R34 Window Issue.

[Pure_Sincerity]

Hey guys, just recently my mate put my front passenger window down, but then when I went to put it up, it stops about 3" up and won't go any further, you can put it back down, but will always stop at that point when going up. I've pulled the door cars off and I cannot find anything stopping it.

Ideas ?

How does it stop? Abruptly like it's running into something or slows down and then stops? No obstructions up the top of your door where glass slides stopping it from going all the way up?

Is it catching on the rubbers? Quite often the windows sag inwards and ends up pushing on the seals. There are adjustable parts to the rails. Otherwise the motors could just be gone.

The window still goes freely up and down just till that point. Once it hits that point it just stops instantly, I've got the door card apart and silicone sprayed the tracks but still nothing and I can't see anything stopping it.

According to the R34 workshop manual, the power windows have a limit switch that senses excessive current draw, foreign objects etc. It states that any of the following could cause the window to stop "150mm" from the top of the window travel:

- Limit Switch (Faulty)

- Limit Switch (Out of Adjustment)

- Limit Switch Circuit

- Power Window Motor encoder

- Foreign objects in track

- Excessive abrasion and deformation on window seal, weatherstrip or track.
