The a/c in my car was blowing warm air and I figured it just needed a recharge. When I connect the manifold to the system I get a high side reading of 110 psi which rises to 150 until the compressor shuts off. Low side is down around 20 psi. I started to add Freon through the low side and the system took about 5 minutes to accept it. Now the high side pressure is at 220 psi and the low side around 40. The compressor keeps cycling on and off and the air coming out of the vents is just cool. If I drive the car the air gets warmer until I take my foot off the gas. The car will start to put out cool air at idle
Is the low side pressure too low? Does it seem that there may be a clog in the orifice valve? I’m assuming the air gets warmer when driving due to the compressor cycling off because of too high pressure. Is this correct? What’s my next step?
