TX valve is the one where the temp switch in the cabin moves lef to right when u switch from hot to cold right? If so, then that is working. Ive also tried moving that manually by hand and the cold air still doesnt get into the vents.

Had a mechanic check the gas level and compressor and he said it was fine... the pipe that goes to the front bumper (in front of the radiator) is cold BUT the pipe that continues from there is just warm... is that where the evaporatour temp sensor is located?
