5. Defrost the lock

To check an individual lock mechanism, work the door lock manually up and down (or backwards and forwards in newer vehicles) while using the auto lock button at the same time. Just make sure the key is “on”.

  • If the lock “tries” to move, then the problem could be a frozen lock mechanism or a faulty solenoid.

For a frozen lock, you can use a hair dryer (or the flame from a match or lighter) to heat the key or the lock mechanism itself, to thaw it out.

  • Another option is to use a lock de-icer or even a battery-powered key that heats up and melts the ice.

Testing the motor

The other possible issue is a dead motor. At this point that is the only thing left to check. You can check it in the same way as the actuator. Connect some wires to a 9-volt battery and then connect the probes to the motor.

A working motor should make sounds and try to spin. If it doesn’t, then it is dead and needs to be replaced. Again, just buy or order a replacement part and install it.

If the motor isn’t bad and none of the other things are bad, then you have or had a problem with how the lock was put together. Reassemble the lock, and it might work again. The problem might have been a bad connection that you just didn’t notice.

How Do I Fix a Broken Actuator?

You may find that the other doors on your car are

You may find that the other doors on your car are working fine but your driver’s door won’t budge. Have some relief knowing that this hasn’t happened because you have done something.

The driver’s side is prone to breaking before the others because this door is the one that gets used every day. This is why we are going to concentrate on explaining how to fix a broken actuator in the driver-side door.

1. First, remove the door panel and carpet

To remove the door plastics and carpet you need to locate all the screws and loosen them. You can use a flat head screwdriver or something similar to pry off the lock mechanism and power buttons but be careful as these can be extremely fragile. Once all the screws are out the door panel will pop off.

2. Inspect

Now you have a full view of the inside of your door, don’t be alarmed to see a lot of wiring and clips in place. In fact, you should now check that there are no loose connections. If the connections look good then it is time for you to test the actuator.

If you can manually lock your door then try it. If you hear a clicking sound coming from the door then it means that power levels are good but the actuator is at fault. 

3. Removal

Removal of the old actuator is fairly simple. Taking the clips out of the old actuator can be fiddly and I always advise you to take photos before you start disconnecting wires. This will help you understand where they go in the new one. 

The clips are extremely fragile and can be stubborn to release from the actuator so it is important to be gentle or you will snap them and need to replace them as well. 

The next step would be to unbolt the window strap and then unbolt the actuator. (It is always handy to have some basic tools to hand to make this job easier.)

Once you have loosened the actuator you can disconnect the connectors for both. You are now able to remove the actuator but be warned. It may be fairly comfortable so you may need a little force to pull it free.

4. Install the new actuator

Now you have removed the old one it’s just a matter of reinstating the new one in its place. Ensure that you bolt the actuator in and reconnect the wiring.

This is where those pictures you took come in handy! You may wish to test the new actuator out at this point to ensure that it is all connected properly and then it is time to put the door panel back on and clip it back securely.

What is the Cost to Fix Power Door Locks?

It goes without saying that the money you would need to have your door lock or locks replaced would depend on the cause. It will also depend on the parts that you need to purchase. Keep in mind that parts also come with different brands and quality, affecting their cost.

Whether you would hire a professional or not to diagnose and fix the issue will also affect the total cost of fixing an auto door lock not working issue. Lastly, your car’s brand and make will have an effect on the money you need to spend to get the lock fixed.

With that said, you should expect to spend an amount ranging from $50 to $200. If done professionally, you might spend between $200 and $700.

2. Replace the key fob

If that doesn't solve the problem, you may have a faulty key fob.

  • Go to a dealer and they will be able to hook up to the computer that controls your keyless entry and make sure the key fob is still programmed.
  • If the key fob isn’t sending a signal, it will need to be replaced.

Conclusion

So, now you know why only your driver side door isn’t working. You know that locks are made up of gearboxes, motors, and actuators and any one of these parts can break at any time within a single door.

Now you know what to look for though if you only have one lock that isn’t working. You know to start with lubricating the lock and see if that fixes it before taking it apart.

If you have to take it apart though you now know to look for broken gears in the gearbox and how to test the motor and actuator to see which one might be bad. You then know how to replace it, so the next time your driver side lock isn’t working, or one of your other locks isn’t working you will be able to troubleshoot it and fix it yourself.
