    • 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 SYSTEM WIRING DIAGRAMS article 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

    • 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 
    • 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  in this service information. TEST the system for normal operation.
