Driver's Power Window Motor Test
Motor Test
- Remove the door panel (see FRONT DOOR PANEL REMOVAL/INSTALLATION ).
- Disconnect the 6P connector (A) from the power 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 the driver's door regulator (see FRONT DOOR GLASS AND REGULATOR REPLACEMENT
).
Hall IC Unit (Pulser) Test
- Reconnect the 6P connector to the power window motor.
- Measure the voltage between the terminals.
- There should be battery voltage between terminals No. 6 (+) and No. 5 (-) when the ignition switch is ON (II).
- Connect an analog voltmeter between terminals No. 3 (+) and No. 5 (-), and run the window motor 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 terminals No. 2 (+) and No. 5 (-), 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 voltage is not as specified, do the power window master switch input test (terminals No. 4, No. 6 and No. 17) (see POWER WINDOW MASTER SWITCH INPUT TEST ).
- If the switch test is OK, replace the power window motor.
- Reset the power window control unit (see RESETTING THE POWER WINDOW CONTROL UNIT ).
