I have had it with this car. I did another full flush since I still had dex coming out. Still no heat. I decided to flush just the heater core and it still seemed plugged. What I decided to do was get some 3/4 clear hose and install so I could see exactly what was going on. The hose is only rated to 175 F but it had no problem. I did notice there was hardly any flow going to the heater core and even less coming out. I flushed the heater core again by filling up the inlet and I made a fitting to use compressed air and got a lot of crap out and now it seems to flow a little better but still no heat. I still feel that when watching the inlet there is never full pressure on the heater core and a ton of air just sitting there. On the outlet coolant is coming out but very slow. Just wondering if the pump should be trying to push it faster or if it is still plugged up. I think I'm just going to have to break down and replace the heater core (no fun).

With all that you have tried...it seems that it is plugged and your best fix would be to replace it.

I fixed it and now have heat. It was a plugged heater core. I was getting ready to buy another one and dive into installing it when I decided to give it one last chance. I hate dex cool and that crap should be outlawed.

Any idea if the car sat idle for periods of time?

The car has not sat idle for long periods of time that I know of. I really think it was the break down of dexcool and the fact that the car has 130,000 miles on it and this is the first full system flush. I know shame on me... I learned my lesson.
