Its has to be either the regulator or the window motor

Does the motor run with out the window moving? If that's the case you have a problem with the regulator. It may be a simple clip with a roller on it. I haven't worked on this model lately but I think that's the way it's set up. It is quite complicated to remove the regulator to replace the clip but the part is only about $10.00.


If you don't here the motor run when you try to roll the windows up I would suspect the master switch in the drivers door, In the off position it should send a ground to both wires for all four windows. when you push either switch the ground is switched to power and completes a circuit to move the window. If only 1 wire has a ground at each motor when the switches are off you have a bad switch. This will cause the window to work only one way.


If the window tries to go up but you need to help pull it up the motor is either week or the window is binding. Try lubing the track the window goes in with a dry lubricant like a Teflon based lubricant you should be able to find something like that at a good auto parts store. If that doesn't fix it you will need to try adjusting the tracks and you may need to replace the motors.
Reply:you might want to try unhooking the vehicle battery for a few minutes. 2001 devilles use individual door control modules, the switches are only an input to the door modules which run the motors. i have seen these symptoms be created by a weak battery that causes a software lock-up in the module. unhooking the vehicle battery usually clears the issue. this is assuming that you prove it is not a regulator issue. these are also known to fail.
