I finished the valve cover gasket in it, and all is good but I noticed ac was not working, compressor not kicking in. Checked the wire and its connected. I tried to charge it with Freon, and it keeps reading 5 PSI, where is the relay for the compressor so I can try to lick it on while charging? I did not have any leaks while working on the car, weird. But it was running. A/C was cold before. Car been sitting for 2 months almost. Fan comes on when A/C button is pushed.

Here are the codes. I pushed the pin in the charging port and there is nothing, no Freon at all.

Hi,

Are you sure the Schrader valve was released after you let go of it? Also, something is likely happening at the connection between the low-pressure valve and the freon supply. Otherwise, it would take more than 5 psi. I'm not sure what you are using to recharge the system, but are you sure the product connection is good? Are you sure the freon supply is not empty?

Let me know.

Joe
