Thanks folks, great to be here and working on my bus. Got it back from the shop today. They said they couldn't set the speed any higher because there was no place to plug their computer and that it was controlled by the pump (as if they didn't know how to turn it up a few clicks). They did create a loop for the radiator hose that bypassed the rear heaters (there were two) just behind the drivers heater. The heaters themselves were left in for me to remove (which I did very unceremoniously this evening) and I was given a warning to treat the wiring to them properly lest the dangling ends touch together and cause a short. Unfortunately my lack of patience got the best of me and I ripped out and cut the wires just to be able to throw out the damn heaters. I know, I know... big no-no, right? But if I keep the heaters switches in the off position at the control panel, am I correct in assuming that no power will be flowing through the wires in question?
Here's a pic of what's left of the wires:
and here's a pic of the control panel:
As shown, there are 2 switches for "Fan/RR Heater", 2 switches for "Fan/RT Heater", and a switch for "Fan/Passenger Heater". I am assuming that I should tape them all in the "off" position. Will this prevent the formerly back heater's loose wires from shorting out the panel? Advice on this matter would be greatly appreciated.
and here's a vanity shot of me grinding the seat bases and pretending that I have skills:
