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

  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 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 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
