Sounds like you have Autoheat see Autoheat Explained
It could be your interior temp sensor. Or the heat valves on the heat exchanger could be frozen open. Does your fan still operate at different speeds? Ian

It has to be the heater valves not closing.
Either the thermo doesn't activate them because it's toast or (more likely) the valves are corroded. The servo (It is hooked up in the console & operating, right?) pulls or releases the cable which moves the other cable which operates the valves which are spring-loaded (closed is the relaxed mode).
