I have a 02 Taurus 3.0with no heat and 80k on it. I bought it with 75k and it did not work when i got it. Now that it is getting freezing her in LA ;-) i would like the heat to work. When the car is warmed up and still parked when you turn the heat on it comes out warm for 30 seconds then starts to get cold again. I dont hear any thunk or clicking when i change the dial from hot to cold dont know if i should or not. I just flushed the cooling system and that did not help but it needed it either way. The hoses coming into and out of the heater core are both hot. I have the day off tomorrow and was planning on replacing the thermostat. Any other ideas?
Thanks for looking.
