Passenger Door Power Window Switch
3. Test passenger door switch for continuity as described.
4. If the results are not OK, replace the switch. The power window master switch has a Auto-Down feature. The switch is equipped with two 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 actuates an integral express roll down relay that rolls the window down after the switch is released. When the express
down relay senses an amperage spike (motor pushing against down stop) in the feed circuit, current is turned off to the motor. The AUTO feature
can be cancelled by actuating the switch UP or DOWN while window is in motion. Failure of the electronic switch to detect an amperage spike
will cause the switch to disconnect after approximately 11 seconds.
