I live in St. pete on mlk jr. st n. Car is a 2000 Honda civic EX 2dr.

My a/c/heater unit will not work. It used to come on every once in a while so i know the mechanical parts (fan, motor, condensor) all work, but the actual unit itself will not turn on. it is something electrical.. and i don't know if its the wire harness or the a/c piece the harness plugs into. or something else. anyone have any idea?, I can come to you if needed. I just want to find out what i need b/c i have no a/c, heat or defrost.. so its a big pain in the ass right now.
I can take apart bezel in advance.
thanks.
Jason
