Heater control wiring diagram

What is your question?

I am looking for what the wires that plug into the heater/ ac controls do. I have a bad unit and need to bypass the hot cold switch somehow to blow heat. I cannot afford to buy another switch for a few weeks and need heat!! The fan works, the area selector does not, nor the recirculate or the ac on switch . i know i prob need a resistor, but what value and what wires? Thanks
