My CX 7 AC seems weak. . AC on non-recirculate, temp and fan control on maximum and a window cracked. This from an 1995 AC manual on how to check system. Outside ambient temp is 92 F and a digital thermometer 2 inches into the upper center vent gives a cooling temperature of 62 degrees F. According to my old AC book for R-134 refrigerant, the outlet temp should be 39-50 degrees at an engine rpm of 1500. Does anyone have a Mazda factory manual that provides the AC operating conditions with respect to ambient temp? Thanks so much. Ed Hayes
