I finally broke down and took the car to the dealership. I was informed that the freon was low and that the only way the positively detect a leak was to place dye in the system (for a $175 fee) and allow it the opportunity to work its way through. I was told to bring the car back when I experience the problem again. The system is cooling very good now, however I noticed when looking in the class window on the canister that it boubles whenever the aux fan kicks in. I was curious if this indicated anything or not. Any insight would be appreciated.
