chassis heater problem

[Robert & Teri Rahn]

I have been trying to figure this situation out for several days now
and cant seem to solve it. The chassis heater under the sofa up front
and the dash heaters do not blow hot air, All the other ones work
great. This morning I replaced the two sporlan valves in the back
with manual valves to make sure they werent the problem and they
werent. The auxillary pump works and runs but is it possible that it
is not working good enough? I thought that there may be air in the
lines up front so I installed a valve with a female hose connector in
the wheelwell under the sofa chassis heater. There was a lot of
coolant in that line and it was quite a mess to put it on. I did put
hose pressure on after I installed it and it quickly started to
overflow out of the coolannt cap that was removed. I located a small
bleed screw on the line below the dash heater and coolant sprayed out
of it as soon as I loosened it.

What should I do, im sure puzzled. Should I put another t in
somewhere with a valve on either side and then hook the hose to it
and shut one side then the other to clear any possible blocks, or am
I overlooking some component.
