I have a 1993 prelude and none of my climate control buttons work and I really would like to fix it, I, not sure where to even begin on how to fix it. None of the buttons light up and that has led me to think that something might not be hooked up. If anybody can help I would appreciate it a lot.

 

Did you even try a search?

This has been addressed many times and resolved many more.

Take it apart, resolder the circuit board where the harness plugs into it.
