My window on the passenger side is really dragging going up and down.Barely moving.Do I need to think about replaceing the motor? I moistened the glass and that didn't help.1994 Dakota v8 SLT,160,000 miles.

 

Lubricate the window channel. My local dealer used a tube of speedometer grease to do this. Tech just squirted into channel on both sides of door & after running up & down a few times cleaned excess grease off window-15 years ago, still no problem. YMMV

 

+1 to lubing the channel also check the clips on the backside of the window(they run in thechannel to keep the window straight) i had some fail on my once. if those chack out then i would lube the arm then look at the motor.
