PX429

Hey guys, I have an SN95 and my passenger side window will sometimes go up, but will easily go down. I replaced the motor about a year ago , so I ruled that out. I've switched all the switches around so that's not it. If it press up on either the driver side or the passenger side i hear a click and the lights dim but the window does not move. if i press down it goes down with ease. after about 40 minutes the window will go up.

any ideas?

Thank you in advance!
