Dirt/Debris in Heat Blower

I had send my car ( Accord 2001 V6 EX ) for 75000 mile servicing. The
Technician informed me that there was some debris/congestion in the
heat blower of the car, and it is possibly due to a rodent like a rat
or something who has been stuffing things out there . To clean this up
however the estimate is for $550. Has anyone encountered such a problem
and is this estimate ok for a such a problem .

 

---------------------
Use google to search cabin filter accord, and get the replacement
instructions, then open it up yourself, and also drop the heater motor
out (unplug connector, three Phillips screws) and use a piece of coat
hanger and an air hose to clean it out. Have a new cabin filter (or are
there two?) from NAPA ready. An hour of fun and learning, save $500.

I have a nissan that sat arouns a while until I finished the engine
work. When I started to drive it one rainy day the heater motor sounded
like the bearings were going out. Turns out the local mice had been
using it for a bedroom and the fan was FULL of "debris"

Pulling the fan on a honda is usually just annoying and not next to
impossible like most US cars. I cant see $500 being a realistic estimate.
