Rear Blowing Cold 4 Zone AC
I have a 4-zone AC system, but the rear vents only blow cold air, even when set to the highest temperature.
I don’t think it’s the duo valve, because when I command hot air through DAS, it works correctly and blows hot. However, when I set the rear temperature to high, it still stays cold.
Any idea what could be causing this? Thanks!
