My drivers side front window wont roll up all the way without a lot of help. All the others work fine. Does this mean just the motor needs to be replaced? And is this the correct part? Just makin sure I've got it diagnosed correctly before shellin out cash.

Thanks.

 

Sounds like a bad motor or faulty wiring. Seems like the correct part but you should be able to just ask your auto parts store just to double check.

 

Do you hear the motor atleast trying to turn on? If so, then its not the motor it woudl be the regulator...If you dont hear anything at all...its the motor...also check fuses just in case

 

It will go up some and will need help after about half way. Some times it works all the way..usually after driving for a while after I've rolled it down.
