Window Switch

1. Remove the switch to be tested. See WINDOW SWITCH  in REMOVAL & INSTALLATION.
2. Using an ohmmeter, test front switch for continuity. See Fig 1 .
3. If the proper results are not obtained, replace the front window switch. See FRONT POWER WINDOW SWITCH TEST  table for test results.
4. Test rear window switch for continuity. See Fig 2 .
5. If the proper results are not obtained, replace the rear window switch. See REAR POWER WINDOW SWITCH TEST  table for test results.

The power window master switch has a Auto-Down feature on both front windows. The switches equipped with 2 detent positions when actuating the power window OPEN. The first detent position allows the window to roll down and stop when the switch is released. The second detent position actuated an integral express roll down relay that rolls the window down after the switch is released. When the express down circuit senses stall current (window has reached end of down travel), the switch will turn current off to the motor. The AUTO feature can be cancelled by actuating the switch UP or DOWN while window is in motion. If the electronic circuit in the switch fails to detect a stall current, the auto down circuit will time out within 9 to 14 seconds.
