Pinpoint Test C: A Single Power Window Is Inoperative - RH Front Window

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Use the correct probe adapter(s) from the Flex Probe Kit when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
  1. C1 CHECK THE RH FRONT WINDOW OPERATION FROM THE LH FRONT WINDOW CONTROL SWITCH 
    • Ignition ON.
    • Operate the RH front window from the LH front window control switch.
    • Does the RH front window operate from the LH front window control switch? 
    • Yes:  GO to C2  .
    • No:  GO to  C3.
  2. C2 CHECK CIRCUIT CPW14 (VT/WH) FOR VOLTAGE 
    • Ignition OFF.
    • Disconnect: RH Front Window Control Switch C604.
    • Ignition ON.
    • Measure the voltage between RH front window control switch C604-3, circuit CPW14 (VT/WH), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes:  INSTALL a new RH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
    • No:  REPAIR the circuit. TEST the system for normal operation.
  3. C3 CHECK CIRCUITS CPW20 (WH/OG) AND CPW19 (VT) FOR VOLTAGE AND GROUND 
    • Ignition OFF.
    • Disconnect: RH Front Window Motor C608.
    • Ignition ON.
    • Measure the voltage between RH front window motor C608-1, circuit CPW19 (VT), harness side and RH front window motor C608-2, circuit CPW20 (WH/OG), harness side while operating the RH front 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 - FRONT DOOR . TEST the system for normal operation.
    • No:  GO to C4  .
  4. C4 CHECK THE RH FRONT WINDOW CONTROL SWITCH 
    • Ignition OFF.
    • Disconnect: RH Front Window Control Switch C604.
    • Carry out the window control switch component test on the RH front window control switch.

      Refer to appropriate SYSTEM WIRING DIAGRAMS article for component testing.

    • Did the RH front window control switch pass the component test? 
    • Yes:  GO to C5  .
    • No:  INSTALL a new RH front window control switch. REFER to WINDOW CONTROL SWITCH . TEST the system for normal operation.
  5. C5 CHECK CIRCUITS CPW20 (WH/OG) AND CPW19 (VT) FOR AN OPEN 
    • Measure the resistance between RH front window control switch, harness side and RH front window motor, harness side using the following chart:
