To fix a power lock actuator, take out the relevant door panel and the weather shield, and then unlock and lock the door while moving the rod that goes to the actuator a few times. Apply lubricant over the rod and actuator, and apply oil on the actuator's end. Unlock and lock the door several times, and refit the weather shield and the door panel.Continue Reading
Begin fixing a power lock actuator by taking out the door panel with the malfunctioning lock using Philips and Torx screwdrivers. Refer to the schematic of the vehicle to locate the screw positions. Then, slowly detach the weather shield that covers the internal parts of the door, and keep it safely aside.
Hold the rod that goes to the actuator and connects to the lock by hand. Unlock and lock the door a few times using the fob or the switch on the door, and shift the rod while doing this.
Finish the lock-unlock cycle by leaving the rod in the unlocked position, and apply silicone lubricant generously over the actuator and the rod using a sprayer. Leave the lubricant on for around 10 to 15 minutes for proper penetration.
Next, place two to three drops of household oil using the tip of an oil applicator. Allow the oil to penetrate for a few minutes.
Again unlock and lock the door several times to distribute the lubricant and oil uniformly. If the actuator and the lock operate as required, reassemble the weather shield and the door panel.Learn more about Car Parts & Maintenance
