The car has 169k miles on it and about two years ago I was driving on the highway with the a/c on. All of a sudden there was a forceful blast of a/c with a chemical smell then the fan, a/c, and heat was shut off and the dashboard screen for just the temperature area was turned off. When I push on any of the buttons in that area nothing happens.

Is this an expensive fix? Can I fix it myself? If it’s an expensive difficult fix are there any good alternatives for a/c in my car for the upcoming summer? Thanks for your input!
