[s-cars] Lights Out

[David Giannandrea]

I have a 93 S4 and the enunciator for a burned bulb keeps enunciating. It is
intermittent and I can't relate any situation to what is triggering it. I've
changed/checked all the bulbs I think are related to the indicator: in front
we have hi,low, turn, running, fog, in the rear we have brake, running,
turn, fog (1). Everything is working. I even changed all the little bulbs in
the 3rd brake lite on the rear shelf.

There is a double relay in the relay panel in front of the driver. I pulled
it and then got double enunciations, solidly lit: 'Brake Light' and the
x-bulb.

I've heard that the check system does resistance comparisons to determine
failure. It does not need to have the bulb lit to do the checking...as the
indicator will announce at any time, day or nite, cruising with no
brake-lites lit.

Anybody have any ideas on what to do next??
