Defroster woes - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Well, the new 350 is running strong. A bit more cam than I would have picked myself for a street engine, but I can live with it. Sure does like that premium gas!

But, with the good comes the bad. I recently re-cored my heater core and the heat works awesome. The only problem is that no matter where I move the top lever, I only get heat from the center A/C vent (yes, it has factory A/C). I can see the cable moving the lever on the front of the Mysterious Black Box directly below the controls, but it doesn't seem to change anything.

Anybody here have an idea before I have to walk out in the 15 degree weather and tear everything apart? Frankly, I'd rather have a good defroster than a blast of hot air from the center vent. Seeing comes first, ya know.
