  1. Turn ignition on. Check voltage at the following wire terminals of main switch connector. If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, replace main switch.
    • Green/White wire (main switch/passenger's in UP position)
    • Red/White wire (main switch/passenger's in DOWN position)
  2. Check voltage at the following wire terminals of sub-switch connector. If battery voltage is present at all terminals, go to next step. If battery voltage is not present at all terminals, repair wiring between main switch and sub-switch.
    • Green/White wire (main switch/passenger's in UP position)
    • Green/Yellow wire (main switch/passenger's in DOWN position)
  3. At sub-switch connector, check voltage at Red wire terminal (main switch in UP position) and Green wire terminal (main switch in DOWN position). If battery voltage is present at both terminals, go to next step. If battery voltage is not present at both terminals, replace sub-switch.
  4. At window motor connector terminals, check voltage at Red wire terminal (main switch in UP position) and Green wire terminal (main switch in DOWN position). If battery voltage is present at all terminals, replace window motor. If battery voltage is not present at all terminals, repair wiring between sub-switch and window motor.
