Pinpoint Test E: A Single Power Window Is Inoperative - RH Rear Window

WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
  1. E1 CHECK THE RH REAR WINDOW OPERATION FROM THE LH FRONT WINDOW CONTROL SWITCH 
    • Key in ON position.
    • Operate the RH rear window from the LH front window control switch.
    • Does the RH rear window operate from the LH front window control switch? 

    Yes  : GO to E2.

    No  : GO to  E3.

  2. E2 CHECK CIRCUIT 170 (RD/LB) FOR VOLTAGE 
    • Key in OFF position.
    • Disconnect: RH Rear Window Control Switch C801.
    • Key in ON position.
    • Measure the voltage between RH rear window control switch C801-3, circuit 170 (RD/LB), harness side and ground.

    • Is the voltage greater than 10 volts? 

    Yes  : INSTALL a new RH rear window control switch. REFER to WINDOW CONTROL SWITCH  in this article. TEST the system for normal operation.

    No  : REPAIR the circuit. TEST the system for normal operation.

  3. E3 CHECK CIRCUITS 884 (YE/BK) AND 885 (YE/LB) FOR VOLTAGE AND GROUND 
    • Key in OFF position.
    • Disconnect: RH Rear Window Motor C803.
    • Key in ON position.
    • Measure the voltage between RH rear window motor C803-a, circuit 884 (YE/BK), harness side and RH rear window motor C803-b, circuit 885 (YE/LB), harness side while operating the right rear window control switch in the down then up positions.

    • Is the voltage greater than 10 volts in both switch directions? 

    Yes  : INSTALL a new window regulator and motor. REFER to WINDOW REGULATOR - REAR DOOR  in this article. TEST the system for normal operation.

    No  : GO to E4.

  4. E4 CHECK THE RH REAR WINDOW CONTROL SWITCH 

    Yes  : GO to E5.

    No  : INSTALL a new RH rear window control switch. REFER to WINDOW CONTROL SWITCH  in this article. TEST the system for normal operation.

  5. E5 CHECK CIRCUITS 884 (YE/BK) AND 885 (YE/LB) FOR AN OPEN 
    • Measure the resistance between RH rear window control switch C801-5, circuit 885 (YE/LB), harness side and RH rear window motor C803-b, circuit 885 (YE/LB), harness side; and between RH rear window control switch C801-2, circuit 884 (YE/BK), harness side, and RH rear window motor C803-a, circuit 884 (YE/BK), harness side.

    • Are the resistances less than 5 ohms? 

    Yes  : GO to E6.

    No  : REPAIR the circuit. TEST the system for normal operation.

  6. E6 CHECK CIRCUITS 884 (YE/BK) AND 885 (YE/LB) FOR A SHORT TO GROUND 
    • Measure the resistance between RH rear window control switch C801-5, circuit 885 (YE/LB), harness side and ground; and between RH rear window control switch C801-2, circuit 884 (YE/BK), harness side and ground.

    • Are the resistances greater than 10,000 ohms? 

    Yes  : GO to E7.

    No  : REPAIR the circuit(s) in question. TEST the system for normal operation.

  7. E7 CHECK CIRCUITS 316 (YE/LB) AND 317 (GY/OG) FOR AN OPEN 
    • Measure the resistance between LH front window control switch C508-6, circuit 316 (YE/LB), harness side and RH rear window control switch C801-1, circuit 316 (YE/LB) harness side; and between LH front window control switch C508-7, circuit 317 (GY/OG), harness side and RH rear window control switch C801-6, circuit 317 (GY/OG), harness side.
