Motor Test
- Remove the driver's door panel (see FRONT DOOR PANEL REMOVAL/INSTALLATION ).
- Disconnect the 2P and 4P connectors from the window motor.
- Test the motor in each direction by connecting battery power and ground according to the table. When the motor stops running, disconnect one lead immediately.
- If the motor does not run or fails to run smoothly, replace it.
- Pulser Test
- Reconnect the 4P connector to the window motor.
- Check for voltage between the terminals.
- There should be battery voltage between the B4 (+) and B2 (-) terminals when the ignition switch ON (II).
- Connect an analog voltmeter between the B3 (+) and B2 (-) terminals, and run the window motor at down or up. The voltmeter needle should move back and forth alternately (a digital voltmeter should show the average voltage between 0-5 V).
- Connect an analog voltmeter between the B1 (+) and B2 (-) terminals, and run the window motor at down or up. The voltmeter needle should move back and forth alternately. (a digital voltmeter should show the average voltage between 0-5 V).
- If the test is not as specified, replace the driver's window motor.
