there si a valve attached to the one heater line against the firewall, is the valve moving when you move the temp slesctor on and off? you said the blower is workign but nothing coming out? do you mean no hot air or no air at all? the cage on the blower motor is made of thin plastic and is known to disintigrate

If the temp is rising but you're not getting any heat, my guess would be is that you didn't burp the system. You'll have to get the air out of it. Let the car run w/o the air on and let it warm up w/o the radiator cap off and let the air burp out. Probably take 10-15 mins depending upon how much air is in it. You can also purchase a spill-free funnel that would adapt to the radiator cap and you could use that to flush it with.

Good luck with the solving the problem.
