How door lock actuator works.

But first let s see how the car keeps all its signals straight. Attach the plastic door lock actuator back onto the. Reinstall the plastic cover and replace the assembly. In many cars the door lock actuator is built with the latch mechanism into one assembly in the photo.

The door lock actuator is an electric actuator that operates the door latch mechanism in cars with power door locks. The power door lock actuator is a pretty straightforward device. A small electric motor turns a series of spur gears that serve as a gear reduction. Then when you press the switch to lock the doors the lock moves in the opposite direction.

Door lock actuators are an electronic component found on vehicles equipped with power door locks. Spray electrical cleaner onto the black electrical connector. To lock or unlock the vehicle polarity is changed on one motor leg via a positive pulse from a switch alarm keyless entry etc. Inside the power door lock actuator.

The motor reverses direction so that when you press the switch to unlock the doors the lock moves in one direction. Part 5 of 6. This system is quite simple. How a door lock actuator works on manual locks the locking function operates by pushing or pulling on the door lock.
