No heat

[deantheking]

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.

Does your car have an EATC, if so perform the self diagnostic.

Check your blend door as well.

It does not have a EATC. And do you know if i can just pull the ash trey out and see if it is moving?

You'll have to drop the glove compartment and/or pop the radio/climate oval off to see it. Make sure the shaft rotates 90º from cold to hot.

Don't replace the thermostat unless you measure the temps and see that the coolant temp is too cold. You risk breaking studs on the thermostat housing. Heater hoses should both be quite hot (difficult to hold) when everything is operating properly.

Dean, if your manual blend door actuator has never been changed, it'll probably be white.
