While driving home last night, and while out over lunch today, the A/C started to blow warm air. While this was happening, I noticed that the outside air temp light was blinking. I turned the A/C off and back on, and the A/C started working again. Anyboby HTH, and what might the problem be. Low refrigerant, sensor? TIA Marty Herrick Milwaukee, WI '90 V8Q
