- Check circuit breaker 3 for continuity.
- Always check terminal contact before replacing any component.
- If express down function does not operate but window operates, check for battery voltage at terminal "A" of express down window module connector. Check DK BLU (164) wire from terminal "C" of express down window module to splice S503 for an open. If both checks are OK, replace express down window module.
- If a motors internal circuit breaker trips, it will not reset until voltage is removed from the motor.
