Rats - OK, we'll see where things go from here. Foamy, if the air flow seems low, try removing the cabin air filter and see if it improves.

Yes the air flow is good but just warm and I have flushed the whole system. I forgot to do the heater core when I did a full system flush. The coolant level is full and the cap is all the way on. Are there any other actuators that I'm missing. Not sure what to do about this darn thing. The only thing I could think would be to check the pressure on the coolant system. Do you think that if there was not enough that would make a difference?

This is a link to the actuators. HVAC System - Automatic If you aren't building pressure, perhaps you have a bad cap. I doubt that would affect your heat, however.

Default no heat also

Not hi-jacking the thread, but Imm having this same problem also, 2000 Bonnie SLE w/45000. miles on the clock. Everything runs fine, all gauges in the normal operating range, plenty of air flow, but no heat. The dealer wants to replace the upper and lower intake manifolds, gaskets, water pump and do a coolant flush. I ask what did that have to do with no heat and got the deer in the headlights look, like why am I asking that question.

Your friend has already checked the actuators?

Okay now shes saying it comes out hot, but the drivers side doesnt blow very hard at all, especially on the floor.

I will try to get her to make a Screen name..

Check out the link that I posted about 6 up. It gives information on all of the actuators, and should at least give you a place to start. I've always thought that the air flow to the floor on the drivers side was rather sad. You can also check to see if the hush panel, that doubles as a plenum, is installed properly. The techinfo article on the intermediate steering shaft should help you there.
