Here is a pic I took this evening. This that I have circled in red was covered in about 3 inches of dry leaves/sticks, etc. After I got the leaves out, I started the car, turned on the A/C and this gets hot! That was likely what I was smelling when the A/C was on. It has a wire to it nad its like a ceramic box....



other pics after cleaned... all of this was covered in the bottom with leaves/sticks/paper....



Here is a pic I took a couple of months ago before I cleaned it....

this was a fire waiting to happen!




here is the battery side I took a few months ago (I have since unhooked that wire that went to the CD changer) - still need to clean that side I guess.
