Heat isn't blowing hot 2007 dodge nitro
Ive replaced the water pump, thermostat,
heatercore, hvac box, blower motor, radiator and
cap. Topped off on fluid, burped the system and
get good heat but after just a few minutes it's
gone. When i leave the blower off for long enough
when driving i can turn it on and have heat for
about 5 seconds. Im at a lose here, any
suggestions? Its November in wisconsin, having
heat is a must.
