I started trouble shooting issue today , and now the heater wont come on. Although it is hot out, shouldn't it start fan if set to 90 and inside coach is 80 degrees?
So at this point the thermostat doesn't run ac, fan or heater functions.
I assume if switch on t stat panel is set to fan on...... the fan that blows the cold air around to the inside ac roof ducts should run?
