Inside the dash, in the HVAC housing. The entire dash has to be removed to access.
the heater core is bad
Heater core is on the passenger side behind the glove box, this is also the location of the air conditioner evaporator core.. they should be in the same housing.
Probably the evaporator core has mould on it and needs to be cleaned.

Heater Core is the likely culprit
I have looked up time to change heater core on 2000 dodge caravan it said 2 hours. I have never done this so I need to know where to start?
it's right behind the front bumper. in front of the engine. there is no radiator cap on it. only the heater core is on the radiator.
You need to recover the R134 charge, remove the whole dashboard, then remove the a/c heater box to get to the heater core. The heater core should be accessible right next to the gas pedal. No dash removal is necessary.
