Had AC compressor replaced last month day before 3/36 warranty expired cause vette tech said it was leaking month prior when hie was replacing wiper motor.
Yesterday was filling with gas b4 putting baby to sleep until March/April decided to give A/C a quick work out with temp set to 63 and got really hot air.
lowered it to 62 and same situation,when I set it to 61 then blew cold.Repeated same process just incase a fluke but same result AC only blows cold at
61 at 62 and above its a furnish. ???? Thank god for extended warranty
My ‘17 Z51 is at the dealer right now because it almost always blows hot air out the driver vents and cold out the passenger. Don’t know what the fix is yet but seems like something is awry with whatever mechanism mixes cold and hot air streams in the HVAC system.
