I'm thinking its a relay. They front interior dome light does not turn off when its switched to door ajar mode when closing the doors, starting the car, etc. It also doesn't turn off when the car is locked. Also the horn doesn't beep when doors are locked. I think the rear lights go off when the doors close, and hatch alike...just not the front dome. Relay? Thats my first thought, and if so...which one?

ignition switch problems come in multiples usually. On my 90, the door alarms and interior lights are on the same circuit. So since I do not hear the beep from the horn.....I dunno.

switch. IIRC the horn has its own relay.

did you figure out what this was?
