Best Answer

The Grand Marquis uses the same HVAC system as the Ford Taurus and Mercury

Sable and all three automobiles suffer from the same blend door failures. The actuator is located on the front side of the plenum box and you can see it if you fully open the glove box and look to the left over the transmission tunnel. The recommended dealer fix is to remove the dash and plenum box and replace the plastic door. There is a kit on Ebay from HeaterTreater that offers a cheap easier fix for this problem.
