So this happened several months back and turning the car off and back on fixed it. This time, nothing I've done has fixed it.
I'm driving to work this morning with the AC and recycle air blowing on me at the coldest. I press the button to turn the air up a bit and this switched the AC and recycle off and moves it to defrost. Turn off defrost and it moves it back to AC/Recycle and blowing on me. Ok, turn off AC > switches it back to defrost. Turn off defrost, back to AC. Turn off recycle air > back to defrost. Every button turns on something else and back again. I've turned off the air, I've restarted the car several times once I got to work. I'm not sure what else to do or what's causing this.
