Mercedes Benz Blower Motor Resistor Regulator - 1AHBR00091

This blower motor resistor is just what you need to bring your heating and A/C blower system back to good working order! On most vehicles it is mounted to the HVAC unit inside the passenger compartment.

Specifications:

  • Brand New Heater Blower Motor Resistor Regulator
  • Direct replacement
  • Built to strict quality control standards
  • 100% tested prior to leaving the factory
  • Older design - square style

NOTE: Mercedes changed the design of these resistors in 1999.  However, earlier models could have been updated to the newer design.  Please inspect your resistor for correct replacement

If you are experiencing intermittent stopping during use or the fan only works in one position this may be your solution!
