My 1998 Lexus GS 300 is blowing hot air. The "freon" is full. The clutch is working as well as the fan. I tried to find the expansion valve to check whether the line is hot before and cold after but I am unsure if I found it. I found one object that may be it, and, if so, this may be the problem as the line before is warm and the line after is just an itty bit cooler. The temp gage does not show car is overheating. I tried to find the evaporator to check the temp of the lines. Can you provide any other diagnostics I could perform to determine the problem? Also do you have a diagram so I can figure out where everything is located. Also, can you tell me how to remove the filters so I can check them? Thanks so much for your help.
