This is the "heat sink" looking pack that sits behind the glove box, and fits into the evaporator assembly. It's black and has a silver metal "heat sink" on it with an electircal connection.
I was testing mine letting it dangle there and I let it run too long and it overheated, and now doesn't work. (It has to be in the "box" to keep air across it).
If you have one shoot me an offer. They aren't that $$ new, but I figured if I can get a used one, so be it.
