Well guys, the time has come for me to bow out of this thread, I hope the pictures in post 17 help many folk sort out their heater resistors.

I sold our Scenic to webuyanycar last week, no more dodgy heater resistors, egr valves, turbos etc for me!

Over and out.

Question Re: Renault Scenic II - Access the resistor pack in 5 mins.

HI really good how to guide, Still not looking forward to doing this! Can anyone tell me where to find the fan blower so i can fit the new resistor pack and run the red and black wires to the fan?

Any Help would be great!

rang my local dealer 52.73 +vat for the resitor & 31.11+vat for the loom then the cost of 2 hours labour ! WHAAT!

Re: Renault Scenic II - Access the resistor pack in 5 mins.

Hi, folks, going to add a bit to this thread.

My issue, was fan stopped working on all 4 settings.
Accesed resistor via dash as per forum, after wiggling connector, fan started. Great i thought however i soon noticed the yellow/brown wire was getting very hot. Removed connector plug and on inspection noticed some was melted.

So decided best course will be to replace loom and resistor. Took out the single screw holding the resistor in but like some other posts the resistor would not come through dash as the red and black wire to the fan was too short.

The solution in my case was basically to tug the red/black wire, it seems to be in some sort of clip on top of the motor housing. Now of course you have to be careful how much you pull. Seems i guess some are clipped in and some are not.

So now i have everything nicely sat outside dash. As soon as dealers open i will get parts and fit. I intend to post pictures before and after as i think some people are still a little confused as to the the splicing etc.

Ps. One thing i did learn today is that the resistor seems to need the air flow in the ducting to stay cool :loser:, so dont do as i did and run the fan with the resistor out !!

Will update the thread as i do the repair.

Re: Renault Scenic II - Access the resistor pack in 5 mins.

A useful thread
I have had a problem with my fan not working on position (2).
Initially I thought this would be the resistor pack failing, but after looking at how it works, it became clear that if the resistor on (2) had failed, then (1) would not work either (resistors wired in series and (1,2,3) pick additional resistors, 4 bypasses all resistors).

I firstly checked the output on the fan selection switch and found it all okay (wrt to 12v), so realised I was going to have to investigate the resistor-pack end.. Interestingly enough Renault have used two differing gauges of wire and noticed that two of the outputs are thinner wires - one of which is (2) and I believe also (probably... I didn't check) (1)...

I followed the instructions here and removed the display panel, etc. You _do need thin arms as I managed to scrape mine a lot doing this job!!

Anyway I managed to get to the connector to the resistor pack and realises it was charred and damaged on the thin yellow/white wire.
Looking at the connector on the resistor pack, that was also damaged.
For now I've just managed to push the connections together, but to d a proper job I need to take the dash apart 'properly' as unscrewing the resistor pack screw on the LHS and then unclipping (& breaking(!)) the RHS did not give me enough leeway (due to the red & white (?) wires at the top of the resistor pack not being long enough to allow this).

I believe these thinner wires on the lower fan settings are not of a sufficient diameter for the amount of current that is drawn; maybe this caused the burnout.. I'd be interested in other people's ideas on this.

I will post some pics later... if I figure out how to.
