My car is a 2002 Mercury Sable GS, The past year every time I turn my heat on all that blows out is cold air. I have had a coolant flush, change the thermostat and the heating core and yet all it does is still blow out cold air when I turn the heat on. Why?

I think you have a problem with your blend door. A blend door swicthes or (flip) from side to side in your ac and heating system. Distributing either hot or cold air. Sometime it's the blend door or the vaccum that operate it.(under dashborad) THE PHANTOM

My 2000 does the same thing. Where do I look to check the condition of the vacume lines; under hood? under dash? If under dash what location specifically.
