Turn on one light and leave it on for a little while then turn it off. Turn the next light on and open the door. Go up and feel the light bulbs..the warm one is the first loth switch,, the one that is still on is obviously the second light switch and the cold/regular temperature light bulb is the last switch that you didn't touch.

Why will the 1990 corvette interior lights stay on at times and kill the battery door switches check ok?
In cases like this it is best to use an anolog meter instead of a digital meter,I say one of your switches is bad, rarely is it both switches,if the wiring has not been tampered with, the switch is breaking the contact to the light when the door is closed,when the door or doors are opened current or volts flows. sometimes a digital meter is to fast to detect the fault, current is leaking by one of the switches. disconnect the battery, or remove the bulbs until the problem is solved.
