Lighting problem

1998 Intrigue...When the parking or headlights come on, the insturment
panel lights go off (radio, odometer, hvac controls). This occurs whether
the auto system turns the lights on or the manual switch. The panel lights
work when the lights auto off or are manually turned off. I would
appreciate any tips of where to look. BTW, all bulbs are working properly,
along with the DRL's. Thanks.

It sounds like the panel lights are not properly grounded and
are grounding themselves through the headlamp circuit when the hdlmps
are not on. When the hdlmps are on, the panel lights are no longer
grounded and then don't work.

There were no repairs or modificaations done when the problem occurred. If
this is the case, where should the panel lights ground? And how could they
ground to the headlamps when they are on a different circuit? (Just trying
to make some sense of it).

Thanks for your reply.

Unfortunately, I do not know the answers to those very important
questions. A schematic would help...
