Hello, I'm having a problem with my 1992 Grand Prix LE passenger front power window. I seem to remember that if someone closed the window too high in the past (kept their finger on the up button once the window was closed), it would bind up and the window wouldn't work afterwards. To clear this, you could usually go over railroad tracks (or bumpy road) with a finger on the down button and the drivers window would start working fine until it happened again - my son used to do that when he drove the car until I got it into his head what was going on. That trick isn't working to open this window - passenger front.
I've checked voltage at the motor and do have 12v on the blue wire when depressing the switch but haven't tried grounding the other wire (brown) yet as I've looked for a wiring diagram. I'm not anxious to drill out the rivets to replace the motor but I guess if it comes to that.
In the meantime, how might I check the window 'regulator'? I don't know much about how these regulators interact with the motor and am anxious to learn more. I'm trying to get this car going again after a couple of years in storage as it waited for my daughter to turn 16. Thanks for any help.
