Hey guys, my wifes 2004 mountaineer (4.0) Front and rear AC has not really blown COLD air for a while. A buddy of mine pulled a vaccuum today and refilled it, but with the AC on max, front and rear, the low side pressure is reading about 115 psi, and the high side is reading about 105. My friend thinks I should change the compressor and drier as he has seen this before and that was the case.

Before I spend all that money I wanted to get some input from explorer owners, make sure its not something simple like the orifice tube. Admittedly I know very little about how the AC system functions so any advice is appreciated.
