My door locks are malfunctioning and causing my battery to drain. I removed the Door Lock Relays from the interior fuse box, and recharged my battery. The battery did not drain, so I know the relays are not the problem. The next step that I was told to do, is to check the interior door lock switches.
How do I know if the interior door lock switches are bad? on 2001 Saturn SC2
Yes, since you localized the battery drain to the door lock circuits, then the next thing to do is to get a test light and connect it between the door lock fuse connection points and then disconnect each door lock switch individually. I would start with the drivers door, because it gets the most wear and tear. You may have to remove the door panel in order to check the switch, but possibly you can get to it if you remove the door lock from the door, at least enough to unplug it.
Thank you so much for the information you are giving me, but please forgive my ignorance - in following your directions about the use of a "Test Light", are you referring to a "6 and 12 Volt Circuit Tester"? And, I do not know where the "door lock fuse connection points" are. By your directions, I'm guessing that I will find the connection points when I remove the door lock switch. With the Test Light, if the light comes on, does that mean the door lock switch is good? And if the door lock switches are good, would I then go to the "Door Lock Actuator" to continue in looking where the problem is? (I learned how to do almost any repair on my '72 Olds Cutlass, but this newer car, with all the power accessories, has me baffled. I'm trying to complete this repair on my own.)
