    Sudden inability to use heat or air conditioning. Display panel does not toggle to exterior temperature. Thought it was a fuse, but this does not appear to be the problem. I have no answers.

    i had the same problem, i got a can of that electrical parts cleaner, for wires and stuff. i cleaned every fuse and the fuse box under the hood. i could not figure out which one may be for the ac so i cleaned them all. i let the car sit a little while so the cleaner fumes could go away then started it up and turned on the ac. works fine now.
