I have a 96 Mercury Grand Marquis LS, 125,000 miles. A few days ago I was driving in the rain and decided to turn my headlights on, when I did all my dash lights went off. I couldn't see my speed or nothing else. As long as I don't turn my lights on, the dash lighting works fine. Could you tell me what could be wrong?

Thanks,
Russ Shepherd

when you cut the headlights on, the dash lights will be dimmer then if you didn't have the headlights on. i would make sure that the dimmer switch is not turned down. look there first.

Check the instrument panel dimmer switch and make sure it is not turned all the way down. Dash lighting is normally dimmer with the headlights on than with them off.
