A good place to start would be inside the driver's side door. Check the switches to make sure they are good and all of the adjustments are correct. If that isn't the place then follow the wiring out of the door to the plug under the "T" roof and into the module. If you haven't gotten a Lockzilla I would forget about fixing it till you get one and in the meantime remove the big red wire from the door lock module to the nearby circuit breaker. There is a real possability the door lock module will fail, locking you in the car and burning up the door lock solenoids. Installing a Lockzilla will not fix this problem by itself unless the door lock module is bad causing this trouble.
