Listen, I have an '86 Buick Park Ave. The heat doesn't work. Heres what I have going on:
1 the fan blower works
2 I replaced the thermostat
3 I flushed the radiator and filled w/ new antifreeze
4 I dont smell antifreeze in the car
5 my front passenger carpet isn't wet


What could it be?

have you looked at this?

if its a control box you should be able to replace this easy with a junk yard fix. Also look for any stuck doors or loose or stiff cables. if the A/C will blow cold air then look for you temp control door stuck.

The only other thing I could think is if the heater core is so pluged that you need to replace it. They don't always leak when they go bad.
