Can you tell me what your exact issue is with the interior lights?
The foot well lights actually share the same power source from the body processor module but have different grounds. We should make sure fuse #5 and #7 both 15 amp in the driver side dash fuse boxes are good. Next go right to the driver footwell light connector and see if we have power to the brown/white wire. If we do then see what it reads on the other wire as if we have power to both sides we are missing the ground. Let me know.
Ok if there is no power there and the passenger side works then there is a wiring problem like a bad splice joint. Take a jumper wire from the brown/white on the passenger side to the brown/white on the driver side and see if the light works.
