2000 Buick Le Sabre

The temperature control for the heater isn't working properly. There is little or no heat until the controller is nearly at maximum setting; so it is either too hot or too cold.

What is the fix for this problem?

Digital or manual control?

either way, I'd say climate control assy replacement. They are not that expensive and were easy to swap out. Does the coolant reach normal temperature?

It is manual control and the engine temp is normal. Also when the temp lever is at max temp the air flow throttles back, and when the temp lever is moved to lower temp the air flow increased...all with no change in the fan setting.

If I change out the climate control where is it located?

well, it's located exactly where the manual adjustments are. normally, it's a rectangular box right behind the bazel that covers controls. normally, it's clipped on. might be some hidden bolts securing it in place.
they used to be around $60+ new from a store.
That air flow speed changes is basically telling that blender doors do operate, at least, to some extent, as at max heat, air has to go through heater core more than it goes through it when set to cold. heater core is restraining air flow somewhat being basically a radiator.
if it's a manual manual climate control, you very likely to have simple levers and rods operating gears that operate blender doors. those do sometimes brake or come off.
honest suggestion - go to a library and copy pages from Chilton on how to do it.
