ummm, try to recharge your ac and see if it still does it, what it sounds like is your ac pump is drawing too much power, and weakening your circuit flow. it could be a bad pump, check junkyards see if they have any ac pumps for your car, swap it out and see if it still does that. if not, then i honestly dont know. good luck.:smoke:

Replace your A/c pressure switch or regulater. Idk what it's called but honestly don't waste money to recharge it yet because the switch is like 11.50 at autozone. I had the same symptoms as you and recharging didn't do squat besides make it colder but still messed up.
