OK arch how would i have fixed it right? There really wasn't anything wrong in the first place.

mythbusters proved it wrong. (the car with windows down ran out first) they had to test it twice since they screwed up the first one (didn't switch vehicles to take that out of the equation) basically if going under 50mph yes a/c will use more gas (about 1/2 mpg) but at speed it won't make a difference

on tv it did, but when they finished (after about 1000 emails and big time bashing on their message board) they finished it, it's supposed to be on a future show, but don't know when. In city traffic stop and go it makes a small difference, cruising steady at 50 or under it uses more (keep in mind you are always spinning the compressor just the clutch is disengaged)

your resistor at the motor is bad, or the switch is bad (you can remove the belt for the a/c and it will still work since it's the inside switch that turns the fans on not the compressor)
