Heat? '86 PT_40

[pauleburgess]

I bought the bus when it was still 100F out. I know there are something like 9 heaters, but I can't seem to make any of them work.

I've got 3x Cruisairs (2 of them even work)-- these are A/C only, correct? These are controlled by 3 knob panels-- Off/Start/Run; Fan Speed; Temperature

Next I've got two thermostats in the bathroom, overhead, and one on the dinette back wall, and one in the bedroom. These should control the propane heaters, right? The fan should at least come on if I tell it to, right (I'd like to make sure it blows before I feed it propane.)

I've got an electric heater under the sofa (as well as engine water heat, and propane) that doesn't do anything when I turn the knob.
There are also two switches (high/low, on/off) mounted next to the engine water heat.
The electric in the bedroom doesn't even have a knob anymore.

I am set to Summer because of this under the kitchen sink-- and not being certain what would happen from that pipe if I flipped it to winter.. (note for the curious, my ice maker is located tailward from the kitchen, in the pantry area. This hose heads towards the sofa. I don't know of anything that would use water forward of the sink, other than the heater)

Anyone want to give some guidance on where to start on ANY of these?
