I have a 95 ponitac bonneville, when I pull the switch to turn it on, the headlights only go on. My dash and tail lights will not go on. When I press the brake my dashboard lights go on. When I release the brake the ddash goes back off. Help anyone

Sounds like a bad ground.
Try your 4 way flashers, walk around the car and tell which work.

Its not the ground bus, already checked that, checked the fuses all work, my emergency lights all work, are there other ground wires

Hopefully Captainrich or TxGreasemonkey will provide additional info or a schematic for your car.
Any recent wiring, Stereo, accessories?

Does the dimming work on headlight switch, leaning towards headlight switch.
