Saturn 84243380 Actuator

The power door lock system operates using door lock actuators mounted in each door and includes switches, actuators, lock and unlock relays, the Body Control Module (BCM), and associated wiring. Diagnosis usually involves simple checks of wiring connections and actuators for minor faults. The system utilizes bi-directional solenoids in the doors, mounted as part of the door latch. Lock switches have Lock and Unlock positions, sending signals to the BCM, which activates the door lock relays, providing voltage to each door lock solenoid. To troubleshoot, check circuit protection first, including fuses and circuit breakers. Verify voltage at the switches and check for continuity; if necessary, replace faulty switches. Check the wiring between the switches, BCM, door lock relay, and solenoid if needed. In case of an inoperative solenoid, test for voltage and ground, check for breaks in the wiring, and replace the solenoid if necessary. Communication for the power door lock system passes through the Body Control Module, and if the issue remains unresolved, retrieve trouble codes from the BCM using a scan tool. The keyless entry system uses a remote control transmitter sending an infrared signal to the receiver to operate the door lock system. Replace the battery when the transmitter's range decreases. To replace the key remote control battery, carefully separate the case halves, replace the battery, and snap the case back together. Programming replacement transmitters requires a specialized scan tool, so take the vehicle and transmitters to a dealer or qualified repair shop with the necessary tool to have the transmitter(s) programmed into the vehicle. Up to eight key fobs can be programmed to one car, and all fobs must be present during reprogramming.
