My apologies VV. You have asked me this twice now. All of the tests run above are with the dash cluster plug unplugged But just so you know I bought a new pigtail and bulb for the heater control (gray wire out from the cluster plug) and even when the cluster is plugged in the bulb doesn't want to light.
