HELP ! Scratchin my head !!!
 

How do I access the selector switch / knob > AC / vent / etc. ? Mine will not go to vent , works in other positions. To hot not to have vent not working. Cold weather gonna need the defrost too. I've tried to access from either side to no avail. Do the cover panels just pry off ? Is this a cable type issue ? Where do I start and what will I find ? Please and Thank You for any insight . 2008 XD.
