The air conditioning is stumping me. When I turn on the air, I feel the engine RPM drop down a bit from the compressor kicking on. The fan is working fine, climate control unit displays everything correctly. I even tried a different climate control unit in the dash, still no cold air coming out. I have checked the system pressure and it's fine, even added a bit more R-134a to the system just to put it in the middle of the green area on the gauge.
Got the Durametric out and had it run a test on my A/C system. It was telling me before there was an issue in the climate control unit, that's why I tried a different unit. Now it's giving me this error. Not exactly sure what I need to do to fix this issue or if it would fix the A/C not blowing cold air? The heater works fine.
