All teh others work fine. What should I check for?

Checck the switch contacts first, then the switches, & then I would check the motor.

Does it work from either the driver'* switch or the rear switch? Both? Neither?

If it'* one switch and not the other, it'* a switch. If it'* neither, it'* the regulator.

My drivers side rear window doesn't work either. It did once or twice, (once at night) and i had to push on it inwards to get it to catch. Otherwise the motor made this buzzing kinda sound like it was rubbing on glass. Most of the time both switches do nothing at all.

That'* mechanical binding. Remove your door panel, and grease the ways and guides.

i have the same problem with my passenger side front window. I have to smash the door panel for it to work. The regulator is probably on its way out. I think it just gets frozen from no use. Lately it has been fine.

Yea admin, both switches dont work. The regulator is in the door?

Yup. The window regulator is the motor itself. I can get you part numbers (need to know specifically which door, year, model). PM me, and when I get home, I'll look that up for you.

Is this for me? It sounded like the window pickup/attatchment wasn't hooked up right.

Would some nice bike grease be ok? The stuff is 100% waterproof. It'* sick actually.

Yup, yup. Make sure it'* not smelly.
