Frequently Asked Questions (FAQs)

1. What are the symptoms of a bad door lock relay?

Some symptoms of a bad door lock relay include doors refusing to lock when pressing the lock button but unlocking when pressing the unlock button, only some doors locking while the car is in motion or parked, and the relay switch losing functionality, resulting in doors not opening or closing properly.

2. Which relay controls door locks?

The door lock relay, responsible for controlling the electric door locks, is typically located near the brake pedal, behind the stereo, behind the passenger airbag, or under the hood of the car.

3. What causes power door locks to stop working?

When the power door locks stop working, it could be due to a problem with the lock actuator or another malfunction within the door mechanism. However, if none of the power locks work, it is worth checking the fuse box in the vehicle as a blown fuse can cause the power locks to stop functioning.

4. What controls the power door locks?

Power door locks are controlled by electric motors that engage and disengage the door locks. Owners can control the door locks using switches or buttons on the door or console, or remotely through a key fob or smartphone app.

5. Can a car run without relays?

Relays are essential for the proper functioning of various components in a car. For example, the starter motor requires considerable current, and without a relay, it may burn out. If the starting relay fails, the vehicle may not start.
