Keep every fan setting on your Mercedes-Benz climate control working with the Beck/Arnley HVAC Blower Motor Resistor 204-0079. This resistor regulates current to the blower motor so the fan can run at its various lower speeds, and it drops in as a direct-fit replacement for a wide range of Mercedes-Benz cars — including the 1996 C220, 1997-2000 & 2002 C230, 1995-2000 C280, 1996-1997 C36 AMG, 1998-2000 C43 AMG, 1998-2003 CLK320, 1999-2003 CLK430, 2001-2002 CLK55 AMG, 1998-2004 SLK230, 2002-2004 SLK32 AMG, and 2001-2004 SLK320. See the Buyer's Guide tab for the full application and engine list.
If a failed blower motor resistor is the cause of a fan that only works on high speed or won't run at certain speeds, this part replaces it. Diagnose the cause before ordering, as those symptoms can have other sources.
