Hold the cabin fan speed you select with the Beck/Arnley Blower Motor Control Module / Blower Motor Resistor (MPN 204-0132). This OE-replacement unit regulates the current flowing to the HVAC blower motor, so the fan runs at the speed your climate control commands. It installs as a direct-fit replacement across a wide range of Mercedes-Benz models, including the 2003-2007 Mercedes-Benz C230, 2001-2005 Mercedes-Benz C240 and 2003-2009 Mercedes-Benz E320 — see the Buyer's Guide tab for the full list.
