Ok - thanks! That is quite helpful then. I wondered exactly what the switch
on the left was for. It's marked poorly and the picture makes no sense to
me. (And this coming from a graphic designer, LOL).

Nope, no owners manual, unfortunately. Been looking for one but they seem
pretty hard to come by.

There does seem to be another leak in the rear heater lines somewhere and I
have yet to find it. I can smell antifreeze/coolant when it gets warm and I
keep having to add a little coolant every week or so. It's obviously a small
leak, so that's fortunate in some ways, but it's dang annoying! Nothing
under the rear seat is wet so it's not located there. It doesn't seem to be
in the engine compartment and I don't see any drips or puddles under the
van. Any thoughts on where else to look?
