Hi All,
Could someone please let me know how to reset the heating vents on my 2001 C320.

I found this worked on my S203 (2005)

Switch on ignition. Don't start engine.
Press recirculated air and defrost buttons on control panel simultaneously and hold for longer than 5 seconds.
The LED's in the defrost and recirculated air buttons will start to flash alternately.
Wait until the LED's stop flashing (approx 30 sec) system will rest set to defrost LED on.
Switch off ignition.
After 40 sec re start engine.

If the leds continues to flash for more than ~30sec, the system cant reset and will need to go on STAR
