Normal Operation
The RH rear window control switch receives voltage from the LH front window control switch when the lock-out switch is in the UNLOCK position. Ground is also provided to the RH rear window control switch from the LH front window control switch. The RH rear window control switch transfers voltage and ground to the power window motor. Window direction is controlled by reversing polarity of the voltage and ground circuits being supplied to the power window motor.
When operating the RH rear window from the LH front window control switch, voltage and ground is sent from the LH front window control switch through the normally closed contacts within the RH rear window control switch. Window direction is controlled by reversing polarity of the voltage and ground circuits being supplied to the power window motor.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Window control switch
- Power window motor
