I replaced 3 blend door actuators so the vent system seems to be working fine. The compressor comes on when I press the A/C button on the dashboard. The low side port shows 50 psi. There is no difference in the air temperature whether the compressor is on or off. Please help. Thanks, Fred

Good afternoon.

I need both pressures, the high and the low side.

50 on the low side is too high. I assume you are using one gauge on the low side.

Can you get a set of gauges and give me the readings?
