![]() ![]() Sometimes it's just a simple matter with that being the problem. One thing that's worth testing if you find yourself outside the car and you can't unlock it with your key fob is to ensure that the battery in your key fob has actually been replaced. You'll know this is an actuator problem rather than something else if the electrical systems in your car still work and you're still able to unlock the door with a key. The most obvious sign that there's a problem with your door actuator is that the locks just don't work at all. However, depending on how the actuator is failing it's possible that when you press a button to lock or unlock your door it will begin to work but it will struggle so much that it actually takes a moment for the locking mechanism to engage. A simple click in the door is unlocked or locked and you can go about your business. if the noise gets continually louder, then you're likely closer to the problem getting worse and the actuator failing completely.Ī power door lock should work almost instantly when you press the button. These won't be as loud as something like your transmission failing, but they will definitely be some kind of whirring or grinding noise that you are not used to. You'll notice sounds from inside your door that are not typical to the way your car usually operates. When those moving Parts begin to fail it works not unlike any other moving Parts in your vehicle when they begin to fail. That can cause the door to unlock immediately after locking.Īs we've said, the door actuator includes a motor, gears, a linkage, and a Rob that will raise and lower to lock and unlock your door. If the bumper has failed, then the mechanism won't be giving the signal that the lock is actually finished doing its job. ![]() When your lock is working normally there is a current spike when the lever hits his bumper at the bottom. It's also possible that the bumper stop that prevents the lever from hitting as the lock raises and lowers has broken. This problem can be caused by not just an actuator issue but a frayed wiring harness in the door hinge. Additionally if there are wiring or electrical issues then you might find that your door will have problems in which it seems to lock and unlock on its own or several times in a row even though you haven't pressed any buttons to make it do so. That means it will be working sometimes but not other times. If you start experiencing any of these problems, you should get your car to a mechanic whenever it's convenient for you so that you can prevent the issue from going from bad to worse.īecause your door actuator is an electronic component, as it begins to fail it will typically perform in a very spotty manner. There are a number of signs you can be on the lookout for that will let you know there's a problem with the actuator in your door before it gets so bad that you simply can't unlock it anymore. How Do I Know if My Door Lock Actuator is Bad? If all the doors fail at the same time, then that is very likely caused by a defective switch or some kind or a blown fuse. Mechanical issues will be isolated to the single door in which the mechanical problem has occurred. The mechanical linkages can wear out or latch assembly can prevent the motor from moving which causes the mechanism to stall. This can be a result of your battery being dead, or a fuse blowing as well. If your actuator isn't getting the proper electrical signal any longer it won't be able to function. The most common cause for this to fail in your car is because it wears out from simple wear and tear over a long period of time because there are a lot of moving parts in here including gears and the retractable cable and it can also be an electrical issue. Usually when a door actuator in a car fails it happens on the driver side because that's obviously the door that's going to get you as more often than the others. A clutch will disengage from the gear so that you can lock or unlock the door manually inside the car or with the key for outside it if you choose to do that as well.īecause you can still manually use a key to lock and unlock a door when your door actuator fails it isn't necessarily any emergency problem that needs to be addressed right away, but it will definitely be annoying if it doesn't work properly any longer. When you press the button on your key fob, on the door itself, or punch in the electronic code depending on the kind of lock you have it sends a signal to the actuator telling you to either open or close the lock as necessary. The motor in your actuator gets power from the battery so it can't work if you have no battery power left in your vehicle. A door actuator is an electronic mechanism that raises and lowers a rod that connects to your door lock.
