Hello, did you replace the expansion valve and drier as well? what are your high and low side pressure?

Customer: replied 4 months ago.
I did that almost 2 years ago when I replaced compressor. I have around 35 to 40 on the low and 225 to 250 on the high

Hello and welcome to JustAnswer!

If the line temperature isn't dropping then you have a basic a/c system isue, if they were actually dropping yet it blew warm then actuators would be suspect.

The most likely cause for this would definitely be the expansion valve, there is a separate expansion valve for front and rear which will affect them individually.

When was the compressor replaced last? I would assume recently but you mention two years ago.

What was the issue with it when it was replaced?

Where did the replacement come from?
