I am having the same problem.. I have already had to replace the intake manifold gasket cause it was leaking, still no heat. We will be flushing out the heater core to see if that's the problem. I may have to replace the heater core, we will see.

go to website coloradok5.com and look in their tech section. they have very detailed instructions on changing a heater core in a Blazer....should be exactly like your suburban. its kind of a pain but worth the money you'll save over paying someone else to do it.
The shop manual requires the removal of the dash assembly. If you consider yourself mechaniclly inclined go for it but it's not for the faint at heart. If it's plugged up and not leaking have you tried flushing it?
The heater door control on a Blazer can be replaced by purchasing a new one. The heater vent will pop out with a little nudge from a flat tipped screw driver. Then insert the new heater vent door control.
