[Rovernet] 3500S Heater resolved for now

[Geoff McCarthy]

Jim, the valve that I have is a NAPA valve for a Jag, I think.  Buy one,
test it with a hand-held vacuum pump to make sure it opens with vacuum (some
close with vacuum!) and put it in.   Mine works off-on but probably could be
modulated by restricting the vacuum input source.  If too hot, I just turn
it to the a/c side!

Thanks for the helpful info from all who responded to my plea for a warm
3500S this winter.
After perusing your suggestions, I spent $5 on a right angled heater hose
adapter to replace the vacuum valve and - Voila! - I have heat!
Of course, it is the on/off variety that Geoff McCarthy has, but, hey, it's
winter. If we get a warm day, I'll just roll the windows down!
Last night I was driving in 35 degree temps, and I was toasty warm with the
fan on medium. So I guess the used vacuum valve was the culprit after all.
So next Spring, I'll just replace the adapter with another vacuum valve (if
I can find one) so I can have AC for the summer days.

	Again, thanks for your responses.
