- E270 CDI Avantgarde W211
On my E270CDI Avant, W211, there is a central roller switch with divisions of blue on it.
The manual says its the cold air vent roller? What does this mean? I have tried the a/c on and off and both settings with this roller switch fully up and down. There seems to be no difference?
Any suggestions?
