Hey everyone. I recently replenished my A/C refrigerant. According to Datamaster, I have pressure in the line at about 32 PSI at idle without activating the compressor. I switched on the compressor and the pressure increased to about 145PSI - 185PSI depending on engine RPM. The system did not cool the air and this was also corroborated by Datamaster as the sensor read 90* F. Any ideas?

 

whats your suction pressure

 

The pressure reported on the gauge that was attached to the can was around 40PSI. I don't remember the actual pressure but it was listed as "good" on the meter.

 

feel the return line on the system or the big silver cylinder coming out of the firewall. is it cold?
