Question about 2000 Ford Taurus
This is because you have a vacuum leak. It defaults to defrost by law. You need to check a few things under the hood.
1. check the vacuum line that runs from the engine to and through the firewall into the passenger compartment for a leak. It is usually about 1/8 inch black plastic line.
2. check for a vacuum leak in the line going to the storage canister (Plastic ball) that stores vacuum for when you go up hills.
3. check for a leak in the canister.
4. check to e sure the check valve is not bad. It prevents vacuum loss when you shut car off.
