Has anyone experienced a situation where you are driving with the AC on and it changes from cold air to hot heater type air and then back to cold in a span of about 3 to 5 minutes. Can someone shed some light on what might be the problem????

you need to hook it up to some gauges and watch what the pressures are doing and watch to see if the compressor drops off. if you dont have gauges take it to a ac shop.trying to doctor it up can cause costly damage.there are a few things that will cause this issue ,could be as simple as a bad heater control valve or could be in the dash control unit. give acathor1 a pm he specializes in this
