was watwr pump, my tutor por some liquid into the radiator said this will block the leak, but it didn't, infact that product affected my heater, since then the heater didn't blow a hot air, can feel a little warm air, ON number one after driving for hour but when I turned up to number 4 total cold air.
Is there anyway you can help me with to clear the heater which I've been told it's inside the dushboard. Can you advice please?
I haven't done a video yet on the heater matrix, but hope to do one at some stage given time. It can be a little messy if you don't know what you are doing as some water is involved. try flushing your system out with a hosepipe, but be mindful that in some cases it might create some leaks :-)
@@HatBoyHarvey hi mate when you say creat leaks, you mean from where the leaks?
Excellent! Really useful. Do you know the location of the interior temperature control sensor? Since new (along with other out-of-the-factory faults, but that's another story) the heater has been Nothing-nothing-FULL ON INCINERATION FIRES OF HELL OW OW OW IT BURNS over the first three notches of the dial. Any ideas? New video, perhaps?
Maybe you have auxiliary heating? For such extreme an experience, but this often happens without that when the hot/cold flapper control flapper motor starts to fail or simply wears out becoming temperamental :-)
Sir once agsin thank you on an excellent video. My Skoda fabia 1.4 mpi (50kw,model with air conditioning) sometimes heats when it is on cooling,and sometimes cools when it is on heating.If I turn the ignition off,and then I start again,after a minute or two it becomes OK.Could this resistor be the cause?
If the fan speed works OK I wouldn't change it. I have had the same fault, which went away a day later. I haven't yet found a definitive answer to why this happens only guessing it could be the main heater control unit or it's connections at the back. I've had mine out, disconnected it a couple of times and re-connected it and that fault hasn't returned, but it might not be that at all anyway. The vent air flapper motor for hot and cold goes faulty on these so that is something to be aware of. I haven't yet done a video on that yet as fitting new ones may need re-calibrating with VAGCOM :-)
I recently got a Fabia 2009 and the ventilation system was perfectly fine for the first month but now that winter is setting in it started making a noise when i start the car ( cold in the morning) It only last for a minute or two and once the car stop being cold it goes away. It sounds like a high pitch hum. The vent speed doesn't seem to effect the sound. If i turn the heater off the noise stops but the different speed settings doesn't effect the sound that it makes. Just got the car so a bit low on finances to start bringing it to the shop. If you have any thoughts about it i would love to hear them.
The sound itself doesn't really annoy me all to much its more the thought that something might be wrong and in need of fixing before it gets worse and breaks itself further.
where is the sound coming from? sounds like that are often heard in the engine bay, serpentine belt etc
Watched your excellent video ,but my problem is my fan speed works ok,but I'm not getting heat from the system at all only lukewarm can you help please?
This is often down to the informous flapper-motor for hot/cold getting stuck, if pressed you can take part of the dash out and move it by hand to hot for a temp fix, whilst accessing it 'test it's operation and you may see if it is temperamental or not. Certainly do a coolant flush and a separate heater core flush, change the thermostat. OBD2 diagnostics will highlight any sensor failure elsewhere, but you can clean the cabin temp sensor with a brush. As long as you don't have the AC button pressed a dead AC pump won't effect the heater circuit :-)
You can just replace the the thermal fuse on the resistor... by carefully soldering a new one of the same value (available from Maplin) noting which way round it goes .
yes, good point, I was waiting for someone to mention this. I know you can do this and it will only cost about £1.50 ish (as a rough guess) if you want to go that route. It would be very satisfying to do like that :-). But is it really worth the trouble when they cost £6 - 10 for the whole thing new online?
My fan speed working only on 4 now i know how to fix it thanks man :).Also in the same area when you was showing where the fan speed sensor is from that area cold air is blowing on passenger feet maybe you know what it can be?
my passenger footwell also seems to blow colder air than the drivers side and always has, not sure what this is or if this can be fixed. replacing/cleaning all the sensors and connections may help.
@@HatBoyHarvey Big thank you 😎👍
i got my skoda fabia 2000, the air con is not working, mechanic said heater sensor inside heater box need replacing.
as he said the sensor tell the compressor it’s cold enough and don’t not work, so no matter i push aircon button to turn on still no cold air coming out.
can you help me in a video
pair in mind, compressor replaced and regased it
thank you
Sorry you are having problems with this as it is so hot now. The flapper motor servo could be stuck on hot, even though the knob on the front panel is turned to cold (AC wont turn on on hot). This is a common fault and I haven't a video on this yet, but plan to do one. you can manually make sure it is turning to cold by taking a few panels off and help it a bit if needed. Check out my video: czcams.com/video/X0a0_x7q5aY/video.html this shows you where it is+cabin sensor. I would look at these first. also you may consider the ambient outside sensor: czcams.com/video/ZuZRC3w8g8s/video.html and the evaporator sensor: czcams.com/video/HpPAoVx1wJk/video.html
HatBoyHarvey, have you done a video on noisy aircon unit? When I switch the aircon on I get a humming sound that increases and decreases with engine revs... I have seen elsewhere that my Fabia could need a re-gas which I have done, but no change to the noise. Great Videos
Not yet. You can get a wooshing sound on pressing AC, is it that?. Where is the sound coming from? noises often emanate from the pump motor as these can fail. Do you still get cold air, continuously or only for a short period, intermittent or none?
