Theres one screw holding the light switch at the middle of the driver
door frame in the front. Its got the plunger that switches the light
on when its out. If you unscrew it and pull the switch and its two
wires out you can touch them together to see it will turn the lights
on. If its not there, it might be in the light switch itself which
pops out fairly easily. Try bavauto.com if you need a new switch. When
reconnecting the door switch connect the wires back to the switch and
careful not to let them fall into the hole. I dont know if theres any
dome light relay in that car, i am fairly sure there is not. I also
think it wise to first try with a multimeter at the door and driver
override switches. If you do not have one or are unable to use one (or
a test light), then just order the driver override switch to the left
of the steering column on left hand drive cars. Its very probably
that. Im tired and burnt out, i dunno if my answer has been rambling
and nonsensical...if it has consult the rosetta stone and perhaps have
the dalai lama read the tea leaves. Therein your answers lie.
Muhahahahaha. Muhahahahahahahahahahaha. Ahem
