Hi, the thermostatic expansion valve or txv is the metering device located in the liquid line. Its job is to meter refrigerant ( freon ) into the evaporator coil that is sealed by your fire wall and cools the auto down. This auto doesn't have the orifice tube that refrigerators use!! This txv would have to be plugged up at the screen to not meter freon into the system. I doubt its the txvalve. What I would do, is determine if the compressor is running and pumping freon through the system. You say it has a full charge, how was the determined? The compressor would have to be running. Its a pump under the hood that your serpentine belt goes around, and has what is called a clutch plate on the front of it. With the engine running, you can have someone set in the seat while you look under the hood. This pump has 2 aluminum lines coming out of it and the belt is on it also. Have the driver turn the a/c on cool high and you listen and look at the belt on top.It will be turning with the engine running and as soon as the a/c is turned on, you will hear this clutch engage on the front of the compressor, and loud click as this clutch will also start to turn. If it doesn't turn, the compressor is not working due to maybe a blown fuse, no freon and its off on its low pressure switch. If you know the compressor works for sure and the clutch is engaged, then you may have a problem in the expansion valve. Drop by a shop, go by auto-zone and have one of the guys look at the compressor and tell you if the clutch is engaging. You need to find this out. If its not, the fuse that's located in the electrical box under hood, its marked, will have a 30 amp fuse in it. I would personally drop by a auto shop and just ask them to tell you if the compressor and clutch is engaged when you turn it on. This would be the best thing to do, and then go from there. If its working and blowing hot air, you do have a internal problem and it will need service. You can't do this on your own, it takes special training and equipment to check. Consentrate on the compressor first and let me know what you find out. We can go from there, and figure this problem out. This a/c is new. Please keep me posted on this.

Ac not blowing cold/low pressure too high and high pressure about the same as low pressure side/ compressor engages but no cold air

Pressure has built up in the system possibly from a clogged orifice tube/expansion valve. Replace the orifice tube/expansion valve, thenPull a vacuum on the system and recharge.

Where is the expansion valve located? The air conditioner is blowing hot air in front and rear units. I did put two cans of fr-ion.

Is the system full of freon ?
The rear ac uses an expansion valve, and the front ac uses an orifice tube. One system can work independently of the other.

What are the symptoms of a bad ac expansion valve

Condensers rarely clog. What it could be is that when it was recharged, air got into the system and may have to be bled out and fill the rest of the way with freon.

Hey I am haveing a problem with My 2500HD ac system. I have changed The Condensor, evaporator, and the Compressor. I have charged it to the correct levels. It blows cool air, but it doesn't get cold....

Did you change the Receiver/ Drier and the Orfice Tube/ Expansion Valve? The Receiver/ Drier takes moisture out of the system and the Orfice Tube/ Expansion Valve controls the Hot/ Cold air. If that is bad it may not be opening or closing fully which would not let your A/C get as cool as it supposed to.

Ac compressor does not turn on when car has been sitting & it's hot outside. Works fine in the morning.

either the freon charge is about 1/3 low, or the expansion valve needs to be replaced. Freon is getting into the evaporator, but not in great enough volume to cool the air unless it is coming in cool to start with. check your ac charge, and if it is full, then have it emptied, change out the expansion valve, and recharge it
