Rear Window is Stuck in Down Position :/

Dunc · June 3, 2017

Does anyone know the part number for the rear left window regulator? The part number I found, 23274600, says that it is discontinued and does not tell me what replaces it.

Came home last night from work with the windows down only to find that I couldn't roll them up again. I can hear the switch clicking so I know it has 12v, but the click isn't as "strong" as a click as the other windows. I'm guessing it's either the motor or the regulator but since the regulator includes the motor and isn't much more I'll just do that and replace both...if I can find the part.

It's pretty irritating that it's even having a problem. Being a '15 and hardly ever using the windows there is zero reason this should be an issue. I'll be taking the door panel off today to try and at least get it up again until I can find parts. Thankfully the rain isn't supposed to come for another day otherwise I would have been really pissed.

84043806. Are you out of warranty? If you still have 3/36 you should be covered.

Thank you. Yes I am out of warranty. I just started the car to go pick it up from the dealer and the window rolled up & down like normal. Wtf?

So new question: my driver's side headlight has been acting up and not firing up. I have done a retrofit and was going to look into the ballast being the issue. I just haven't taken the time to diagnosis the exact issue. Is there some strange thing with these cars that if the headlight has a problem that the rear window wouldn't roll up? I wouldn't think that would be so because that's a really bad idea. I ask because I vaguely remember on my Jeep that when I had a problem with the AC (or something like that) that the rear passenger window would auto roll down when you started the car, but you could still roll it back up again. It was apparently Chrysler's way of saying "you have a problem."

I'm at a loss now why the window would all of a sudden work again after just sitting overnight.

I would think that they are two isolated issues.

When the window didn't work, did you try both the switch on the rear door and the corresponding one on the driver's door? Just a thought...

I think so as well but figured it was potentially connected somehow. I just messed with it and flipped the relays. The relay from the passenger side fired the non-working driver's side. So for now I'm thinking that was just the relay...until it acts up again then I'll look closer at the ballast. The wiring harness I made isolates each side as their own circuits, but they share common +/- connectors at the battery with problems like this in mind when I made it so I wouldn't be completely without light if something happened.

Only problem now is that I dropped a 10mm wrench and a bolt down in the front end and can't find it. Looks like I get to take the whole front end apart now
