Take a look for a lighting relay or fuse especially if it doesn’t matter which door is not triggering the lights. Most likely the wiring from each door switch comes together at a relay and the relay contacts are what enable the lights to come on. Sorry I don’t have details on the specific model but you might be able to locate one or two fuse/relay boxes (normally one under hood and possibly one below the steering console around the gas or brake pedal area. Good luck!
