Window Regulator?
Hey, what's up guys,
so was driving the other day with the windows cracked and went to put them up and the rear pax would not raise. I made mistake of cycling it and it would go down but not up. finally once all the way down I was stuck at a light and tried it and it went up. I thought. Was looking at the car today and realized there is a tiny space between the window and being fully closed. So I tried to raise with door switch. Nothing. Went to the actual door and tried that, nothing. I am guessing maybe the window regulator but open to other suggestions as to the culprit?

There’s a procedure to reset the windows. Try that first.

Not sure if the reset procedure works for the rears, but it has to be done from the door itself. Sounds like you are doing it from the front door, am I right? Maybe the switch in the front door is malfunctioning if the window open/closes using the switch on the door itself.

it's weird because earlier in the day, when I first saw it cracked, I tried the driver door, then went to the back door panel and tried to raise it with no success. I did NOT cycle it down or at that point know your 10 second procedure so no, I didn't try that on the door panel yet. Once I got it to come fully up yesterday I have not messed with it again.
