RV Repair: RV Comfort 2C Coleman March Theromostat, zone 1, motorhome

Question
Our thermostat in our Motorhome is not blinking between zone 1 and zone 2 continuously and we are not able to use the heater. What does this mean and how can we remedy the situation. Thank you very much.

Answer
Julie, I will need more than what you gave me to answer this for you right. I need to know does the ac work? Also if you can pull the T-Stat off and look and see what kind of connector they have on the back. This will help me diagnose the trouble. Thanks, Bill
