I have checked every site that I can think of and run the question many times, unable to get the procedure, maybe a nice tech at the local dealer will help u out, if not I guess buying a service manual might be your only option. I am a retired Ford mechanic, I did almost all the AC work, I never found this problem was a control head issue, it was always the blend door electric motor, I think you can see it from the glove box if you remove the liner.

SOURCE: Mercury grand marquis 1997 temperature control

I'm not sure if yours is identical to mine since yours is second gen and mine is third gen, but with mine (1998 MGM), the heat was stuck on all the time. Full heat would practically cook your feet and you couldn't shut it off.

It was a servo/servo arm that controls the hot/cold mix door. The part was $15. The labor was $700. They had to take the entire dash out of the car to get at the part. Required two more visits due to a missed electrical connection to a daylight sensor and a vacuum issue that made the car stall when put into reverse.

My car had 150K on it at the time. Has 165K on it now. Still runs great and looks great. It's now my wife's auto and I drive a 2006 MGM.

NO HEAT STUCK ON AC HEAR CLICKING IN CENTER CONSOLE


Air Temperature Control Blend Door Failure No Heat or no AC (dependes on where door sticks)

In all modern cars there is a tiny DC electric motor driven gear drive that moves a plastic door that blends heated and cooled air from the AC and the heater core, this is called (interestedly enough) the air temperature control blend door actuator. The motor that moves this door fails because the door starts sticking from warping, most common complaint is no heat but it can be no AC as well. To replace these parts (blend door and blend door actuator) you must remove the entire dash from the car. Always have this problem confirmed by a dealer or qualified repair shop as it is a very expensive repair.

Other causes of no heat in the cabin are engine thermostats that are stuck open (engine runs cold) or air bubbles in the cooling system.

Heater blows cold air


Hi!
If the Temp. Selector Control is set to Heat and blows cold air, your Blend Door Actuator may be stuck or it is inoperative. The actuator is not fixable, if it fails, it must be replaced. Follow the instructions to remove and replace it.
  1. Disconnect battery negative cable from battery and properly isolate to prevent accidental reconnection.
  2. Remove the instrument panel.
  3. Disconnect the electrical connector from the blend door motor/actuator.
  4. Remove the four screws holding the blend door actuator to the plenum.
  5. Remove the temperature blend door actuator.

How do I remove the dash to replace blend door actuator

2003 mercury grand marquis LS heater does notr blow hot air, blower blows but cold air comes what is the problem


The blend door is stuck in cold position. That usually happens because the blend door actuator has failed.

You will need to test and replace the blend door actuator.

To replace the actuator you will need to take apart the dash and remove completely the instrument panel,d isconnect the connector, remove the four screws, remove the temperature blend door actuator and replace it.

The replacement is not a job for beginners, since you have to take apart the dash to access the actuator.

Regards.
