Cold weather issues

couple of questions. My floor heat is not working. I have the breaker on and the temperature is set on the thermostat. But no heat. Is there a fuse or relay that I need to check? Can't find a drawing of this system.

Over the road heater is blowing cold air. As I remember from trucks we shut off the water from the radiator in the summer time. Is that the same procedure for this OTR heat an if so where is the valve?

Also am I correct that the Webasto has to be on for the heat exchanger in the water bay to work and keep the temp up above freezing?

Might check in your engine compartment to see if there is a shut off valve on the coolant line going to the front of the coach???

Not sure you have the same floor heat as mine but I had similar issue when we got the coach. I have two T stats, one for rear and one for front of coach. I had heat in rear but none in front. Breaker on, t-stats would illuminate but no heat.

I removed the front T stat and found the wire nut had come off the bundle of neutral wires and wires had separated. Fixed that and have had great heat for past 5 years.

You do have to have the Webasto on to get heat in your wet bay.

Also check to make sure the two vacuum operated control valves are working. Here’s a link to see one;

They’re up front on the sides of the A/C - Heater box. Sometimes the vacuum lines get pulled off.
