Anybody else have a problem with the passenger side window motor.I've always had trouble with that side being slower than the driver side going up and down,and it's been replaced twice since I had the car(four years).Anything that can cause this?

 

i dont know why one side would be weaker than the other side but in general the motors suck..i hadnt heard of anyone having to replace them twice though...my passenger side is slower than the driver side too...dont know why

 

Anybody know if there is like a heavy duty motor or something you can buy.Our windows aren't exactly the lightest one s in the world.

 

I would check the guides to be sure they are lubricated and nothing broken or bent.

 

Like shoebox said, take off the panel and make sure the guides are cleaned and lubed.

I'm not sure what it is, but i have noticed in all 3 of my F-Bodis (all 4th gens) the passenger has always slowed down first (and was the first motor to get replaced). I'm not sure why that is, my friends with them have had the same experience. Maybe just a freak coincidence as there is no logical reason i can think of to cause the passneger to be slower (due to wearing out first)...the mechanics are the same.
