Power door lock problems can be frustrating. If your power door locks are not working, you may be tempted to take the car in for service. However, it’s worth trying to diagnose the problem yourself first. This can help you avoid unnecessary expenses and save you from having to deal with an overbooked mechanic who does not have enough time to work on your vehicle. In this article we will discuss how to troubleshoot power door lock problems and how to fix them yourself – no tools required!


The first step in diagnosing a door lock problem is to check the door lock mechanism. It may be that the latch has become loose or that there is a problem with the striker (the part of your car’s body that holds onto the latch). Try pushing down on the handle and see if you can get it to move more than an inch or two. If not, then this would be an indicator that something is wrong with your door latch.

Next, check for any issues with relays and wiring by checking them for resistance. A bad relay will have high resistance when tested and should be replaced if it fails this test. You can also use a multimeter to test all three pins on each relay to ensure they are functioning properly before moving onto other steps in diagnosis.

The driver’s side door switch could potentially be bad as well; remove the panel covering it up and inspect both sides using an ohmmeter (a tool used to measure electrical resistance). If both sides of this switch read open circuit then you know this component needs replacing immediately!
