Dash lights causing turn signal woes

[Rick Bollinger]

Well I put the lights on the back burner while I got the factory a/c working. Tonight I cleaned the grounds and the sockets with no success. I even went so far as to run a long ground wire to each of the lights directly from the battery and wedge the bare wire between the bulb and socket with no difference. I cleaned the two plug in's going to the steering column. I did notice when I would remove the front driver side parking / turn signal bulb or un plug it my dash lights would go out. Even my high beam indicator light comes on when I turn on the parking lights. But when I turn on the light it will shut off on low beams. All the fuse's are hot in the fuse box. Any other thoughts?
