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

WARNING: This page is about a different car, the 2008 Mercury Sable, 2008 Ford Taurus X, and 2008 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
  1. C1 CHECK THE RH FRONT POWER WINDOW MOTOR 
    • Disconnect: LH Front Window Control Switch C504a and C504b
    • Key in ON position.
    • Connect a fused jumper wire between LH front window control switch C504b-1, circuit CPW13 (BN/YE), harness side and LH front window control switch C504a-5, circuit CBP47 (GN/BU), harness side. Connect a second fused jumper wire between LH front window control switch C504b-5, circuit CPW12 (GN/OG) and LH front window control switch C504b-4, circuit GD133 (BK). The RH front window should operate in the up direction.

    • Connect a fused jumper wire between LH front window control switch C504b-5, circuit CPW12 (GN/OG), harness side and LH front window control switch C504a-5, circuit CBP47 (GN/BU), harness side. Connect a second fused jumper wire between LH front window control switch C504b-1, circuit CPW13 (BN/YE) and LH front window control switch C504b-4, circuit GD133 (BK). The RH front window should operate in the down direction.

    • Does the RH front window operate correctly? 
    1. YES  : Go to  C2.
    2. NO  : Go to  C4.
  2. C2 CHECK CIRCUIT CPW14 (VT/WH) FOR VOLTAGE 
    • Key in OFF position.
    • Connect: LH Front Window Control Switch C504a and C504b
    • Disconnect: RH Front Window Control Switch C604
    • Key in ON position.
      NOTE: Be sure the window lock switch is set to the UNLOCK position.
    • Measure the voltage between RH front window control switch C604-5, circuit CPW14 (VT/WH), harness side and ground.
      • Fig 3: Measuring Voltage

    • Is the voltage greater than 10 volts? 
    1. YES  : Go to  C3.
    2. NO  : REPAIR the circuit. TEST the system for normal operation.
  3. C3 CHECK THE LH FRONT WINDOW CONTROL SWITCH 
    • Key in OFF position.
    • Disconnect: LH Front Window Control Switch
    • Carry out the LH Front Window Control Switch Component Test. Refer to appropriate COMPONENT TESTING article.
    • Did the LH front window control switch pass the component test? 
    1. YES  : Go to  C4.
    2. NO  : INSTALL a new LH front window control switch. REFER to Window Control Switch . TEST the system for normal operation.
  4. C4 CHECK THE RH FRONT WINDOW CONTROL SWITCH 
    • Carry out the RH Front Window Control Switch Component Test. Refer to appropriate COMPONENT TESTING article.
    • Did the RH front window control switch pass the component test? 
    1. YES  : Go to  C5.
    2. NO  : INSTALL a new RH front window control switch. REFER to Window Control Switch . TEST the system for normal operation.
  5. C5 CHECK CIRCUITS CPW13 (BN/YE) AND CPW12 (GN/OG) FOR AN OPEN 
    • Measure the resistance between RH front window control switch C604-1, circuit CPW13 (BN/YE), harness side and LH front window control switch C504b-1, circuit CPW13 (BN/YE), harness side.
      • Fig 4: Measuring Resistance
      GF0016488Courtesy of FORD MOTOR CO.
    • Measure the resistance between RH front window control switch C604-6, circuit CPW12 (GN/OG), harness side and LH front window control switch C504b-5, circuit CPW12 (GN/OG), harness side.
      • Fig 5: Measuring Resistance
      GF0016489Courtesy of FORD MOTOR CO.
    • Are the resistances less than 5 ohms? 
    1. YES  : Go to  C6.
    2. NO  : REPAIR the circuit(s). TEST the system for normal operation.
  6. C6 CHECK CIRCUIT CPW19 (VT) AND CIRCUIT CPW20 (WH/OG) FOR AN OPEN 
    • Disconnect: RH Front Window Motor C608
    • Measure the resistance between RH front window control switch C604-3, circuit CPW19 (VT), harness side and RH front window motor C608-1, circuit CPW19 (VT), harness side.
      • Fig 6: Measuring Resistance
      GF0016490Courtesy of FORD MOTOR CO.
    • Measure the resistance between RH front window control switch C604-4, circuit CPW20 (WH/OG), harness side and RH front window motor C608-2, circuit CPW20 (WH/OG), harness side.
      • Fig 7: Measuring Resistance
      GF0016491Courtesy of FORD MOTOR CO.
    • Are both resistances less than 5 ohms? 
    1. YES  : INSTALL a new RH front window motor. REFER to Glass, Frames and Mechanisms - Exploded View, Front Door  and Window Regulator Motor . TEST the system for normal operation.
    2. NO  : REPAIR the circuit(s). TEST the system for normal operation
