Has the climate control fan in your Mercedes-Benz lost some of its speeds or stopped working all together? The blower motor may not be to blame, but a failed regulator could be the cause.

This regulator is used to feed power to the blower motor to adjust the speed for your automatic climate control. If this regulator fails, you may be left with a non-functional blower motor.

This regulator is located on the side of the air plenum on the blower motor housing.

For vehicles with automatic climate control

*Due to chassis splits and option codes on some models, please verify fitment of this blower motor regulator with your Mercedes-Benz prior to ordering*
