thanks & new ? about chasis heat

[Robert & Teri Rahn]

Hello, Thanks for the replies about the problem we were having
with "no hot water" It was the switch that is on the side of the bed
that had gotten flipped to drain by some curious children Now that
that is all working, we are trying to figure out the cold chasis heat
in the front of the coach. The rear works great - plenty hot, but the
front (dash and under the sofa) blow out nothing but cold air. Any
ideas/suggestions? Looks like there are 3 valves in the rear and they
are all turned the right way. Anything we are missing? Thanks so
much!
