Blower Unit Components Replacement

WARNING: This page is about a different car, the 2003 Acura 3.2CL and 2002 Acura 3.2CL. However, it is still accessible from the selected car via links, so may be relevant.

Note these items when overhauling the blower unit:

The recirculaion 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 ).
