I just bought a 02 pontiac montana off of an individual. While I was checking at the vehicle at my house I had the keys off and the doors open. I noticed a real loud noise from the back end, it sounded like some kind of gear trying to move. It does have one power door and rear air. Today when I had the key off I still heard the same noise. Anybody have any ideas what the sound might be? Also I noticed the back windshield wiper only moves partly. I had to turn it on and manually push it back down. Does anybody know if the motor is bad or what could be that problem also. Please help me with my newer vehicle.
