My 04 pacicfica heating goes hot and cold i need help
the heater blows great front back and out of all vents, fuses are good, the air will blow
cold for quite awhile after the engine is at operating temp, then it will get warm for a few
mins but then return to cold outside air temp again. Is this a thermostat issue or have i
got bigger problems on my hands? Thanks for any help guys and gals!
