The light on your A/C button starts flashing after about 30 secs and your not really getting cold air. My HVAC has been messed up since i got my car, passenger side blows cool air in the winter when cranked up to 78, and blows luke warm air when it's on A/C but today was the first time this problem occurred. It was about 80 today in NY and the A/C worked perfect all day until my ride home when this blinking A/C light started and the air turned cool, NOT Air Conditioned to be cold. Anyone????

 

check the relay or somthing cuz it seems like that wen i try to unplug the relay or harness from the engine bay..my ac light start to blink and the fan kit on
