Hello Johndfw.
Yes I Installed A New Heater Control Valve First. I Now Have Some Heat But Not Like When I Had No Problem.i Think I'm Going To Buy A New Bcm & Prom To See If This Will Work.

My BCM is not working either. The fan doesnt work at all. Replacing the BCM in your case might work. I'm not really sure how that thing works.

Good luck