@@HatBoyHarvey Thanks for the reply. Cold air works fine and continuously. There is no wooshing sound on pressing the AC button. It might be the pump is on its way out - when the aircon is on the humming speeds up and down with the revs of the engine
Dear Harvey,thank you very much for this exzellent video. My heater-ventilation sometimes makes a beeping sound. Is it possible to oil the motor or must I exchange the unit? Thank you and best greatings, Mathias
Many thanks, If the beeping is from the dashboard then this indicates a fault, but if your saying it is from the fan then I would probably try to do that. There are some clips on the back of the moulding that releases the motor @ 4:58 if that helps. Do you get any dashboard warning lights?
@@HatBoyHarvey No, I hear it beeping sometimes, when the fan runs on level 2 . When I switch to a different level, beeping stops soon. I guess I'll try to oil the axles of the fan with a little bit of silicone spray. Thank you very much for your excellent advises and soon answering, dear Harvey
By the way: there is no warning light on the dashboard...
Hi. You have a great videos. I have Skoda Fabia (2002) and I have problem with temperature control. The knob for control a temperature of air blowing in cabin does not work or work very slow. For example I put the knob to maximum heat and then start the car, after that the air that blows is hot but if I turn knob to the minimum temperature the air is still hot for about maybe 5min and after that it starts to blow a cold air. Do you maybe know where is the problem? Thank you
Thanks Mirza Bulb, glad you like my videos. When you turn the temp control knob to full hot/full cold it acts like an overide to give max settings. If it doesn't get cold quickley it is likely to be the flapper motor servo getting stuck which happens a lot with older cars. my video on dashboard centre fascia shows the location on this. czcams.com/video/kpv-mzBT8dQ/video.html :-)
@@HatBoyHarvey - Thank you. First I try to clean a cover for sensor for cabin temperature and sensor it self, after that I try to reach and replace a servo motor.
@HatBoyHarvey - and one more question. Is that motor responsible for recirculation of cabin air because I turn on recirculation and after minute of two the recircualtion are turn off and I cant'n turn it on again until I start the car again.
Looking to replace thw sensor that controls the fan speed, what isnthe name so i can order this and replace. Thanks
heater blower resistor: 6Q0959263A
that sensor only controls the fan speed?Sometimes in summer i had it to give me some cold air and he give me hot air in the cold position,and cold in winter. do u know how to resolve that?
Yes, fan speed with overheat fuse (cheap to replace). Have a look at: czcams.com/video/kpv-mzBT8dQ/video.html 8:02 and 9:57, That sounds like the flapper motor getting stuck on hot or cold, which I've seen a lot on older fabias. Check flap actuation when stripped-down.
Do you know if it's the same process for a MK2?
Sorry, not sure, my guess some parts may be similar or improved. I'll have to get one to find out :-)
can you help me, find the air conditioning drain pipe, on my skoda fabi1.2004
Behind heat-protection matting of the bulkhead below the evaperator lines.
Hi and thank you for all your videos, am a subscriber, but didnt expect ill be needing help, I enjoy knowing my car parts by your videos, but recently my 2000 octavia mk1 electronic heater stopped working, I can see the screen control and that i can adjust fan strength and temp on the screen, but there is no fan blowing at all, no interaction, the heated seats also stopped working, as well as ac. can you help me please
Thanks, and thanks for subscribing. It sounds like a fuse. First have a look at the fuses in the battery box as this can be suspect to overheating, maybe fuse has blown there. Check battery has good charge 12.6V and 14V+ when charging. Fan resister speed control goes and is cheap to replace. Check all connections and relays for the seats, but my guess is it is a fuse and as some system incorporate other systems then some of the main control fuses need looking at, not just specific ones. hope this helps :-)
@@HatBoyHarvey Will do, and keep you updated, thank you very much for help and reply.
@@HatBoyHarvey Hi, I checked all fuses, battery, they are all ok, in car and over the battery, what will you recommend please, blower or heat sensor? Thank you very much for reply
@@mycomment6699 If you haven't got OBD2 diagnostics which would help pinpoint the issue, then you will need to check further in more detail the circuits/connections/wiring involved. Certainly check the fan and fan speed control resistor which you could test with a multimeter. Is the outside ambient temp on the dash working? the internal one can get clogged with fluff and is fairly easy to clear with a vacuum and brush.
