I am having issues with my back drivers side window now going back up at all. I get this loud humming noise when i try to put it back up. And the window will not even move. Does this sound like a motor or a regulator?
thanks

 

could be.... what year,trim etc. of car are we talking?

 

Honestly, it is for my girlfriends 04 jeep liberty. I have an 04 accord and I love this site but did not have the time or patience to join a jeep one

 

try cleaning the tracks first with a sponge, RUBBING alcohol (don't waste the good stuff, that's for afterward) and a roll of paper towels. A lot of times, the motor is not in great shape, but isn't burnt out yet and cleaning the tracks could get enough life out of it. When you are done cleaning, spray them with silicone lubricant spray.

 

Great, I will try that.
thanks

 

Also, once you press the switch for it to go up or down try pulling on the window and see if it will come up, if it's loose it's out of the track, if it comes up with help then it's a week motor, out of adjustment or really dirty tracks.

 

Yeah, it will not go up at all with any help. I had to take off the door panel and manually pull up the window to keep it up, and then taped the window to the door frame. So I wasn’t sure if it was the motor, or if it was off track, or the regulator (not sure what that does), or if I should just find a new girlfriend…maybe that would be easier.

 

was there resistance as you tried to pull the window up or did it just feel like you were lifting it? It's starting to sound like it fell off the track.

 

Well I don’t think there was a whole lot of resistance. If it was off track, is that difficult to fix on most cars?

 

nope, it's either off the track one or two different ways, if the glass actually fell out of the track then you want some "Gorilla Glue" or "Gorilla Snot" as some people call it to glue the window back in, if it's a case of the bolts coming out then you'll have to locate some replacements, in either case, pop the door panel off, locate the track (it's either a scissor lift or veritcal track) run the window motor up/down and try to locate what's moving and where.
