Glass, Frames and Mechanisms
Pinpoint Test G: A Single Power Window is Inoperative - RH Front, LH or RH Rear, Edge
Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information Electrical Diagrams.
Normal Operation
The RH front window control switch receives voltage from the accessory delay relay. The LH and RH rear window control switches receive voltage from the LH front window control switch when the window lock switch is set to the UNLOCK position. Ground is provided to the RH front, LH rear and RH rear window control switches from the LH front window control switch. Each window control switch transfers voltage and ground to their respective window motors. Window direction is controlled by reversing polarity of the voltage and ground circuits being supplied to the window motor.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- Window control switch
- Power window motor
