check to see if both hoses are hot going to your heater core if they are then core is fine.That would point to your temperature sensor.

SOURCE: 2000 buick lesabre no heat.

The heat is generated by a heater/small radiator in the dash. That small radiator uses hot coolant from the engine. The temperature is adjusted by varying the amount of hot water flowing thru it with a valve. That valve is commanded by a lever to which a cable coming from the temperature button is fixed - this mechanism no longer works causing the valve to remain shut so you end up with no heat.
You must access the back of the rear console to inspect and replace the failed part: the button, the cable, the lever or the valve itself. Of course you must do that with the engine cold.
The entire procedure is explained in detail - with pictures and diagrams - in this repair manual
