Pinpoint Test A: All Passenger Power Windows Are Inoperative - MKZ, LH And RH Rear

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.
NOTE: Before performing this pinpoint test, make sure the master window lockout control switch is in the UNLOCK position.
  1. A1 CHECK FOR VOLTAGE TO MASTER WINDOW CONTROL SWITCH 
    • Disconnect: Master Window Control Switch C535B.
    • Ignition ON.
    • Measure the voltage between master window control switch C535B-3, circuit CBP47 (GN/BU), harness side and ground.

    • Is the voltage greater than 10 volts? 
      • Yes:  GO to A2.
      • No:  VERIFY SJB circuit breaker 47 (30A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.

        If not OK, REFER to the Wiring Diagrams manual to identify the possible causes of the circuit short. TEST the system for normal operation.

  2. A2 CHECK THE MASTER WINDOW CONTROL SWITCH GROUND CIRCUIT 
    • Ignition OFF.
    • Measure the resistance between master window control switch C535B-6, circuit GD126 (BK/WH), harness side and ground.

    • Is the resistance less than 5 ohms? 
      • Yes:  GO to A3.
      • No:  REPAIR the circuit. TEST the system for normal operation.
  3. A3 CHECK THE MASTER WINDOW CONTROL SWITCH 
    • Carry out the master window control switch component test. Refer to COMPONENT TESTING for component testing.
    • Did the master window control switch pass the component test? 
      • Yes:  REPAIR circuit CPW14 (VT/WH) for an open. TEST the system for normal operation.
      • No:  INSTALL a new master window control switch. REFER to Window Control Switch  . TEST the system for normal operation.
