Component Tests and General Diagnostics

1. Check the PWR ACC Circuit Breaker.
2. Check the CTSY, INDIC and Stop Fuses by visual inspection.
3. Check Power Window Circuit Breaker.
4. Check for mechanical binds in the Door Lock System.
5. If one of the Door Lock Motors does not operate properly, but the other Door Lock Motors function normally, check the wiring to the suspect motor. If the wiring is correct, check for a poor connection. If OK, replace the motor.
6. Check that ground G305 is glean and tight.

[!] Important:

^ For diagnosis of Power Door Locks on vehicles equipped with Keyless Entry, see "Keyless Entry".

7. Check that the Dome Light Switch is in the "OFF" position.

^ Check for a broken (or partially broken) wire inside of the insulation which could cause system failure but prove "GOOD" in a continuity/voltage check.
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems.
