Thanks be to anyone who can help.

My 87 GXL has a power window issue on the passenger side (Sluggish, barely rolls up and always requires being pulled up by hand). I cleaned the switches thoroughly, checked voltage at the connector to the motor (11.5 volts) and the window is still sluggish. ICEMARK mentioned in a thread somewhere that he very rarely sees the motors go bad.

Does anyone have any suggestions that I can try before I drop any coin on a new motor??

Thanks.

Voltage is pretty low at the connector, it should be 12.6 volts. Double check the lock out switch in the drivers door. The power for the passengers switch and motor are run from the drivers lock out switch and when it goes bad or gets dirty that will limit the power.

I checked that one first, but I will go through it tomorrow.

I need to see 12.6 volts in order for it to work correctly? I thought that I read between 9 and 12 would run that just fine? Or did I missinterpret?

Thank you for any guidance in this matter.

Clean the contacts in the switches with an electrical contact cleaner. The switch contacts like to carbon up on FB's

I will give that a go. I have cleaned both sides, cleaned a ton of carbon build up off of them, and that fixed the driver side, just not the passenger. Perhaps I need to do it again...

It will run actually down to about 8 volts, but anything less than 12.6 volts will reduce the speed. Toss lower than 12 volts in with old dirty window tracks (did you clean the window tracks?) and you have some pretty slow moving motors.

Yep. But double check the lock out switch on the drivers door switch. Again, that is where the passengers window gets it's power... NOT JUST THE SWITCH CONTACTS, BUT ALSO THE LOCK OUT SWITCH. 99% of the time, the drivers door power window lock out switch is what dirties up when the passengers window is slow.

I'd probably also clean the fuse box and circuit breaker connections (depending on year and model).
