Take control of cabin comfort with the Four Seasons heater control valve 74941, a rotary electronic heater valve that regulates the flow of engine coolant to the heater core to help manage interior temperature. It installs as an application-specific replacement for a wide range of Mercedes-Benz models, including the 2016-2017 Mercedes-Benz Maybach S600, 2012-2013 Mercedes-Benz S350 and 2014-2017 Mercedes-Benz S550 — see the Buyer's Guide tab for the full list.

  • Electronically controlled: an electric valve that adjusts coolant flow on command from the vehicle's climate system.
  • Temperature tested to 270°F: checked to hold up to high operating temperatures.
  • Pressure tested: verified for a leak-free design.
  • Application-specific design: built to the requirements of the listed vehicles.

This valve features a plastic body, four connectors, and a bypass-style operation. If a failed heater control valve is the cause of your problem, replacing it can address symptoms such as little or no cabin heat, cabin temperature that won't adjust, or coolant seepage at the valve — diagnose the cause before replacing, since these signs can have other origins. Backed by Four Seasons' decades of mobile A/C experience.
