E-Class (W210) Mercedes Blower Motor Regulator - If the regulator fails, which is usually due to overheating, the blower motor fan will not operate faster than +- 50% power. Mercedes updated the regulator to improve its reliability, but the redesigned regulator requires the installation of a new blower motor, regulator and mounting bracket - usually a set back of anywhere from $500.00 to $800.00 in parts. The old-style regulator is only compatible with the old style blower motor, and is no longer manufactured. The blower motor regulator may be replaced with the much less expensive W140 S-class blower regulator, provided that the E-class wiring harness is re-attached to the S-class regulator.
It is important to change the cabin filters regularly, because if air is restricted from circulating into the blower motor compartment from a dirty clogged up cabin filter, this will cause the blower motor and other components such as a blower regulator, blower resistor or ac final stage unit to overheat and this will be an expensive repair, which could have been avoided by replacing the cabin filter/s.
