    • Is the voltage greater than 10 volts? 
    • Yes  : GO to E4.
    • No  : REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the LH rear window motor. REFER to WINDOW MOTOR INITIALIZATION  in this service information. TEST the system for normal operation.
  4. E4 CHECK THE LH REAR WINDOW MOTOR GROUND 
    • Ignition OFF.
    • Measure the resistance between LH rear window motor C703-2, circuit GD133 (BK), harness side and ground.

    • Is the resistance less than 5 ohms? 
    • Yes  : GO to E5.
    • No  : REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the LH rear window motor. REFER to WINDOW MOTOR INITIALIZATION  in this service information. TEST the system for normal operation.
  5. E5 CHECK CIRCUIT CPW15 (YE) FOR AN OPEN 
    • Disconnect: LH Front Window Control Switch C504.
    • Measure the resistance between LH rear window motor C703-5, circuit CPW15 (YE), harness side and LH front window control switch C504-14, circuit CPW15 (YE), harness side.

    • Yes  : GO to E7.
    • No  : REPAIR the circuit. DE-INITIALIZE, then INITIALIZE the LH rear window motor. REFER to WINDOW MOTOR INITIALIZATION  in this service information. TEST the system for normal operation.
  7. E7 CHECK THE LH FRONT WINDOW CONTROL SWITCH 
    • Carry out the LH front window control switch component test. Refer to COMPONENT TESTING article, for component testing.
    • Did the LH front window control switch pass the component test? 
  8. E8 CHECK THE POWER TO THE LH REAR WINDOW CONTROL SWITCH 
    NOTE: Make sure the LH window control switch is in the UNLOCK position.
    • Ignition OFF.
    • Disconnect: LH Rear Window Control Switch C701.
