Tips On How To Troubleshoot Power Door Locks


A remote keyless system is very amazing. Someone can get away from the car without locking the doors about twenty to thirty feet away, remember and hit a button and the power locks to engage and lock all the doors. There's no need to check to make sure they are all locked. Actually, that's pretty awesome.

Nowadays you can open or close doors or hatches on vehicles. One of the things that appeals to me is that you can unlock just the driver's door or all of them. That is important to me. When I am out late working or shopping, as I approach my car, I try to be aware of the people around me. Sometimes, someone might make me nervous; there might be something about them that is not quite right. You understand what I mean? It is then that I appreciate the fact that I can unlock just the driver's side - my door and gain access to the car quickly and securely. With the touch of a button inside the car, the power locks make sure that all doors are locked and secure.

Power locks gives a mother control over the vehicle's doors with small children on board. Nothing could be more frighteningly than to have a door opened by a stranger with little ones in the back seat.

Without a doubt, power locks can also keep the accidental door opening from happening. By being able to lock and keep them locked, the doors are under control by the driver.

If your vehicle is an older model without power door locks, do not despair. You can either install them yourself or have them installed. The power door locks can be added to two doors or all doors of your vehicle - your choice.

Troubleshoot Power Door Locks

Although, power door locks are very effective in their working, they usually develop many problems. The cool thing is that you can easily troubleshoot the problems and correct them.

Car Power Door Locks Won't Work

If the relay is receiving the right voltage, but the voltage isn't coming out you should replace the relay. If the voltage is coming out of the relay, chances are that the motor has corroded internally and you need to clean it. If you have the skills you should dismantle the motor and clean it. If you don't have the skills you should ask a professional to help you with the cleaning.

If one or two doors have stopped working, the problem must be within the doors. What you need to do is to remove the door panels and check if the motors have 12 volts. You should note that you need to confirm this while holding the driver's door button at the lock position. You should also check the voltage in the unlocked position to prevent a situation where car power door locks won't work.

If you get 12 volts in both the lock and unlock positions you should take a look at the motors. If you don't get 12 volts in the motors chances are that the one or both of the wires are broken in the door hinge area.

You need to pull the wire harness further into the door in order to inspect the breaks. Please note that you might be required to disconnect the rubber boot from the door in order to access the wires. You should repair any breaks using a solder or crimp connector.

Tips To Consider

To make your work easier it's wise that you have the electric door locks wiring diagram with you. This will make it easy for you to locate and identify wires and other areas that might be having a problem.

If you are wondering where you can get the diagram you should take a look at your motor vehicle service manual. If you don't have the manual you can buy one at stores that sell automotive parts.
