Door Lock Actuator
Having faulty door locks in your vehicle is always bad news.not only will your ride become a thief magnet, but it will also become unsafe to drive. Aside from not being able to leave stuff inside your car, there's also a big chance that you might get locked in or locked out of your ride. This will prove extremely inconvenient, especially if you're in a hurry. Oftentimes, a busted lock is caused by a malfunctioning door lock actuator. This component is pretty simple and it's basically made up of a small electric motor and some gears. The motor turns some spur gears, which serve as a gear reduction. And after that, the rack-and-pinion gear set is activated and converts the motor's rotational motion into linear motion, which then moves the lock. If the motor or one of the gears in the actuator fails, the whole system is compromised, making you and your vehicle vulnerable. Here's a short guide that will help you troubleshoot and repair the damage of your busted door locks.
Symptoms of a Broken Door Lock Actuator
- Erratic operation
- Malfunctioning car alarms
If your door locks are always a hit or miss, you might want to check the actuator to see if it's the source of the problem.
A busted lock actuator in your car doors can also affect the alarms that you have installed.
If you hear odd sounds coming from the door locks every time you operate them, check the actuator right away.
Replacing a Broken Door Lock Actuator
Door lock actuators can get damaged after years of continued use. One probable cause is having constant exposure to moisture, which then yields to the formation of rust. Here's a quick how-to that you can follow for your door lock actuator repairs. Note that some of the steps below may vary depending on your vehicle make and model.
Step 1: To begin, remove the inner door trim of your vehicle, starting from the window side edge in the upper part of the door trim. Do this easily by grasping it with your hand and pulling it out.
Step 2: Next, remove the armrest switch panel by carefully prying it out, starting from its narrowest end. Once it's out, remove the screw that's behind it.
Step 3: After that, locate the connector lock tab and press it in before pulling the connectors of the switches off. Then, remove the switch panel completely out of the door.
Step 4: Next, slide the door trim panel to remove it, making sure that you don't damage it in the process. When the panel is out, remove the insulating sheet behind it as well.
Step 5: After that, remove the rods of the door latch to get the latch assembly out. When it's removed, disconnect the electrical connector from the actuator while holding the latch and prying out the spring tab.
Step 6: When the spring tab is raised, slide the old door lock actuator out and install the new one.
Step 7: Plug the connector to new actuator and reinstall all the other components that you removed earlier.
