    I have a 2001 Jimmy, had the heater core flushed, changed the thermostate and still no heat. Should we try to flush the radiator next?

Okay... First off I am no pro on fixing cars, but I did have this same problem. What I had to do is drain the radiator completely, then use prestone radiator flush to totally clean out the radiator. Once this is done go ahead and refill it with fresh radiator fluid. ONE BIG THING.... Do not replace it with DEXCOOL! This is a reddish orange color coolant, and is what caused you and me the problem to begin with. Make sure you use green coolant and mix it 50/50 or buy the premixed stuff. Like I said, I am no pro so I had to look up exactly how to do this. It took me around an hour and a half. Here are the instructions I used.
http://autorepair.about.com/od/regularmaintenance/ss/coolant_flush.htm Hopefully this helps. E-mail me at raspyjaspy@hotmail.com and tell me if this worked for you as it did for me!

Sounds like the flap valve in your vent system that allows air to go to the defrosters is either jammed or broken. Unfortunately you will have to take the vent system apart to look.
