GU Drivers window goes down by itself!

[mudski]

Yes its kinda weird. I pull on the door switch to close the window. The window goes up, and when it reaches the top, it goes back down a 1/4 of the way. Dunno if its the switch or what. Everything else works perfect just this. I honestly don't remember this happening before, so it may be normal. You know when you don't realise something has been happening for yonks then all of a sudden your like huh! Never noticed that before.

Have you taken the door trim off and tried it? Is it just falling back down?

After it comes Down are you able to put it back into place and it stays?

Make sure the window is not binding or getting caught on anything as it goes up.

Lube the window rubbers and runners.

There is a safety feature for the drivers electric window that will cause the window to stop from going up and come down by about a third if there is an extra amount of load put on the electric window motor.

I think it's a safety feature for the auto up to prevent kids from getting their hands or head caught in the window.

its a bit like a yo yo sometimes but I can live with it

Not falling mate. If I pull the switch half way it will go up and stay up. Its the auto part, when you pull the switch right up.

That must be it. I did replace my bailey channel on that door and while trying to get the reg out I had to wind it up( I think it was) and the reg wound out too much. So I plugged it in and fixed that. Worked for months after until as of late...
I had forgotten about that...
Now just how to work out how to fix it...

I'm not sure if there is a relearn procedure or not. I will have a look for you.

You need to make sure the window is not binding as it goes up.

I couldn't find any sort of relearn procedure.

I would start by removing the door trim, make sure all mounting bolts for motor and runners are tight, give it a lube up and adjust the runners and see if you can get the window to move more freely.

as a windscreen fitter....
wind window up fully using only manual.....youknow....tweak it up gradually.....
hold down button fully until window is fully down, continue holding 10 seconds
pull up on switch until window is up fully, continue holding up for 10 seconds
should reset upper and lower limits.
What is happening is callled a pinch reset. It is common when a window is broken OR... force is used to stop a window winding up....such as a fat arm or maybe a baby's head....

if this very basic reset doesnt help then take it back to the dealer. they can reset or do they're voo-doo magic on it.
pinch resets can be a pain in the arse and after glass reinstalled, best left to the dealer as it involves the computer.
