Our vents are blowing just air. So assuming it was the refrigerant, we went and bought a pressure gauge/refrigerant kit called cool air. Our compressor spins on and off about every 5 seconds or so. So we tested the pressure, with the car running and ac off, the pressure is about 65-70 ... When we turn the ac on, the pressure moves up slowly and just when it gets to about
55-60 the compressor spins and it immediately drops to 0 then when the compressor shuts off it starts climbing again. The kit not come with a fitting for the high side, Im hoping this information might shed some light on what the problem may be. Any insight is appreciated. Thanks, Nicki
