Driver's side window sticking
 

Tried to roll my driver's side window down today and it got stuck. Then it wouldn't come back up. Kept trying and it would go down but not back up. Not sure how, but I eventually coaxed it into coming up, and left it like that.

Figuring I'll tear into the door soon. I'll be following the FSM. Any tips before I get cracking?

Does it make a loud grinding noise when it gets stuck?

Not as far as I heard. There was traffic around me during the events I described above, and I haven't tested it since because I have a lot of driving to do in the next few days and don't want to be stuck with a window that won't close. Would it have been loud enough to be heard over mild engine noise (from me) and tire noise (from other cars)?

One common failure mode is for the plastic gears inside the window lift motor to strip, which means the window randomly stops when the gear gets to the stripped part and makes an awful grinding noise. You would have heard it. Doesn't seem like this is your issue but I've replaced the motors on both passenger and driver side.

Yeah, I hope it's not that. Guess we'll see.

Kills me that this had to happen when it did. Nothing but great windows-down weather these days, and I don't think I can even touch this until Sunday. :(

Had to abort the diagnosis because of time constraints. Made a video, though. Does this seem like a motor problem?

Not sure about the s2, but on the S1 you can just replace the window regulator gear. They are under $10 and I recommend buying two just in case your other window starts acting up later.

Yup, it was the motor! FWIW.

I'm having a bit different window problem...drivers side operates fine except when rolled all the way up it makes a loud clicking/grinding sound. It almost acts like it doesn't know its already rolled up and trying to keep rolling up...if that makes sense?

would this be caused by the motor or regulator?

Thread ressurection. Does anyone have any experience with this specific issue? Mine is now doing the exact same thing described here out of nowhere. Grinding when the window gets to the top.

Amusingly, I just had my car at the stealership for a compression test and asked them to look at my window, which is doing the same thing. Their diagnosis is bad teeth on the motor gear, therefore motor replacement. They wanted $500 parts and labor to do it. Worst case scenario is regulator and motor replacement. Best case scenario is gear repair kit. Here are the parts:

I replaced the motor a while back (2 years ago) I had no problem. I purchased both the motor and the gear. The gear ended up being what was broken but it was a little bit of a pain to get to it. If I had to do it again I'd probably just do the motor as its a lot faster and not worth it if you don't have want to struggle and want to do it quickly. but you save 30 bucks if you do just the gear....

I went ahead and replaced the whole motor unit, which did solve my problem. BTW, the Dorman part has all the exact same markings as the OE part; it is the OE part.

Thank you for the info good sir.
