Blower Unit Component Replacement

WARNING: This page is about a different car, the 2008 Honda Pilot, 2007 Honda Pilot, and 2006 Honda Pilot. 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), the power transistor (B), and the blower motor (C) can be replaced without removing the blower unit.
Before reassembly, make sure that the recirculation control linkage and doors move smoothly without binding.
After reassembly, make sure the recirculation control motor runs smoothly (see RECIRCULATION CONTROL MOTOR TEST ).
