So I just got the head unit installed, still waiting on speakers and rings. I needed to bed the brakes in anyways. I think this was the first time I've driven at night since I bought it and I noticed the HVAC was dark, everything else works, tried everything, disconnected the battery, dimmer works, must just be the panel is out. the AC still blows cold, blue led's light up, just the backlighting. Just ordered up a new HVAC control panel, $260 gamble, hopefully it solves the problem. here's the part no in case anyone else's went out B120P0021F. seems to be a common failure from a quick forum search.
