'95 PT-42 Front Heater Question

1 - Ok I have dash heat and air like in any car or truck. But I also
have three vents on the bottom of the front consol, near the step
well. I thought that the thermostat that controls the front air would
operate one these vents, like the two thermostats in the kitchen and
bedroom, they operate the hydronic heat and A/C in those areas, but
it doesn't. The dash A/C – Heater operates the two floor vents over
the step well. But the third larger vent, more or less amid ship,
doesn't seem to do anything. I got my hand up in there behind it,
though the CB compartment and I couldn't feel any heater core of any
kind, or much of anything else for that matter. It might be like the
vents over the step well the heat just dumps into the consol area and
kind of pushes its way through the vents. Any help would be great! I
was told when I bought the coach that there is no heat up front when
the coach is in camper mode, only when the engine is running. If
anyone is curious there is a heater just under the sofa up front near
the drivers chair and it does a great job. I would just like one near
the door to offset heat loss when the family is going in and out 50
times a day.

2 - Also the temperature control slider on the dash is very difficult
to operate. I'm afraid that I will break it; it takes that much force
to slide left or right. I know the cable and hinges need to be lubed,
but I'm not sure what to use for lube. WD-40 need not respond;}
