I drive a 2002 Ford F150 4x4 and the driver's side window takes longer to go up than the passenger side window. It goes up, but it takes about 10 seconds longer to go up than the passenger side's. Any possible reason why or should I just suck it up and wait the extra 10 seconds?
My 97 does the same thing on the drivers side..kinda slows right down to an almost stop about halfway up. Motor probally going bad...Ill get to that after I resolve my EGR issues.
on mine if I spray wd40 down the tracks from above, it lets the window speed up for a month or so. I have tried greasing the tracks behind the door panel. I may try one last time with silicone grease along the vertical tracks
it is slow because the window is dragging in the track. the motor is overloading. if you dont fix it the motor will burn up. take off the door panel. rub grease in the slotted track and the wheels running in the track (front to back). spraying the window channel with silicon will help free some things up, but the root cause is probably the motor arm- window steel track and rollers. i sprayed with WD40... did not doo much, then rubbed grease on the slide and z-rails and pins and worked it back and forth. runs 3 times faster now, and lasted for over a year now.