@@HatBoyHarvey OMG, it was bloody raining and snow today, i have an obd 2 scanner with me, but weather forced me to finish soon, did not hit me to use it, i checked all fuses with the multimeter.Ok, will do, and keep you updated, can not express how much i do appreciate the reply, thanks man.
Hi there, great video - very useful info. I plan to replace my fan speed control sensor soon as it is only working on 4 only and I suspect this is the issue. In terms of disconnecting the battery before working on the car, is it sufficient to just disconnect the negative terminal only or should I disconnect both terminals? Sorry if this is a basic question but I just wanted to check as I’m an amateur on car maintenance. My fan is also making a noise from time to time which I’m hoping is leaves which can be easily cleaned out but if the fan is damaged, is it an easy job for an amateur to replace it? Cheers.
Thanks, just the negative earth lead. once you have access to the fan you may be able to find out what the noises are. Fans ain't cheap, if you can fix it removing leak, great :-)
@@HatBoyHarvey thanks a lot for prompt response.
Replaced fan speed sensor today and now have 4 speeds fully working 😀 was quite tricky, but lots of jiggling and patience won through! No leaves in fan and no obvious reason for intermittent noise - will replace If it becomes too frequent. Wouldn’t have had a clue but for your video, many thanks again 👏
Thanks, glad you were able to jiggly-fix things. Love that word 'jiggle' :-)
@@HatBoyHarvey thanks for the great videos. Can I just ask for some advice, I've replaced the resistor and now have speeds 1, 2 & 4, but not 3?
Any ideas?
Cheers
What can be my problem . My fan was blowing only on 4th speed so i changed the fan sensor that green thing it had blown fuse and the resistors showed bad resistance only 3ohms , so I changed it for brand new and after couple weeks it broke again , the new sensor cost just 20€ but what could be the problem with it ? I dont want to change the sensor and have it broken again soon .
I would check over all the circuit connections relating to the fan/upto the fan and then have a look at the fan itself. If it is worn then it may be taking more current to run, overloading the circuit and blowing the fuse and speed sensor etc. Hope this helps :-)
Hi , so I tryed to fix it myself .
1. I measured if the Resistor Pack is broken or it has blown fuse , as show in this video : czcams.com/video/LUNvzyvn8J8/video.html&t . It turned out that my resistor pack are all ok in terms of their resistance , they had blown fuse . So I changed resistor pack fuse , as shown in this picture : ibb.co/g418c1H the fuse is combinated fuse 10A and 216C you need to make sure that the body of fuse doesnt touch the two middle points .
2. I took the heater fan out of the car using your tutorial , there was no debree in the place of the fan , but the fan was cowered with dust , so i took the whole motor out and tried to clean it as much as possible . Then I put some engine oil (5W-40 was only oil that I had at home) on the bearings . Here is video that I followed on how to take the engine out of that plastic holder , It is in russian and it is diferent motor but the principle is the same video : czcams.com/video/ak2Shg8CRrU/video.html .
Here are the photos of the bearings :
bottom one (you can acces it only if you take out the motor from holder ) : ibb.co/nQynxq9 this bearing was full of black powdery dust so I gived it good clean .
The top bearing is pain , but you should get sense of how to take the fan part out and oil it . I used long siringe to get the oil on bearing photo : ibb.co/dDNXWwb the bering is just under the white part .
3. The fan part that white pastic was too covered in black dust so cleaned it as much as I could , I used minimum water becouse I thought that water will damage the motor , but you can use water and then spray it out with compressed air . Here is video from russian mechanic on how to clean the motor for good czcams.com/video/YAcnemZo8ds/video.html , I understand just little russian but he shows it perfectly , in my case I do not have compressor so I did not use as much water .
The I just let the whole fan dry out , and instalet it back in the car .
But now the fan vibrates on 3 and 4 speed . I don t know why , I checked it holds good in that plastic , I think that I need to again take it out and trim the fan white part . becouse it was hard to get all dust out of it , and I think that now it is out of ballance or something .
I may just buy the new one , but I just wanted to fix it myself , but it s pain in ass :D I m just trying to save extra 90euros for new fan that s all :D
My fabia is mk1 2005 . And the fan is factory one .
