M35 Drivers Window - Sickness Then Death

[MrStabby]

Drivers window has been playing up in that auto wind up would get to 2/3rds up, then reverse back down. Holding the button would make it power though with a tiny pause. Now the window is stuck at 1/3rd up and wont move in either direction. I guess the first step is to check all the fuses in the drivers side footwell - unless someone knows the right one. Anything else i should look at?

It will likely be the brushes in the window motor, I have had to change a few lately.

[MrStabby]

Ok - ill check the motor - how does the door handle come off? Do I lever off the faux wood trim to reveal screws?

[scotty nm35]

Yep, and the cover inside the door latch, you need to unclip the two plastic clips near the hinge, pull towards yourself, then slide the trim upwards.

See if there is a G35 clip on youtube, that will help.

[MrStabby]

Thanks - was easy once the door handle screws were revealed.

The 2/3rd up issue was a seperate issue for you. That is caused by it losing its programming for height. Once you remove the door trim if I remember rightly there was a black sticker around the centre of where the motor sits. If you remove that sticker it gives access to a button that allows you to program the height the motor goes up to. I can't remember the exact process used to program it. But I'm sure you will be able to work it out.

This needs to be added to the m35 über thread

My drivers window gets stuck at 3/4 also but makes a slipping teeth sound like the worm drive is shot. I check out my bushes and as Scotty mentioned they were also very worn. I bent them out so they contacted better and it fixed half the issue(new bushes would be better)...still need a new system I think.

[scotty nm35]

I have one new aftermarket window motor here, these are probably your best choice as most of the drivers window motors are flogged by this stage.

I have done the same a few times, cleaning the commutator and bending the brushes in will keep it going a few more weeks/months.

[MrStabby]

Everything's back together with a new motor from Scotty. However, when i open the door for step 6 of the reset procedure, there's no window movement so i'm guessing it hasn't taken.

I believe that the steps are for v35 g35 coupes as they drop the window partially when opening and closing as there is no door frame around the top of the glass
