Hi
This car came to me blowing the fuse to the HVAC fan...
Follow me on this video to find out what was the problem and how to resolve it.
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching! - Auta a dopravní prostředky
Thanks very much for this - great to re-instate speed 2 on my heater fan. The crucial issue is knowing where the part is and how to access it, and your video made it easy to find. In fact some previous mechanic had simply taped back the speed 2 wire, where it had melted out and no doubted shorted! I simply soldered a new wire in place as you suggested and all fine.
That's great!
Nice to know my video helped!
Thank you for watching!
Great fix. I recently fixed my brothers Grand Scenic heater resistor plug, that was melting and causing resistor failures. The fix addressed a few problems, one making it easier to access. The replacement plug comes with a loom, so we cut and use solder shrink to link the cables. So now, if the resistor blows, it can be changed outside the aperture of the dashboard, due to the extended length of the loom. Renault electrics are terrible.
Good job!
Yes, Renault wiring can be very flimsy...
Thank you for watching and for your comment!
had this happening on the girlfriends megane about three years ago, just kinda repaired the molten plug and it was still working when sold last week, your repair will probably last the entire car lifespan, good job luis!
Hope you got something better...😋
Thank you for watching and for your comment!
Had the same problem myself, Renault electrics and connectors seem to be poor quality and underrated for the current, like your videos.
Thank you for watching and for your comment!
as always a creative repair that solves the problem. Well done 👍
That's the goal!

Hey great vídeo! The french suffer from this... My sister's 307sw back side headlight (mechanic did a bypass for the ground) and my 308 back side headlight (the ground was toasted) that I have repaired today...
Thanks Luis :)
Good work!
👍👍👍
Well it's a fix 😉 This car is a real problemchild. Thanks for sharing Luis 👍
Thanks Dylan!
For watching and for your comment!
thanks Mr, Luis, always enjoyable to watch ur video and learn more ways to do the fixes. cheeeeers
Thanks!
👍👍👍
Excellent video, owner will be surprised how well his modus is going to be. A little knowledge is a dangerous thing ( changing to 25amp fuse)

Plugs are about £8 on eBay if the customer doesn't want to go down the dealer route. I think Pages etc. do repair kits also. With all the recalls across most manufacturers for this sort of thing I wouldn't be opening myself up for potential aggro.
Enjoy yr vids, keep it up 👍

Hi Louis!
I encountered such a malfunction. Contact overheats due to huge current! It is necessary to measure the motor current. Perhaps the current is above normal. Replace air filter (engine overload).
I look with interest, Denis!
Hi
It is poor connectors really...😉
Thank you for watching and for your comment!
Great video .. very helpful - thanks. Mine has a similar fault, but not exactly the same .. the fan is coming on the whole time at maximum speed, no matter which position the control is in. But as in your video, it is a burned connection in the connector to the resistor module. I will decide now whether to bypass the connector as in your video, or get a new connector and heat-shrink the wires.
👍👍👍
Hi you probably know this but it's a common problem and you can get the repair connector and wires from Renault they do it in kit form but good video
Yes... next time it fails will have to get one... but so far still going...😋
Thank you for watching and for your comment!
Nice, easy one for you 😃👍
Thing to be wary of soldering high current cables is the high current can unsolder the joint. Hence why they crimp connections. If you do want to solder, a way round this is to wrap some tinned copper wire around the joint, in effect binding the wires together and creating a good physical connection. Then solder up the whole thing.
yes you are right
Nice professionel job friend.
Thanks!

Could somebody please explain to me what is being used to test the resistor with the 2 bits of cable he attaches to it? I'd really like to know so that I can do a test on mine? Thanks
Nice fix 👍 but if in the future the resistor is faulty, do you also need to solder the yellow wire directly to the blower resistor?
I think if it fails again, I would just get new plugs and resistor...
Thank you for watching and for your comment!
Great thanks

