PASSENGER WINDOW

1992 Pontiac Grand Prix • 6 cylinder • 170,000 miles

My automatic window in my passenger door will roll down but will not roll up. I was thinking it is the regulator but the window is not fallin farther down.

It look's like there is a ball socket on the end of the arm on the regulator that slide's in a channel on the base of the window. On the the right side of the base of the window you will see the cut out where the ball can slide out.

Ok is there a screw in there? Or does it just pop out?

It looks like it just pops out I only have a diagram to go by with a car that old the info is limted on my online repair manual.

Ok I will take a look, hopefully it just pops out or is easy to figure out. I talked to the previous owner, he says that is has happened before that after awhile it just goes back up. Could that mean that maybe there is something else wrong?

No usually if your getting power and ground to the motor the possible cause's are a binding glass bad or weak window motor or a binding regulator.

Ya we cant even get the ball socket to budge. Is it possible that it is the motor? Even though we are gettin power could it still be that the motor is jammed or fried I guess you could say.

Yes it's very possible you could have a bad window motor if your getting power and ground to the motor and nothing is moving then more then likely you have a bad motor or a bound up regulator/window glass. Since you already tried helping the window up by grabbing the glass I guess it would be safe to say you don't have a bound up window glass. You will have to undo the window regulator and slide that ball out of that channel and see if the arm move's at all.

Hey I'd like to get a piece of this guys (though the thread is a year old : -). I'm having a similar problem with my passenger window on my 92 Grand Prix LE. I seem to remember that if someone closed the window too high (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 something with a finger on the down button. Not opening this window. I've checked voltage at the motor and do have 12v on the blue wire 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 but I guess if it comes to that. In the meantime, how might I check the '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.
