check the heater control valve. that is what controls the heater part of your system.

If the **** points to 1 or 2 and in the redfor heat and on the right hand side of middle **** over to the white and blowing out top it is very hot so i assume leave it on those when heat is needed???

The valve under the hood that allows coolant to flow to the heater core???? Don't think '00 models have that, '98s don't.

if you have a vaccume leak then the heater goes to the default position and works in defrost mode only. Sounds like vac leake to me.
