Pinpoint Test F: The Power Sliding Window Is Inoperative

WARNING: This page is about a different car, the 2005 Ford Pickup. However, it is still accessible from the selected car via links, so may be relevant.
  1. F1 CHECK THE VOLTAGE TO THE POWER SLIDING WINDOW 
    • Key in OFF position.
    • Disconnect: Rear Window Adjust Switch C980.
    • Key in ON position.
    • Measure the voltage between rear window adjust switch C980-4, circuit 400 (LB/BK) harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes  : GO to  F2.
    • No  : REPAIR the circuit. TEST the system for normal operation.
  2. F2 CHECK GROUND TO THE REAR WINDOW CONTROL SWITCH 
    • Key in OFF position.
    • Measure the resistances between rear window adjust switch C980-3, circuit 57 (BK) harness side and ground, and between C980-5, circuit 57 (BK) harness side and ground.

    • Are the resistances less than 5 ohms? 
    • Yes  : GO to  F3.
    • No  : REPAIR the circuit(s). TEST the system for normal operation.
  3. F3 CHECK THE REAR WINDOW ADJUST SWITCH 
    • Key in ON position.
    • Connect a fused jumper between rear window adjust switch C980-4, circuit 400 (LB/BK) and C980-2, circuit 1941 (YE/LB) harness side; and between rear window adjust switch C980-6, circuit 1942 (RD/YE) and C980-3, circuit 57 (BK) harness side. The rear sliding window should open.

    • Did the rear power sliding window open and close? 
    • Yes  : INSTALL a new rear window adjust switch. TEST the system for normal operation.
    • No  : GO to F4.
  4. F4 CHECK CIRCUIT 1941 (YE/LB) AND CIRCUIT 1942 (RD/YE) FOR A SHORT TO VOLTAGE 
    • Key in OFF position.
    • Disconnect: Rear Sliding Window Motor C3145.
    • Key in ON position.
    • Measure the voltage between rear sliding window motor C3145-1, circuit 1941 (YE/LB) harness side and ground, and between C3145-2, circuit 1942 (RD/YE) harness side and ground.

    • Are the voltages greater than 10 volts? 
    • Yes  : REPAIR the circuit(s). TEST the system for normal operation.
    • No  : GO to F5.
  5. F5 CHECK CIRCUIT 1941 (YE/LB) AND CIRCUIT 1942 (RD/YE) FOR A SHORT TO GROUND 
    • Measure the resistance between rear sliding window motor C3145-1, circuit 1941 (YE/LB) harness side and ground; and between C3145-2, circuit 1942 (RD/YE) harness side and ground.
