I too, have a 2000 Silverado (5.3L) with blend door problems. In warmer weather, the blend door gets stuck in the heat mode and I cannot use the air conditioning, plus the cabin gets hotter than Hades. Do you have this same issue BRich? Or did you before you replaced you blend door actuator and temp control panel?
In terms of blending the heat, do you mean that you try to warm the cabin somewhat while the control is in "vent" setting and you turn the temp control to a warmer temp (from the blue to the red) but all you get is cool air as though it remains in full vent mode?
If so, I have this same experience. I believe that this model was not designed to do that. My wife has a 2002 Trail Blazer and she can blend warm air into the cabin while in vent mode. I have never been able to on mine.
