Good Evening all from Sunny South Florida,
I have a 2012 Kia Rio5 EX with about 108k miles. I have noticed that when the AC is on low between 1&2 the pressure behind the air starts to decrease, if I turn it to 3 or 4 it makes noise as if the system is clogged. I come from a line of residential AC mechanics, the first thing I checked was the High and low sides, and the system is fully charged. I do not see any ice on the lines going to the condensor. but I do have a substansial amount of water dripping from the car in the garage once it’s parked. I am thinking it’s freezing somewhere but Im not exactly sure where to check. I have replaced the cabin filter, and the air cleaner for good measure with nominal improvements. It’s worth noting it has occured once while utilizing heat instead of cooling,. I am hoping someone can take the time to help me diagnose the problem. I do not have a warranty on this car, and would like to attempt to fix it on my own. I am willing to pay for anyone’s time to help me with this issue via any digital payment method
P.S. The AC never gets warm unless i utilize heat.
