Well here is what I found so far which I must admit is a little confusing.
DC volting at the valve connector and with the temp dial clicked at Blue, with koeo gives me constant ground as Steve suggested. 12.6V to be exact.
with dial clicked at red I get what I would describe as fluctuating numbers - from 4V up to 30V at one point. When clicking back to blue, we go back to constant 12.6V - I Tested both valves with the same result.
This follows the logic brought on by steve and indicates that everything is good.
Taking the car on the road however, is a different matter. The system starts properly with no heat and then provides it when requested. The problem seems to be when trying to shut it off. I click the valves to blue, yet some heat keeps coming into the cabin - with, or withour blower.
Why would the system that seems to operate correctly when stationary and cold, not work when moving and hot ?
Is it possible that I am barking up the wrong tree ? That I might actually have a problem with the flaps and they are directing engine heat to the cabin ? Or am I way off...
