    Question 2005 Expansion Valve Location

    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!

    You need to put a good vacuum on the system, and weigh the charge in, without running the system. It wouldn't matter what setting the units are on, since the pressure switches would cycle the compressor, on and off to maintain the ccorrect pressure in the system anyway.

    Sorry, can't help with the expansion valve.

    But, the warning about the rear heater system is about the specific air bleeding procedure required after replacing the coolant. Following a routine burping procedure could leave air in the system.
