I just finished installing my second replacement window motor and I'm running into the same problem once again. The first motor and reg worked for a week or so then started going slow and eventually stopped going up. This one looks like its on the same path already and its day 2. I have greased up the tracks and loosened the front track still same problem. Is there something else ,electrical wise that can be the culprit. thanks

 

Well you dont grease up the tracks. You use some speacial silicone spray. I hope thats what you used. If not that would explain the sticking..

 

Did you replace the regulator as well as the motor? I replaced my back two regulators and motors because the plastic piece that attaches the window to the regulator. Haven't had any problems. I would test the motor to see if thats what is preventing it from working. If so, where are you getting the motor from?
