Know about Power Door Lock Actuators
The behind-the-scenes mechanism that locks and unlocks your vehicle’s doors with the push of a button is the power door-lock actuator. Mounted inside the door, it includes an electric motor, gears and linkage, or a cable that extends or retracts to operate the lock. On many modern vehicles, the lock actuators are monitored by electronic controls (such as the body control module) that have to receive the correct antitheft code from a key fob transmitter before they’ll send electrical current to unlock the doors. Each door has its own power lock actuator, and the motor turns in one direction to lock the doors and the other to unlock them. The linkage typically has a hook on the end that moves the lock up or down, making it similar to having a permanently installed “Slim Jim.”
Actuators can stop working or develop intermittent problems because dirt gums up the gears or the motor fails from long-term use. This is the most common reason that the actuators stop working.
It also could because of electrical contacts or circuits wear out.
1. Make sure the wire connector has power.
2. Lubricate the lock latch, lock rods or cables. make sure the lock rods/cables are connected properly.
The lock rods/cables may become not as smooth as original after the position was changed during replacing the actuator.
Lubricating the lock rods/cables by spray some WD40 on them is strongly recommended.
How to Replace Door Lock Actuators
Important Tips: There are several steps and quite a few parts involved in this project. It might be a good ideal to take your phone or camera and take pictures during each step of disassembly, so you can be sure everything comes back together again properly during the repair/replacement phase. Remember that taking things apart is always a lot easier than putting them back together again!
