Need help understanding the function of the thermo switch that is screwed into the rear passanger side head of a 350 small block chevy. This thermo switch runs on the Heater / AC wire harness. On an AC car, the switch breaks the solid yellow wire of the harness. On a non-AC car, the switch breaks the Black / Double Yellow Stripe wire. I think in either case, the Yellow or Black / DBL Yellow wire runs from the dash switch to a resistor assm for the blower motor. The switch is open when cold and closed when hot. Can this switch be eliminated without much problem?
