Blower Switch
WARNING: This page is about a different car, the 1996 Mercedes-Benz C280 and 1996 Mercedes-Benz C220. However, it is still accessible from the selected car via links, so may be relevant.
Push buttons provide varying speeds. When maximum fan speed button is depressed, only highest blower speed is available. When minimum fan button is depressed, only lowest blower speed is available. If automatic push button is pressed, system operating mode will use blower speed determined necessary.
In any operating mode other than defrost, blower will operate at second lowest speed after a 10-second delay. Blower will remain at this speed for approximately 30 seconds, then will move to other speeds as required.
