The heater core on a Dodge Dakota is inside the HVAC housing, under the dash.
dodge Dakota 1993 looses power pulling trailer up hills, whats wrong?
Could also be a short to ground. If it runs all the time that's what it probably is. Get a wiring diagram and figure it out

This is my son-in-laws truck. I have to fix it

Lots of things.But probably a clogged heater core.

It is located behind the passenger side dashboard. The dashboard has to be removed to replace.
I wouldn't think you could flush a heater core. you can flush a radiator. Heater core you would have to replace if it is leaking or stopped up
