When I turn on the headlights or heater/ac the turn signal indicator lights and high beem indicator light comes on. But the heater/ac does not work and when this happens my turn signals and hazard lights don't work. I've been to the dealer and they have never heard of this but will say it's an electrical problem. Any ideas?

My guess is there is a ground issue happening. When this happens, if the ground is bad, power will back feed it's way through a different circuit. In this case, it is going through the signal/high beam circuit and causing the lights to come on. Check body grounds to confirm they are all good.
