Symptom No. 3

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