Car Door Lock Actuator Wiring

I try to provide tips to help you install on your vehicle.

Car door lock actuator wiring.

How a door lock actuator works. On manual locks the locking function operates by pushing or pulling on the door lock. Another symptom of a potential problem with the power door lock actuators are door locks that behave erratically. To the coil of the respective relay.

Power door locks do not function. The items we have are a cfd universal car power door lock actuator 12 volt motor a docooler car remote central lock locking keyless entry system with remote controllers. A door lock actuator is basically a reversible motor or a solenoid on some vehicles with gears that operate the door lock. When the actuator fails or starts to fail you ll likely notice one or more symptoms that make your daily commute less pleasant.

On a vehicle with electric locks the process is a bit different. This manipulates a series of rods that slide back and forth opening and closing the locking mechanism at the door latch. The remote has 10 wires coming from its harness. Both motor legs rest at ground at the relays.

If there are no external door lock switches you will most likely have a vacuum type system or an aftermarket door lock system with relays or have an added actuator that needs relays. Next with your multi meter probe each of the wires in this harness and write down the readings during lock unlock and at rest positions of the switch.

The concept of a door lock actuator works great until it doesn t. If the actuators have any sort of internal or wiring issue it may cause them to rapidly lock and unlock unexpectedly or cause them to function intermittently. To lock or unlock the vehicle polarity is changed on one motor leg via a positive pulse from a switch alarm keyless entry etc. In some cars the door lock actuator is positioned below the latch.
