Role of Fuses and Relays:

Fuses: Protect the door lock circuits from electrical overloads. A blown fuse will prevent the locks from working.
Relays: Act as switches that control the power to the door lock actuators. A faulty relay can prevent the actuators from receiving power, leading to a failure in operation.

Have you had to replace any fuses o r relays related to your power door lock system?