hello mr louis pls i watched the video on how to get diagrams and i tried practicing but i have failed several times. pls can u explain to me , how u search for them? you search criteria could be helpful thanks!
Hey Mr. Louis i would like to thank you for the video for it really helped , second i would like to ask you a question , i have my scenic II 1.9 dci 2004 and iam having a problem with fan blower ...it is working but i doesn't go off even if i tried to put in low speed it always stay the same high or low speed ...what could be the problem?. please help.
Difficult to say... but a shorted resistor is a possibility...
Thank you for watching and for your comment!
Good Job , very known problem with Renault, you can by on eBay new Plug.
Correct...
Thank you for watching and for your comment!
Just enquire today I was driving on motorway for 4 hours this car. Once i got off the motorway and sat by traffic light i realised the there is a small amount of smoke coming out from under the hood. The car was not overheating it was in normal temperature. Any idea what it is?
Which row and number in - is the fans fuse on? I tried to replace which I thought it was and it didn’t fix it 🤷♂️ or perhaps I need to try what you have here.
My fan stopped working yesterday. When it did work - it only worked on fan speed 4?
1 - 3 did nothing at all.
Check this as per the video... it is a common issue on these cars...
Thank you for watching!
Be aware the rear light cluster multi plugs also suffer from contacts over heating causing the plastic plug to melt, usually happens to the earth connection, solution is to make a permanent connection to body from the bulb carrier assembly earth terminal.
This happens on most french vehicles and ford transits.
Thanks for the tip...
👍👍👍
em algum momento aquela resistencia ou motor falhou pra ter feito aquele estrago e o fusivel mais amperagem tambem nao ajudou nada a festa, nice job
😊
👍👍👍
Did a similar one on a Fiat this past week. a 30 amp fuse was put in place before calling me and so half of the hot cable to the fan got burnt and rock solid... why do some mechanics think fuse amperage is chosen randomly?
😂
Absolutely...
Have you seen the videos I have done for the bmw F10?
A very good example...
Thank you for watching and for your comment!
@@LMAutoRepairs Yes i saw that video! Also i would like to thank you for your forum, It helps me a lot on the field being able to talk with techs like you, ecutech, Rookie, candiagnostic. Have a good sunday!

A pleasure!
Oh wow i have a kangoo the blowers only work for a minute in morning then stop. The uch is clicking like cutting blowers off. I reckon this could be the problem.
☺️
👍👍👍
Do you know if it is possible to get access to the connector which joins the red & black wires (from the resistor module) to the blower ? The red & black wire seem to go up inside the dash .. I guess there is a connector which joins these wires to the blower, but it t looks like I will have to remove other parts of dash to access it ? Thank you.
Hi
Sorry... but I can't remember now...
👍👍👍
@@LMAutoRepairs Thanks anyway - this video was a great help :)

Do you think the Renault Megane Shaker will be the same concept, it just stopped working
Most likely...
👍👍👍
I have a strange problem, similar to this on a 2005 Modus, where fan settings 1 - 3 works OK, but when I put to 4, it stops completely. Like you put it to 0 again! Very strange. Do you have any idea why this could be? Thanks!
No... you need to do your own checks to find out what is wrong...
The resistor still a good point to start...
👍👍👍
Watching while Selco opens up!
Thanks!
Hope it takes at least 10 minutes to open...

Great video again (-:
Question:
Do you have any contact details in fact I would like to ask you about something please
Thank you

LM Auto Repairs ok,
So I would to bypass EGR system and would like to know your opinion about the situation
@@christopheveriter8806
Which car is that?
Best way still, will be to do it on the ecu software...
where can i get those pin connectors? Is there a specific name for them? I dont want to order a full socket.
I got them from eBay...
Thank you for watching and for your comment!
tyhose connectors were used in the laguna 1,for the behr or valeo fan (airco)you can t buy them at Renault......
Correct...

Hi
I do this as a part time...
What is the problem?
Thank you for watching!
LM Auto Repairs won’t communicate with our diagnostics machine, it will only find radio when doing a scan, thought it might be engine ecu related so purchased another ecu, had it cloned and still can’t communicate? Checked all fuses all good, car has got misfits which think might be injector but no way of diagnosis! Or even coding new injectors?? Think there is a problem on the communication somewhere?
Possible fuse box ? Bcm ??
@@series1glenn
Stop throwing parts at it...
Check can lines... if you have a scope, the better!
Otherwise measure wiring...
Check power and grounds to the modules...
LM Auto Repairs wouldn’t know where to start on checking can wires as cant find any information anywhere re wiring diagrams etc ! Hence why asking for your help..
It won’t find the uch/ucm?? Any ideas of pins to check at all please??
Hey, hey. I have the same problem. How is your solution working after all this years?
The car was not mine... all I can say is that I was not asked to look at it again...
So I would guess, still going...
☺️
@@LMAutoRepairs That's always a good sign.
My car is RHD so it's a lot harder to get there, but I'll do it your way. Just need rubber hand to unscrew resistor unit.
Thanks :)
👍👍👍
@@LMAutoRepairs little info for those whom may concern:
My problem was lack of 4th gear. Socket, plug and insulation around green wire were melted. But that wasn't the issue at the moment, since it wasn't making shortcircuit. I fixed it the way that is shown in video.
Lack of 4th gear was caused by lost of contact in plug for the thickest cable, violetish one. Since it's pretty big and hard to solder, I used Wago x3 to connect it to the black wire outside the resistor box.
In later version of Renault cars, this resistor had 2 more contacts to lower the current which flows thorugh them. If you want to fix this thing in most elegant way, you should buy new plug with 7 contancts or more (you can leave the rest unused) and new resistor with 7 contacts. You just bridge this two extra pins with 12V and ground cable. With resistor you will get new connector for fan side. Take care of it's shape, because there are two of them, however you can cut old one and fit it to new resistor cables. Good luck :)
one issue you didnt messure the current of the fan,in all the speeds,it could be an problem with the fan.
Yes it could...
So far still running... so guess the fan was and still good... but definitely I get your point!
