Blower Unit Component Replacement

WARNING: This page is about a different car, the 2009 Acura MDX, 2008 Acura MDX, and 2007 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.

Note these items when overhauling the blower unit:

The recirculation control motor (A), front blower motor (B) and the dust and pollen filter (C) can be replaced without removing the blower unit.
Before reassembly, make sure that the recirculation control linkage and door move smoothly without binding.
After reassembly, make sure the recirculation control motor runs smoothly (see RECIRCULATION CONTROL MOTOR REPLACEMENT ).
