WINDOW SWITCH
DIAGNOSIS AND TESTING - WINDOW SWITCH
For switch testing, remove the switch from its
mounting, refer to Switch Removal. Using an ohm-
meter, refer to Window Switch Continuity Charts to
determine if continuity is correct (Fig. 2) and (Fig. 3).
If the results are not obtained, replace the switch.
The master window switch has an Auto-Down fea-
ture. Actuation of the master switch to the second
down detent position will move the drivers side win-
dow completely down. The electronic switch will
automatically disconnect the motor approximately 1
second after the window bottoms out. Failure of the
electronic switch to detect stall current, will cause
the switch to disconnect after approximately 15 sec-
onds of operation. The auto down function can be
canceled by any movement of the switch.
