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

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. 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  E7.
    • No:  GO to E2  .
  2. E2 CHECK THE POWER TO THE WINDOW MOTOR 
    • Ignition OFF.
    • Disconnect: RH Front Window Motor C646.
    • Measure the voltage between RH front window motor C646-1, circuit SBP03 (BU/RD), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes:  GO to E3  .
    • No:  VERIFY Body Control Module (BCM) fuse 3 (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.

      If not OK, REFER to the appropriate SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short. 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 LOGIC POWER TO THE WINDOW MOTOR 
    • Ignition ON.
    • Measure the voltage between RH front window motor C646-3, circuit CBP32 (GN/VT), harness side and ground.

    • Is the voltage greater than 10 volts? 
    • Yes:  GO to E4  .
    • No:  VERIFY Body Control Module (BCM) fuse 32 (15A) is OK. If OK, REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the LH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.

      If not OK, REFER to the appropriate SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short. 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 MOTOR GROUND CIRCUIT 
    • Measure the resistance between RH front window motor C646-4, circuit GD140 (BK/GN), harness side and ground.

    • Is the resistance 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 TO RH FRONT WINDOW MOTOR FEEDS 
    • Disconnect: LH Front Window Control Switch C535A.
    • Measure the resistance between RH front window motor C646-6, circuit CPW12 (GN/OG), harness side and LH front window control switch C535A-2, circuit CPW12 (GN/OG), harness side.

    • Is the resistance less than 5 ohms? 
    • Yes:  GO to E6  .
    • No:  REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the RH front window motor. REFER to WINDOW MOTOR INITIALIZATION . TEST the system for normal operation.
  6. E6 CHECK THE LH FRONT WINDOW CONTROL SWITCH 
    • Carry out the LH front window control switch component test.

      Refer to appropriate SYSTEM WIRING DIAGRAMS article for component testing.

    • Did the LH front window control switch pass the component test? 
  7. E7 CHECK VOLTAGE TO THE RH FRONT WINDOW CONTROL SWITCH 
    • Disconnect: RH Front Window Control Switch C648.
    • Ignition ON.
    • Measure the voltage between RH front window control switch C648-2, circuit CBP32 (GN/VT), harness side and ground.
