I recently bought a new window motor regulator for the passenger side of my 02 Durango thinking that would solve the problem. I attached everything and the window went down but will not come back up? Now the two back window switches will not work even though they worked a week ago, but when I hit a bump the switches will work but when I hit another the switches turn off? So I'm just wondering if anyone has experienced this problem? And knows how to fix it? Oh and master switch controls both back windows but not the passenger.

 

Sounds like a bad connection somewhere. All the window switches have to go through the driver's master switch to work, so I'd check it first.
