cleaning out air ducts?

[sjaeger]

Is it possible to clean out the air ducts in my 307RKD simply? I think we may have a mouse that crawled in there to die

You can remove the vent covers by putting a small flat tipped screwdriver in the slot and prying the tab. Repeat on the other two tabs.
To inspect, get a USB borescope camera (check Amazon) and snake it up the duct work. I tape mine to a piece of electrical wire (difficult to push rope) to help direct it the way I want it to go.
