02 grand prix power driver window wont roll up....only down

SOURCE: passenger side window

it could be a bad swich on the passenger side because they comunicate each other, or sometiems the wiring brake just by the door where all the wiring goes to the boddy you need to open the black hose with a nife and look for broken wiring circuits

There is a heater resistor module, it is located on the passenger side under the dash by the blower motor. It is a bit tricky to get to but isnt to hard to replace. I just dealt with this issue in May. The unit cost me about 86 dollars from the dealer. But be careful becuase normally the resistor goes due to a short in another component in the syste, so this may not be the complete fix for you. My main culprit ended up being the blower motor.

Good Luck

sometimes its behind the alternator real close to the firewall. Find the bigger of the two hoses and pipes the low side is always bigger. Also the cap is blue and the fitting for the charging can will only fit on the right valve.

Unless the motors were replaced at one time, the only bolts holding the window to the regulator are at the slides. any hardware that fell apart should be inside the bottom of the door. Panel removal is pretty simple..only hidden fastener is on the edge...small reflector has one under there.
Haynes makes a good reference for that car for about $20.

Most often on those the motors are shot. as soon as they are activated they overheat and slow down or stop. Only way I know of to repair is to replace them. You will need a manual to do this or do them one at a time so you can check how it goes back together by looking at other one. Motors are riveted in and need to be drilled to remove...use small bolts to re-attach.
I've seen motors online for about $30-40 each.
