As long as you know the make and model numbers, you can go to You Tube for a tutorial. They can walk you through it step-by-step.
Sounds like the thermostat is working if you can see when you switch from heat to cool. Could be your ac unit. This happened to me. I took the panel off the ac unit and discovered the capacitor was burnt out. Replaced it and all was fine.
