Biohazard

One more thing with the HVAC controller: if you look at the following picture, you'll see a white piece of cardboard sitting under the pushbutton arms. This piece serves two purposes: to reflect more light into the plastic buttons so they light up real nice and, 2: to keep extra light from spilling out under the dash.



Being made of cardboard this piece was as foul with mold as I expected it would be so it would have to be replaced. Anybody know where I can find one? Yeah, me neither. Here's how I got around it for fractions of a penny.

Gonna make my own out of tin foil folded over itself.



The foil will do a better job reflecting light back to the button arms and is not the sort of surface to, in any way, foster any mold growth

After folding it over, I've got a four layer thick sheet of foil.
I then cut the length down to match the cardboard piece.



A little more bulk trimming.



Working in some of the detail cuts. Also folded in the back end to get the depth right. You don't want to cut here or you'll have 4 separate layers of foil floating about.



Look carefully- there's a wide strip of clear packing tape folded over the front end for added reinforcement. Then I cut the notches with my X-acto.