Hi , I changed the sensor of the heater but still working only up 4 speed , Do you know what the problem might be
If it works on 4, but not the lower settings you know there is power to the new sensor so that can safely eliminate it. I would clean the cabin sensor and check the connections on the temp sensor behind the control unit/or replace that as well. Check all cables/connections/continuity.You could try using OBD2 vagcom or other which may or not narrow it down if you have access to that. The actual switch or fan may be faulty, but I doubt it. I beleive the heater/vent control unit module can be reset, which may work and you know the infamous flapper motor gets stuck with heat build up and age and could possibly cause cause the system to malfunction. Check, test and replace is the only thing I can offer I'm afraid, hope this helps and you're able sort it eventually:-)
I push my recirc button when cars first running and clicks off its self within a few seconds then doesn't work again. Could this be the recirc flap motor thanks
Yes, it maybe stuck though, so you may be able to free it up. try activating it and moving it by hand a number of times. If that woks I would then use silicone lubricant on moving parts. If it doesn't work at all then a new motor unit would need to be programmed in with vagcom etc
@@HatBoyHarvey thanks for your reply I will try that. I allso have recently purchased vagcom is it easy enough to program new part in if it needs replacing. Currently getting my head around vagcom haha
Hi my recirculation has stopped working it used to come on when in reverse. If I press the button it lights up then goes off about 5 seconds later. Iv looked at the blue cog and it still opens and closes the flaps when I press the button but only seems to open about 1cm. Is that normal?
I've heard of this, but never tried it and maybe it is only on certain models. It is a safety feature when selecting reverse gear to prevent exhaust gases entering the cabin space. Yours does sound faulty to me and need investigation. You could try lubricating and moving the mechanism by hand whilst it moves to see if it is the motor. These are often faulty intermittently and not easy to get to fix as they have to be set up correctly to work properly.
@@HatBoyHarvey I managed to slightly disengage the motor cog to check if the others moved and they did turn the flaps really easy. They open really wide too but for some reason the motor only opens them a tiny bit.
I keep smelling exhaust fumes in the cabin when I stop too so wondering if this could be something linked to that
Hi there, I am trying to locate the AC drainage pipe, any idea where it might be.? Thank you!
it is on the bulkhead behind the foil next to the heating pipes. it is a bubble
@@HatBoyHarvey I was looking under the car but eventually it was as you said, many thanks.👍
I did the speed controller on a car this weekend and after that the fan is very noisy. is there any way of lubricating it?
Firstly check if there is somthing touching the fan like leaves. If it is the motor/bearing then in theory you could grease it, but I guess this may not last very long as the bearing will be worn. I've never done that. You would have to take it out and try to get at the bearing and may have to dismantle it. I don't know if the bearing can be replaced, but my gut feeling is it maybe housed in plastic and either not possible or not worth doing as replacing the fan is easier and not too costly if you choose a none OEM unit :-)
@@HatBoyHarvey There were leaves in it. that have been removed. Might be I forgot to connecet the hose aswell that might slightly affect the balance. The owner doesnt want to put much money into the car so thats the reason I ask. The noise is worse at lower speeds so its probably the bearign and then a new fan will be needed because theres no point in taking the time to restore it. Thanks. :)
I have a problem also with The ventilation, because it is not heating at all. On The first 30 seconds it seems like is working and hot air is coming, but after that it turns to cold one... Do you have any ideas?
There could be a number of issues with this depending on mileage and age of car or just one. Check water level - thermostat -- belt that drives the water pump/adjust/replace-water pump? - flapper motor closing?- blower fan working?- replace all heating/temp sensors -fan speed? -flush heater system/matrix. Or you could hook up OBD2 reader when it stops working to see what is going on. Hope this gives you an idea; go through systematically, starting with checks then replace :-)

Great video, can anyone do a time for me tonsee where the 'air recirulation flap motor'can be located?
If you look to the far side of the fan unit you can see the blue toothed wheels controling the flap for recirculated air.
@@HatBoyHarvey thanks alot pal, appreciate it.
@hatboyharvey do you happen to have a part number for the recirculate motor you mention (blue cog part)? Thanks
@@jimmymach6588 I'll have a look for you, what are your cars symptoms?
recirculation motor RHD 6q2 819 453 LHD 6q1 819 453
I've changed the resistor but my blower still isn't working, does it matter if it's not seated properly?
yes, it needs to seat properly or the fan will jam, check the fuse then see if there is power to the unit, if there is then try turning it whilst connected, sometimes they can stick.
@@HatBoyHarvey how do I check for power I don't have s multi meter to hand?
You can use a test light. £2.00ish from motor factors (looks like a small screwdriver with wires on) or attach/solder two pieces of wire to a small 12v lamp, one end on the connector turn the switch on, the other to ground. Hope this helps :-)
What is the partsnumber on the sensor?
Found it. 6Q0 959 263 if anyone needs it. Great video, thanks!
Awesome video. Is that airplane engine I hear on 4:19? :)
Nope, think it was the cat or the wife wanting tea!
@@HatBoyHarvey haha, I meant 4:09 but good info on 4:19 :D
