Audi 90 Dome Lights Problem

[Derick Farfan <bg18461@binghamton.edu>]

In my 88' 90 the interior lights do not come on when I open any door, or
when i turn the key to unlock the doors.  Then when I move the switch to
the open door icon on the lights the lights stay on no matter if the
door is open or closed.  While the lights are switched in this position
while i am driving it might intermediately go off. Also, when i turn the
key to start the car the lights stay on.  I have switched the blue relay
under the dash with a known working one (my dads 87 5000), and i know
how its supposed to work, but it is not.  Can anyone help me figure
where else to turn.  Maybe checking the door pins, which one to start
with?  TIA
