Hello. I am having a problem with a car I just bought. OK
I turn ac on and the compressor turns on, the fan turns on. the air is hot. I drive the car and at higher RPMs it does cool a little. I tried to add 134A and the gage is maxed out on the low side. I rev the motor and the gage pressure goes down some. At idle its all the way in red pegged out. compressor is on and working and the fan is working. Whats going on?????? Thanks

#1) Get an a/c gauge set to monitor both the low AND high side pressures.
#2) Get an a/c gauge set so you know what the high pressure is doing BEFORE adding refrigerant. What you've done thus far is a great way to blow off a high pressure line and hurt yourself in the process.
At this point, you have an unknown quantity of refrigerant. Pressures definitely help and can point toward a likely scenario, but an even better thing to do is start with a properly charged system before attempting to diagnose the problem.
High pressures and poor cooling spell air in the system. Then if your system was out of refrigerant, if that can leak out, air can leak in changing that PAG to sludge.
Nick, I dont get it- how can air get in if theres at least SOME pressure inside? (assuming there had to be at least a tad of refrigerant in there)
