Passenger side power window stopped working?

Post by premier72 »

I have a 89GT and yesterday the window on the passenger side stopped working when I hit the switch? Anyone else ever had this happen?

I'm sure others have had a similar issue... these cars are getting quite old... But to start I would check the fuse, if its only one window then I would go directly to the switch to see if you can pop it out and test it to ensure its making a connection. I don't have power windows myself but thats where I would start to try and eliminate the window motor from the equation.

If not the fuse or the switch, the motor has an overload circuit in it that fails. Ive had it happen in both my 90's GM mini vans.
One on the drivers side the other on the passenger side. If you window goes down but not up and if trying to go up,
it goes a bit then stops, then after awhile it'll go up a bit again. It is that overload device.
You can replace the motor which is a lot of work or try the bypass method below.
The fix is to use a multi tap on the positive wire to the motor, with the new positive wire from the tap, put on a connector with a hole for a screw.
Then put a sheet metal screw with the connector under it into the test hole on the bottom of the motor. If the screw is long enough to make contact with whats inside, you have now bypassed the overload. You might want to install the smallest possible fuse so you don't burn out the motor if you hold the button too long.
