To start troubleshooting, if you have not already done the following.
Pull both the door switch wires off the switches.
The lights should go out. Ground both the wires to the frame at the same time and the lights should come on.
(The switches "ground" or complete the circuit, when the doors open, and the circuit is "open" when the doors are closed and the switch is "pressed")
If the lights stay on, then the switches are not the problem.
