Electrical issues.

with the headlights on, all the exterior lights work correctly but both turn signal indicators in the dash will flash and the high beam indicator also will flash. If you hit the dimmer switch, and turn on the left signal the right indicator light on the will flash, and if you put the right signal on. the left indicator will flash, but all the outside light work correctly.

If in these statements you are telling us the exterior lamps work as expected, not flashing on headlight low, and blinking the correct direction when the high beams are on, then the problem is someplace where just the turn and high beam indicator lamps could be seperately effected from the rest.
Probably at the dash itself, slight chance at the column connector.
