Pinpoint Test B: A Single Power Window is Inoperative - Passenger Front
Refer to Wiring Diagram Set 100, Power Windows for schematic and connector information. Diagrams By Number
Normal Operation
During normal operation, battery voltage is provided to the passenger power window motor at all times through circuit 2033 (BN/LB). When the accessory delay relay is active, the passenger power window motor receives voltage through circuit 170 (RD/LB) and the passenger front window control switch receives voltage through circuit 984 (YE/LB). Ground is provided to the passenger power window motor through circuit 1205 (BK). Pulling the driver or passenger window control switch up provides voltage to the window motor through circuit 313 (WH/YE) to command the window up. Pressing the driver or passenger window control switch down provides voltage to the window motor through circuit 314 (TN/LB) to command the window down.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Driver window control switch
- Front passenger window control switch
- Front passenger window motor
