Question about 2004 Mercury Sable
You may have two problems here. The idle air controller (I.A.C.) has nothing at all to do with the vehicle's air conditioner. If the A/C is not working, I would look at the compressor to see if it is working. The compressor clutch could be causing an idle problem if the bearing is going bad. A quick test would be to remove the serpentine belt and see if the car idles fine. Do not run the engine this way for more than 30-60 seconds because the water pump will not be turning without the belt in place.

Its not a motor, its an Idle Air Control valve.
