Heat/AC Controller not working
Greetings! I just purchased a beautiful black 2009 CLK350 at an auction. The car is in incredible condition with 36K on the odometer. There is only one problem. When you adjust the heat/ac controllers nothing changes. The system is currently blowing out of the floor outlets only. The temperature adjustments work, and the unit blows cold when set that way. Is there some adjustment needed, or do I need a new controller unit? Any guidance would be appreciated. Thanks!
