- A1 CHECK REAR PASSENGER WINDOW VOLTAGE FEED TO LH FRONT WINDOW CONTROL SWITCH
- Disconnect: LH Front Window Control Switch C535B.
- Ignition ON.
- Measure the voltage between LH front 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 appropriate SYSTEM WIRING DIAGRAMS article to identify the possible causes of the circuit short. TEST the system for normal operation.
- A2 CHECK THE LH FRONT WINDOW CONTROL SWITCH GROUND
- Ignition OFF.
- Measure the resistance between LH front 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.
- A3 CHECK THE LH FRONT WINDOW CONTROL SWITCH
- Carry out the LH front window control switch component test. Refer to COMPONENT TESTING - EXCEPT HYBRID and COMPONENT TESTING - HYBRID .
- Did the LH front 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 LH front window control switch. REFER to Removal and Installation . TEST the system for normal operation.
