2009 Edge, Mice getting into blower motor

[dallasgeezer]

2009 Edge, mice are getting into the AC/Heater blower motor and getting chewed up. Where is the inlet to the outside air?

I can't find it on the firewall. I want to put some screen up to stop the vermin.

Thanks

When your looking in the engine compartment, look on the cowling and you'll see the PCM (has three large wiring harnesses connected to it).

 

Reach UNDER the cowling, (under the PCM) and you will feel a felt-like pad covering the bottom of the cowling.

 

That's where the air intake is located (air drawn in through this pad. (I think).

 

Because the back of the PCM is installed in this duct,  I think they are using the intake airstream to cool the PCM and then its drawn into the hvac cowling through a rectangular hole in the dashboard (or more properly, firewall inasmuch as the dashboard is actually the steel part angled up at a 45° angle where your feet go).

 

If you getting mice in the blower motor, they are inside your engine compartment. Probably chewed a hole in the intake pad. Check ALL of your engine wiring as they love to chew on pvc insulation.
