HI,
What is the high side pressure reading and low side pressure reading in psi
does the compressor cycle on and off quickly
how do the lines feel at the firewall where they go to the evaporator
Customer: replied 1 year ago.
Can I get back to you on this a little later in the week?
Expert:  Eric replied 1 year ago.
HI,
yes, that will be fine
Customer: replied 1 year ago.
Eric Sorry it took me so long to get back. The low side reads 110 psi and the high side reads the same. The compressor is not cycling, and low and high side pipes are ambient temperature. No cold air. I replace the orifice tube and the ac pressure switch (the one next to the high side port.
Customer: replied 1 year ago.
When I say the compressor is not cycling, I meant that is is engaged all the time.
Customer: replied 1 year ago.
Also the ambient temperature is right around 95 F.
Expert:  Juan Crespo replied 1 year ago.

hi there. Different expert here.

110 psi on both hi and low sides with the clutch engaged means the compressor has failed and needs to be replaced.

Please let me know if you need further assistance with this issue.

Best Regards.
