front window wont go up

FWIW, when my regulator failed, there was little to no movement of the glass when the switch was pressed.

i had the same experience with passenger door, it went down perfect but stuck to go up until i pulled it for 2 cm with scew driver and cutter -stupid me scratched the glass littel bit- then it worked fine up and down the whole way but not to the end buttom .. do you recommend after market regulators or its a must to buy OEM?

I am no professional, but I would go OE. It seems like many people have had bad luck with aftermarket or ebay regulators. There should be a few threads on aftermarket regulators going around where you can read opinions from people who have actually used them.

The left front window on my X5 is raising slow and sometimes stopping before it`s closed .

I checked out all connectors and the guide seals before I went as far as removing the door card .
everything looked to be in order . I suspected the motor at fault so I removed the regulator and motor .
I found a broken wire on the winding .the photo shows the broken wire on the rotor exactly as it came out of the stator . FYI the rotor unscrews from the gear housing .
I repaired the broken wire and refitted the motor but it made no difference .
many of the wires in the winding are scorched blue so a new motor is required .

Took it today to windows specialized, they said in normal situations the whole regulator should be changed, but they managed to rebuild the broken window holder and changed some clips and job was completed within 30 min and $50

Did my lock carrier and had the same problem. I let car run unhooked the switch's then hooked backed up while car was running windows work fine.

We got lucky, it was the trace in the bottom corner of the board, on the side of the relay that controls the upward direction of the motor! The reason it wasn't working is that the trace on the board is really small, and it had corroded enough that it esentially had no conductivity anymore. All we had to do was solder a little "jumper" wire from the node where the trace began to the next component. Here is a picture: http://s15.photobucket.com/albums/a3...6-51-50_97.jpg

Are you good with electronics/have access to a multimeter? I am guessing that your problem is exactly the same as mine, since we both lost the same half of the window's functionality. It's worth a shot better than paying $165+ for a new window switch right?!

Let me know if you have more questions!

on receiving the above message the first evening that i got the chance I set about trying the fix. I removed and dismantled the window switch. I could see a slight flaw in the print but nothing that would make one suspicious of any shorts in the circuit especially as I do not yet posess a magnifing glass. I took out my multimeter and sure as hell the short shows up. As you can see from the photo below fitting of the red jumper wire has sorted the window switch. I now know that my problem never was the regulator or the motor.

Now on to the next problem. My passenger door is now stuck shut, unopenable from the outside and inside



Many thanks to aweber05

So had you since replaced the regulator or switch and resolved the problem? I am wondering if you replaced the regulator and if so, whether that fixed things or if you tried a new switch instead or this rewiring fix was your ultimate solution.

Ah, I missed your post #14 detailing the new regulator did not fix the problem.

Thanks for sharing another angle of our dreaded window problems.

I believe I have replaced 6, possibly 7, regulators.

i never would have found this solution myself. To look at the circuit board you would have no idea.
