On my 04 non turbo 4.7 pt. I am having trouble with the a/c not taking
any freon, I have the hose connected to the low side. The compressor is kicking on and off while the a/c is on. I noticed that when the cooling fan came on the air would get cooler and when the fan shut off it blew warm air. I have a R-134 recharge hose with a gauge handle. The needle would go over in the red meaning overcharged and when the cooling fan comes on the needle would move down in the green sayin filled. I hope someone can make some sence of what I'm trying to explain. ![]() |

My first take is that you don't have enough r134 in the system to keep the compressor engaged. The low pressure switch keeps turning it off. You have to jump the low pressure switch to keep the compressor turning to fill the system.
