Hi, How are you? My name is XXXXX XXXXX I will try to help you with this problem.
I am sending you diagram. according to wiring you can grond ajar switches one by one untill you find the faulty one.

Thank you for the diagram. Where are these wires located?
Are the switches in each door?
yes, they are part of the door latch.you can follow the wire colors. but instead open every door you go to VCM and you can ground the wire right there.
Here are the wire coding
Thanks again. Just to be clear, can you explain what you mean by grounding. Do you mean remove the wire from the VCM and attach it to a bare metal location with another wire?
Also, is the VCM under the dash?
No, if you look at the diagram, wire is opened by the switch. Goes from VCM to grond. when switch is open then door is open. and light is on. you need to connect VCM wire to car metal part. If youare not sure what you are doing print this and ask someone for help otherwise you can damage that module if you go to wrong wire. You can always comback and talk to me if you need me.
Understood. Where is the VCM located?
underdash/ and here is door ajar switch
Would a test-light work in determining which switch is bad?
Sorry, module is located behind rear seat R/H side in the right panel. test light yes but you have to connect it to power at clip side.
