I have a 2015 Dodge Dart GT 12,500 mi. that the AC is not blowing as cold as it should. When the car was brand new, same problem, I took it to the dealer who said at first there was nothing wrong. After another six months went by the AC wouldn't blow cold air at all. Took it back to the dealer who said the manifold connection to the compressor had been leaking and they corrected the leak and refilled it with refrigerant. It then worked fine for another 2 years. Now it's not working again. It does blow some cold air but not nearly enough on really hot days (80°F and above). I checked the manifold connections at the compressor and the condenser and they are both fine. I have not put gauges on it yet to see what the high and low side pressures look like. Also, the AC blows warmer on the passenger side than it does the driver side despite the fact that the dual climate control is set to the same temp on both sides. Any thoughts would be appreciated!
