No climate control and fan always blows hot air

Sounds like your car took a pretty hard hit at sixty mph, do any of the controls on heater/ air conditioner control assembly work? Or interior lights work? And one more quick question, can you check to see if both of your cooling fans behind the radiator are on? By looking at the wiring diagram, the air conditioner request is sent to the PCM itself. Which is located in the air box assembly in the front of the car. I know that is a strange place for it to be but its the same on my Impala. So just a few questions to get some more details first.

You might also test all your fuses with a test light with the key on before you get too deep into testing.
