Diagnosis And Testing - Window Smart Motor

When a window motor is installed, it must be initialized to program the up and down stops. The initialization procedure is to manually drive the window motor to both the top and bottom of the window travel. Initialization is performed by holding the switch for two seconds after the window reaches the full up position.

Diagnosing a motor concern requires the technician to diagnose by the process of elimination. If a window motor is inoperative, verify that all switch signals to the motor are correct. Verify power and ground at the window motor. If the switch signals, power and ground are okay and there are no obstructions, attempt to initialize the motor prior to replacement.
