Megane Mk2 Interior Fan Not Working - Heater Resistor Change

If the interior fan on your Renault Megane Mk2 (2002-2009) is not working, the most likely cause is a burnt out heater resistor. This video shows how to locate and replace it.

Thanks for the video. Replaced my heater resistor unit today as it had a intermittent problem. This video saved me bags if time. Brand new unit cost about £18 from local Euro Car Parts centre and a couple of hours to fit.. I gave fan motor unit a bit of a clean at same time. Now works fine. Thanks again.

Many thanks for clear video. Mine was just a bad connection to the resistor. cleaned it and all works fine in all settings.

Best step by step I've found and now position 4 works again, thank you for your efforts :)

Dear sir.I am so pleased I found your video.a superb presentation.very clearly spoken, methodical, and thorough.
I am in the process of trying to change the brake light switch on my good friends, 2005 Renault scenic.I coudnt have asked for a better view and explanation.
I know this video is actually for the heater resistor block.but am made up non the less.I got a birds eye view of the brake light switch.thankyou loads Ste.keep the great work and videos.

Thanks a lot! My wife was so angry and wanted to change the car because of that fan. I did not want to spend much money on the 15 year old car as it has many other problems. I managed to change the whole piece, however I found difficult to remove the top part of it. It is only by looking at the new piece and feeling the various cables and bits under the dashboard that I understood. It is a great video

Thanks to your clear, easy to follow instructions the job cost me £ 8.50 ( for a heat resistor off flea bay ) instead of £ 240 at my local garage . Thank you and have this drink on me 🍺
P.S. the fan was not working on settings 1 and 2 .

Had an intermittent fan issue and now seems to have given up entirely (it was working on setting 3 for a few days): is it likely to be the resistor or the fan?

I have a renault twingo 2011, would the heater be in the same place ? I can't find anywhere that shows me, my heater and cold air does not work at all ( after weeks of it making a funny crunchy noise)
Slamming the door worked for a while but now I think ita finally dead, any help ? Much appreciated

1:59 Did you manage to fix the leek in the passenger foot well?
Thanks for sharing this. Helped a lot.

Hi if I have to change the fan does it come out passenger side or drivers side

[mikebeswick]

Hi. Great vid. My number 4 fan doesn’t work. Could this be the same problem.

[atheist]

How long it would take for a professional worker to change the heater fan and the resistor for that car ? For my car they say it took 3 hours

Hi IoFix, I have a problem with my car alarm going off when I lock it.. It only happens in the winter (presumably when we have heavy rains), do you have any advice, or perhaps a video to help rectify. Just to add, every winter I additionally notice my rear lights going into 'disco mode' I've preciously found burnt out connectors, but wondering if there's a deeper issue that causes it to reoccur when it rains. I'm quite handy so as long as I can watch videos like this I can cope with ordering parts and fixing. Grateful for your videos and any further advice you may have for my megane 2 issues, thanks! 😊

Hi ... I have a similar problem.... So today I ( with help from my son Stephen ) removed the resistor and looked at the the terminals on the block connector, all where good and no sign of melting plastic. Stephen  checked the little resistor that sits at the end of the green stuff ( sorry not sounding very professional ) and it allowed power through, does this mean resister pack is ok ? Question :- How do I know/check the resistor is at fault before I purchase a new one ?

[grahamhiggins]

where does the red and black lead go to? I can't seem to trace it... do I need to cut and solder it on?

[zzhughesd]

I’ll go here first. I should check fuses but just know it’ll be resistor. I have zero fan speeds.

Will this fix work for laguna II as well. Same issue, blower not working on 1, 2, 3.
