power windows

dirver window was not working , i changed the motor and the mechinisam. it worked for 3 days , when the window went up the motor locked . we pulled everything out put all new stuff in. it worked for about 3 more days and did it again.

Check for power at the motor. Is there power? If power is present, verify ground is present at the motor. If you have both, then you have a bad/defective motor. After you install the new one, verify that once the window is up, the power shuts off. If the power stays on, it will burn the motor.
