I disconnected the negative terminal on the car battery in order to work on Installing a new radio head unit just to be safe. Upon plugging everything in and reconnecting the battery everything works fine including the radio, expect the hvac module.
Whats interesting is the A/C is still blowing and when I turn on the headlights the buttons on it glow orange along with the rest of the car. In position 1 the buttons glow and air blows, but no control. In position 2 the lights turn off and no control. The buttons don't do anything and no numbers display on the screen.
No check engine lights, car starts fine. If anyone has an idea how to reset the unit or has run into the this let me know. Thanks.
