2 days ago I was cleaning out my car and killed the battery by having radio going for way too long. It jump started easily and has been starting and running great. BUT--the touchscreen is now very wonky. Some buttons work, others don't do anything when pressed. In addition, the control panel for the climate and radio(just below the touchscreen) will not work at all--no lights and no beep when buttons are pressed, and the volume dial is no functioning. The fan is blowing very warm and on highest speed and nothing that I've tried will allow me to adjust this. I would like to at least troubleshoot the issue myself before taking it in to a shop for repairs I can't afford. Anybody have any ideas? This is my first visit to the forum and from what I'm reading, there are some really bright people here who might be able to help me.
