While most people are already aware that you have to select a specific temperature on your thermostat. The furnace will then keep your vehicle adjusted to that.

However, what they might not know or have forgotten is that the temperature has to be higher than your room temperature.  If your selection is the same as the temperature in your room or lower than it then the furnace will not work.

It might still blow out air depending on your fan settings but it should not have any heat in it. Considering this, simply adjusting the thermostat in your vehicle should allow you to fix the problem you were getting.

In some cases, the thermostat can also get damaged or its connections can come off. You will have to check the device for this but make sure that you switch it off beforehand. This will keep you protected and will also make it easier for you to check the wiring. If you are still confused then consult the manual provided by Atwood to help you out with finding the wires for your thermostat.
