My "Door Ajar" light won't go off in my 04 Impala. Any ideas? I've checked everything, even unplugged the battery, etc.This also keeps the interior light on. The car thinks there is a door open, but there is definitely not.
I sprayed WD40 in the handle opening and moved it up and down a few times and sprayed some in the latch and it went away.
One of the door switches went bad. Start with the door that is most used, pull the switch out unplug it and test it for continuity with the button pushed in, if there is continuity with button pushed that is your bad switch. This can be a pain cause cause you will have to remove the interior panels to gain access to the switches plugs from inside the body panels. If you test all switches this way and they test good. than it is the BCM or body control module. Or whatever name GM gives it.
