One common problem that many people have reported is the build-up of hot air in air conditioning units, which can be troublesome for homeowners. Additionally, a lack of adequate airflow can lead to issues such as mold growth, damaged seals, hoses, or ventilator fans that may need immediate replacement. Your AC might initially blow cold air, then switch to emitting hot air due to problems like a blocked expansion valve, issues with the compressor clutch, or a blown fuse. Leaks are another significant concern, as well as potential bad smells from a dirty air filter or moldy evaporator case. It's important to address these issues promptly to avoid further complications.

In my 2012 Buick Lacrosse (3.6), the air conditioner suddenly stopped cooling, even though the compressor clutch can be turned by hand without resistance. While the car is running and the A/C is at maximum, the clutch does not engage, and the Freon levels are normal. I want to inspect the pressure switch but it's not the usual 2-wire type that can be jumped to test clutch engagement. How can I test the 3-wire A/C pressure switch on my 2012 Buick Lacrosse, or could there be another underlying issue causing this problem?
