Hi, all! Does anyone know the location of the a/c expansion valve on a 2005? I replaced my compressor and drier, but couldn't locate the expansion valve. Recharged the system myself, but now the a/c blows warm when the car is not moving. Did some googling and think it may be because I didn't replace the expansion valve. Also...does anyone know why there's a caution sticker about replacing coolant when you have a rear heater? Oh, and when checking the a/c pressure, should the back a/c be on low and the front on max? Thanks in advance for the help!
