What to know about the Door Lock Switch:
Door lock controls are electrical rocker switches that are used to lock and unlock car doors. When you activate the switch, it sends information to the door lock relay to activate the door lock actuator inside the door. Due to frequent use, the switches and electrical currents running through them eventually fail, demanding replacement.
Facts to Note:
Many modern vehicles have a full set of lock assembly which needs to be changed if the switch fails.
How to fix:
Test the working of the electric door locks.
Test the fuse for that circuit.
Test the relay.
Change the faulty door lock switch.
Test for proper functioning of electric door locks.
Door lock systems are not a part of regular maintenance, but it’s common for the switches to die. If you observe that your vehicle is not locking and unlocking when you press the corresponding buttons, it’s time to schedule a checkup.
Common symptoms indicating you may need to replace the Door Lock Switch:
Doors will not lock or unlock with the switch.
Importance of this service:
The door lock switch functions as a remote for the door lock actuator, which takes charge for locking and unlocking your vehicle’s doors. When you press the lock or unlock button, the switch triggers the actuator, and the door is locked or unlocked. When the lock switch fails, the actuator has no way of being activated, and your door locks will stop working.
