Pinpoint Test E: A Single Power Window Is Inoperative, RH Front - Zephyr

WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
  1. E1 CHECK THE LH FRONT WINDOW CONTROL SWITCH OPERATION 
    • Attempt to operate the RH window using the LH front power window control switch.
    • Does the RH window operate when using the LH front power window control switch? 

    Yes  : GO to  E6.

    No  : GO to E2.

  2. E2 CHECK THE POWER TO THE WINDOW MOTOR 
    • Key in OFF position.
    • Disconnect: RH Front Window Motor C623.
    • Measure the voltage between RH front window motor C623-4, circuit SBB35 (BU/RD), harness side and ground.

    • Is the voltage greater than 10 volts? 

    Yes  : GO to E3.

    No  : VERIFY BJB fuse 35 (30A) is OK. If OK, REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.

  3. E3 CHECK THE RH FRONT WINDOW MOTOR GROUND 
    • Measure the resistance between RH front window motor C623-3, circuit GD139 (BK/YE), harness side and ground.

    • Is the resistance less than 5 ohms? 

    Yes  : GO to E4.

    No  : REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.

  4. E4 CHECK THE LH FRONT WINDOW CONTROL SWITCH-TO-RH FRONT WINDOW MOTOR FEEDS 
    • Disconnect: LH Front Window Control Switch C535A. Measure the resistance between RH front window motor C623-1, circuit CPW12 (GN/OG), harness side and LH front window control switch C535A-2, circuit CPW12 (GN/OG), harness side.

    • Are the resistances less than 5 ohms? 

    Yes  : GO to E5.

    No  : REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.

  5. E5 CHECK THE LH FRONT WINDOW CONTROL SWITCH 
    • Carry out the LH front window control switch component test. Refer to COMPONENT TESTING .
    • Did the window control switch pass the component test? 

    Yes  : INSTALL a new RH front window motor. REFER to GLASS, FRAMES AND MECHANISMS - EXPLODED VIEW, FRONT DOOR  and WINDOW REGULATOR AND MOTOR - FRONT DOOR . INITIALIZE the RH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.

    No  : INSTALL a new LH front window control switch. REFER to WINDOW CONTROL SWITCH . INITIALIZE the RH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.

  6. E6 CHECK CIRCUIT CBP02 (GN) FOR VOLTAGE 
    • Disconnect: RH Front Window Control Switch C604.
    • Key in ON position.
    • Measure the voltage between RH front window control switch C604-2, circuit CBP02 (GN), harness side and ground.

    • Is the voltage greater than 10 volts? 

    Yes  : GO to E7.

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

  7. E7 CHECK THE LH FRONT WINDOW CONTROL SWITCH-TO-RH FRONT WINDOW CONTROL SWITCH CIRCUITS 
    • Key in OFF position.
    • Disconnect: LH Front Window Control Switch C535A.
    • Measure the resistance between RH front window control switch C604-5, circuit CPW12 (GN/OG), harness side and LH front window control switch C535A-2, circuit CPW12 (GN/OG), harness side.
