Just changed the drive side motor assembly a couple of weeks ago.
Not hard to change out. Took me a few hours

 

I had the same issue but the driver side, well it worked for a second then it would slow down and stop, now it wont work at all. took the panel off (carefully, the clips may break if.when you do it, but just put them back on the panel) and the motor is right there at thebottom, the thing is, these oddly looking motoros have cables running on them, im trying to figure that part out, but when i put pressure on the motor the windows goes up and down just fine. strange isnt it.. ? try that see if it works.

 

How did you take the cables off? from the door, or motor? that th part im not getting. i wish there was a video on this or pictures

 

replace the whole regulator assembly

Here's one for you. I was at the Dealer yesterday on another issue, and mentioned the inop. window on the pass front door, the service tech walked around to the door, opened it and slammed it hard, reopened it, pushed the button, and what do you know, it went down and up and down and well you get the idea. He said this happens a lot in Florida because of the heat. The window seal soften and holds the window up. Go figure .
