I need a wiper motor/wiper motor assembly that will fit a 79 Blazer! The motor is dying in mine, it will run for 5-10 minutes, get jerky, then stop in the middle of the windshield! It is getting dangerous to drive in the rain, and I can't afford a new one. It sucks to have to pull over and wait for half an hour for the motor to cool off/unstick if its raining real hard!
