03 cavalier wiper on driver side is out is it fuse or motor?

You need to remove both the wiper arms. Take off the rain seal from under the windshield. remove the cover underneath you will find the rod has worn and dropped off you must get a complete new mechanism. Or if you cant afford to do that re attatch the rod to the buckle pin on the wiper arm and use some insulation tape to make a temporary repair till you can get a new one.

Idoubut it's a fuse.. Try to move yhe wiper up without forcing it. If it feels loose it might be disconnected from the wiper motor. If it won't move freely, the wiper motor may be at falt. If you have tried to assist it, was there and indication the wiper was tryying? There is a remote chance the linkage has come disconnected. ... good luck ... try to help it with a little lift, sometimes they hang up if not used for extended periods.
