thanks & new ? about chasis heat

[Mark Johnson]

I have an '88 WB with the same condition. I have not replaced it
yet, but there is mechanism near the front curbside under the bus
that the book refers to as a pump, but I believe it is actually a
solenoid valve. My mechanic says mine is corroded up and won't open
anymore. I think the summer/winter switch on the overhead dash
controls this. If you crawl around under the bus and find the
heater hose loop under the copilot area you should find the valve in
a metal housing with some wires attached. It could just be a broken
wire too.
