Hello, 2016 Camaro v6. AC on working well then suddenly turns hot on both Drivers and Passenger side with a noise in the dash when this happens. Shortly later and it works well. I have been fighting this issue for years.
New and programmed HVAC controller, new relay, new low/high pressure switch, new thermal expansion valve. No data codes in computer.
Please help.
