Power window won't go up or down. - 1999 Pontiac Grand Am GT

Sounds like you have issue with the push button controls for the window. I really don't think I had to say it. If you remove the door panels and check it out you may find, rust broke wires, bad connection some simple problems which need a better visual look. If a window goes down but not up. It should not be a fuse, relay or power issue unless the connection is a problem.

didnt specify vehicle -generic answer -pop out switch and test for power and operation if no power to switch will need to check harness -if power to but not after switch replace switch--good switch will need to remove door panel and test window motor /egulator

You can remove the door handles and power window switches and the screws in the door pad and push up on the pad and it will come out of the track and then you can see the motor and replace the part yourself. Hope this helps.

Window motors bad but if you do end up replacing it, first check for power at the plug going to the window motor when you use the switch.

try window motor and window controls

Hi
it happen with me also actually the problem is the power window get jammed from the inner part..... you if you able to open it just open now clean it well then spray the lube into it and for a long time it work properly..... thankyou

make sure power windows lock out switch on driver side not on position, that will cause power windows not work or you have faulty power window relay.

Check fuse, try switch from other window as they do the same thing. You may need to remove the trim & power the window up manually to check motor works.

You will need to remove your interior trim panel and check your window regulator for damage and for power going to your window motor. If your regulator is ok and you have power going to the motor then you have a bad window motor. If there is no power at the motor then you will need to check the circuit for the problem ie. blown fuses, broken wiring, bad switch. It is very commen for the motors to go bad. Good luck.
