2000 ford taurus. FIrst off this is my first post. I think its cool that theres a forum for the tortoise. Anywho. Im tired of freezing in the mornings on the way to work. My heat does not blow hot at all. It blows freexing cold air when its cold outside and regular ambient temp air when its warm out. Ive read up on flushing the heater core, im gonna attempt it this weekend. WHat kind of time should i expect it to take? Also, ive read about a blend door possibly not working, will i hear a noise of some sort when attempting to turn on the heater now if it is working? HOw can i check it to eliminate it from the equation. Thanks so much. Feel free to give advise or comments. Have a great morning.
