Ac not getting cold enough

[justin0943]

Ac problem pulled vacuum held great recharge with 1.6lb of r134 the low side reading 40psi the high side reading 225 or so psi it's stable it's was 90f outside according to the manual it should read 30-40psi and 250-350psi could my compressor be going out it gets cool but not ice cold when driving at idle is a little worst always have to keep the fan speed on 3,at idle the air coming out like 55-60 degrees, also when holding rpm around 1500 the low side goes to 20ish psi and the high around 350ish psi.when turning off the ac it's pretty quick to balance the pressure also hear a hissing sound I'm the ac lines

This is a chart you can use to determine if the system is charged correctly or not.



At least you did get it working.

You did change the cabin air filter too right?
That can affect what you get in the cab while your AC is in use.
