on the AC, how do you turn it off ? Pushed the button but it stays on.
Ran the test, had 5 codes, erased them, works fine. They were 1231,1232,1233,1241 and 1459.That means that your compressor is not running. Run the CC diagnostics and if you are low on refrigerant you might try adding some. But your best bet is to have your CC serviced (evacuation, leak test, proper refill) by a competant AC shop.
