Test C: A Single Power Window Is Inoperative - RF
PINPOINT TEST C: A SINGLE POWER WINDOW IS INOPERATIVE - RFNormal Operation
Under normal operation, the RF power window motor microprocessor receives power at all times through circuit SBP04 (GN/RD) and from the accessory delay relay through circuit CBP41 (BU). Ground is provided at all times through circuit GD138 (BK/WH). The master window control switch or passenger window control switch provides a voltage input to the power window motor microprocessor through circuit CPW19 (VT) to operate the RF window down, and voltage input through circuit CPW20 (WH/OG) to operate the RF window up.
This pinpoint test is intended to diagnose the following:
- Fuse(s)
- Wiring, terminals or connectors
- Window control switch
- Front door window regulator motor
