Air lock has me stumped

Hello All.
Did a little preventative maintanance today and now I am stumped. Flushed the radiator and changed the antifreeze. Now I think I have a air lock in the heater. The heater will get up to maybe half of what it should be when driving but when it goes back to lower rpms it blows cool air again. Have let it idle for about a half hour with the fan on, driven it uphill, down hill, reved it up,Doesnt seem to change. The heater hoses are fairly warm but not as hot as i think they should be.The radiator is clean. I have run into this before but never taken this long to get it right. Yes the heat was fine before the fluid change and its a 50 50 mix with prestone . Any ideas.


Thanks Bones
