Same prob here too... no heat at all. Got the dash pulled out right now and checked the blend door; it's undamaged.
I checked the manual temp control impedance and it looked good. The wires from the knob harness to the actuator harness are continuous and contain no shorts. The 12V+ and the ground lines to the actuator harness check out OK as well. So I have to assume that the actuator is fried.
Quintin, how do you get the actuator out? Looks like pulling the dash does not make it more accessible.
TIA,

[edit]
It took every colorful word in my vocabulary but I got the actuator out. Cracked it open and found out that it got some antifreeze when the original core sprung a leak back in October. THere is a lot of corrosion and some of the soldered joints are pooched. Tried to clean it up and resolder the joints but there is too much contamination... time to call the dealership, order the part and start the waiting game.
