Pinpoint Test D: A Single Power Window Is Inoperative - LH Rear Window

WARNING: This page is about a different car, the 2008 Mercury Mariner and 2008 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
  1. D1 CHECK THE LEFT REAR WINDOW OPERATION FROM THE LH FRONT WINDOW CONTROL SWITCH 
    • Key in ON position.
    • Operate the LH rear window from the LH front window control switch.
    • Does the LH rear window operate from the LH front window control switch? 
    1. YES  : Go to  D2.
    2. NO  : Go to  D3.
  2. D2 CHECK CIRCUIT CPW14 (VT/WH) FOR VOLTAGE 
    • Key in OFF position.
    • Disconnect: LH Rear Window Control Switch C701
    • Key in ON position.
    • Measure the voltage between LH rear window control switch C701-3, circuit CPW14 (VT/WH), harness side and ground.

    • Is the voltage greater than 10 volts? 
    1. YES  : INSTALL a new LH rear window control switch. REFER to Window Control Switch . TEST the system for normal operation.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  3. D3 CHECK CIRCUITS CPW21 (BN) AND CPW22 (GN/VT) FOR VOLTAGE AND GROUND 
    • Key in OFF position.
    • Disconnect: LH Rear Window Motor C703
    • Key in ON position.
    • Measure the voltage between LH rear window motor C703-1, circuit CPW23 (GY), harness side and LH rear window motor C703-2, circuit CPW24 (WH/VT), harness side while operating the LH rear window control switch in the down then up positions.

    • Is the voltage greater than 10 volts in both switch directions? 
    1. YES  : INSTALL a new window regulator and motor. REFER to Window Regulator - Rear Door . TEST the system for normal operation.
    2. NO  : Go to  D4.
  4. D4 CHECK THE LH REAR WINDOW CONTROL SWITCH 
    • Key in OFF position.
    • Disconnect: LH Rear Window Control Switch C701
    • Carry out the Window Control Switch component test on the LH rear window control switch. Refer to appropriate COMPONENT TESTING article.
    • Did the LH rear window control switch pass the component test? 
    1. YES  : Go to  D5.
    2. NO  : INSTALL a new LH rear window control switch. REFER to Window Control Switch . TEST the system for normal operation.
  5. D5 CHECK CIRCUITS CPW23 (GY) AND CPW24 (WH/VT) FOR AN OPEN 
    • Measure the resistance between LH rear window control switch C701-5, circuit CPW24 (WH/VT), harness side and LH rear window motor C703-1, circuit CPW24 (WH/VT), harness side; then between LH rear window control switch C701-2, circuit CPW23 (GY), harness side, and LH rear window motor C703-2, circuit CPW23 (GY), harness side.
      • Fig 3: Measuring Resistance

    • Are the resistances greater than 10,000? 
    1. YES  : Go to  D7.
    2. NO  : REPAIR the circuit(s) in question. TEST the system for normal operation.
  7. D7 CHECK CIRCUITS CPW15 (YE)/CPW17 (BN/GN) AND CPW16 (BU/OG)/CPW18 (GY/VT) FOR AN OPEN 
    • Disconnect: LH Front Window Control Switch C504b
    • Measure the resistance between LH front window control switch C504b-1, circuit CPW15 (YE), harness side and LH rear window control switch C701-1, circuit CPW17 (BN/GN) harness side; and between LH front window control switch C504B-6, circuit CPW16 (BU/OG), harness side and LH rear window control switch C701-6, circuit CPW18 (GY/VT), harness side.
      • Fig 5: Measuring Resistance
