What’s the temperature of the rear liquid line both before and after the expansion device compared to the temperature of the suction hose? How high is the frost line on the accumulator?

The accumulator is the cylindrical looking thing in the suction line under the hood. The level of the “sweat” on it can give some indication to the state of charge of the A/C system. If the front A/C is working perfectly well then you likely have a stuck expansion valve for the rear unit.

Yeah the frost level is all the way to the top. I kinda had an inclination it was the expansion valve bit I wanted to get someone else’s opinion. Thank you I appreciate it.
