I recently had an HVAC blower issue and I remedied it. I now have an issue where only the front passenger gets cold air when climate control is set to 60. The front driver as well as the rear controls only get warm air. I wouldn't even know where to begin as far as searching goes so I post my question here. Anyone know what is wrong?

From recent threads here on similar topics, it could be just a little low on freon or you have an air mix system problem. Do you have any DTCs from ACM?

Yup, that is a symptom of low refrigerant in a dual zone system. Usually not low enough to set a DTC.

Well you guys were correct. I bought a recharge canister and checked it out. It was borderline low. I filled it to right at the top level of fullness and it is blowing cold again. The passenger side air is still several degrees cooler but I will stay cool while driving this summer.
