How do you determine if your Actuator, or heater temperature control, is bad. on 1996 Ford Crown Victoria

I have narrowed the problem down to either the heater temperature control or the actuator. How do you determine which is the problem. Can a bad temp control swtch, be determined by a specific means, or do I just change them both. HELP, three winters w/heat issues.
