Symptom No. 2
- Turn ignition on. At main switch connector, check voltage at Green/Blue wire terminal (driver's switch in UP position), and Red/Blue wire terminal (driver's 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 main switch.
- At driver's window motor connector, check voltage at Green/Blue wire terminal (driver's switch in UP position), and Red/Blue wire terminal (driver's switch 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 main switch and window motor.
