My AC controls on my dash just recently seemingly turned off. The controls don't do anything, and I have no power to the lights. They were kinda stuck on the last setting which was heat on the windshield, but I unplugged the battery and now I'm not getting any air. I checked fuses 10 12 and 14 in the cabin and 14 was blown, so I tried replacing it, and still nothing. I tested the lines going to the control panel and there is power coming from 3 wires.

For a little background knowledge my battery shorted out a couple of weeks ago and I assume it killed my AC controls. I had been replacing my sound system after symptoms of the battery failing started, and my car kept dying and having to be jumped every 10 or so minutes. I also did pull out the sync display.

My running theories are a failed climate control module/control panel, or the display had some sort of baring on the ac system. Any Ideas?

 

for anyone in the future with similar issues, turns out the non-navigation display (which I had cut the wires to ugh) had some sort of logic running the AC panel.
