Final Stage Resistor - How To Replace

Recommended Posts

Mine was pulsing for well over a year so can't really moan that it went.cost just over £40 from euro parts for the good one, think it's hella,I know you say to take the seat out but don't think it will help you much as that's not really the problem,it was not been able to get to the top motor screw which you have to remove and the steering rack is in the way and pedals are in the back of your head and normal torx don't fit as either too thick or too long,mines an auto so I would say is abit easier than a manual hence having a pedal missing so more room.like I said before I'm only 5ft tall so really feel for you normal size folk lol.i would be willing to help anyone out doing this if your in my area as I think once you've done it you know how to get it out without much fuss.

Done mine the other weekend. It is actually a really easy job but I just spent most of my time trying to get the screwdriver into the screw head as I couldn't see it! I ended using my phone camera to guide me!

Just finished doing mine. Was a right pita in this heat. I found it easier to take the recirculating air vent motor and positioner right out of the way to get access to the awkward screw at the top of the fsr.

Thanks op for the guide.

You're best getting a genuine one from the dealers use realoem to get the part number. There is a real good vid on youtube of this kid trying to get the old one òut. When he finally does it then he has a new nightmare, the one he got off ebay is a few mm too big so doesn't go in. He ended up having to shave/sand bits of the plastic down just so he could get it installed.

Once you master sticking your head in the right place, and find a good place to put your phone to show you where the top screw is, the job is actually quite easy. The key is "thin" torx tool, I found the perfect one from toolstation, will try and dig out which I used. You can use your fingers to locate the groove/channel leading to the difficult top screw, makes things easier, just need a thin enough bit, else as you push it in, the plastic moves it away from the screw. I wasted 60 mins with too thick a tool, then resolved it in 10 mins with the right one.

This pic shows the groove/channel to locate:

I would use my fingers to locate the groove, put my torx bit in their and slide it forward, but kept missing and it got very frustrating, it kept going higher and missing the screw, then I realised I need a thinner bit.

Oh and disconnect your battery!

I just did this job and i manage to take the 2 screws out but not the stepper motor house so i just left it loose and took m stepper motor out only. I notice it was stuck to the rod so i left it just in case it would break something. Botton line is i manage to still pull out fsr and i repaired it and put it back in.

When I did this job last year, one thing I managed to do was snap a bit of plastic, the one the stepper motor uses to drive the blowers I guess. The plastic is housed on top of the case that the stepper motor is plugged into (the two difficult screws you remove to access the FSR are actually holding this case in place). Anyway, I finally bought a new case from the stealers for 8 quid and replaced it yesterday. Getting your fingers etc in the right place is still tricky and having a flashlight lying by the brake pedal permanently during the job does help! Anyway, here's some pics of the old case which may help people work out where these two screws are:

The case is roughly oriented like this while in situ - the lower screw is easily visible, the stepper motor clips into this case, the rotating part of the motor fits into the plastic on the top. The FSR is behind this case/motor as you look at them in the footwell, and can be accessed once you move the case out of the way. You can see the bottom hole is the screw you easily see when it is in situ, the top one is the hidden one.

You can see the groove to access the top screw here. This is the key to making this job take only 30 minutes instead of 4 hours. Locate a Torx t20 bit thin enough to slide down this groove and jobs a good 'un:

If you're too aggressive removing the case, this is what happens, the clip on top snaps:

After several hours of fiddling in the dark, it's easy to be aggressive (or aroused, depends what/who you're fiddling I guess). The plastic actually has a small circular clip, which a metal arm in the car hooks into. As the motor rotates the plastic, it drives the metal arm. As mine had snapped, I've been geting cold air, but not from all the blowers.

@The_Judge_ I did the same, did you get the whole thing or just the white top bit?

Just the top white bit from what I remember, was a b*tch to put back ....
