Heater won't get hot.

Heater won't get hot.
99 LT model.
I have replaced some bad vaccume lines I found
that were bad. The system works on all the settings,
floor defrost etc. A/C blows cold, etc.
I am not convinced that I don't have a vaccume leak
somewhere. Doesn't seem like the flapper door that
moves to heat is working.
I was wondering if anyone has come across this problem in
the past and if there was a cure. Thanks in advance, Al.

Heat fixed.
So here's the scoop on this one.
I followed the directions from the link posted rockp2. Everthing seemed to be working as it should.
OK, what's next... Warthogdriver says it could be stopped up, hmm...
Removed the lines to the heater core and the large 3/4 line seemed dry. DO NOT use compressed air, lol. If you do, you will be blind for a few moments hunting fresh water.
Took the water hose and fushed one to the other, back and forth 6 or 8 times and replaced the lines. It worked! I didn't see a bunch of crud or calcium deposits come out, but I think there might have been an air bubble causing it to vapor lock possibly? It is blowing hot now.
Thanks for all the great advice guys, Al.
