Not as ignorant about them as I am!
I have not ever had it apart yet, and I don't know how it functions beyond the switch cluster, like if there is a problem with the "blend door" or whatever connects the switch to the "blend door"... I do know it all looks like flimsy plastic.
I have located a cheap switch cluster.. Maybe I will just order that, and see if it helps. Is the swap pretty easy? It just looks like pulling the bezel and plugging up a couple wiring harnesses..
