I think it's all electric! I've already replaced the blend door actuator! And that didn't fix it!

I have the same problem. I replaced the blend door as well and still no defrost. Mine also makes a ticking sound when i start the truck. Still not sure what to do.

The ticking sound is from the blend door actuator... the teeth on one of gears are stripped off... You can purchase a new one, or do the same thing I did... as when you open the little actuator up, you will see that it only uses one side of the gears... I simply switched it 180°, gave it new teeth to run on, and it's still working after 3 years.
