Buy a repair manual and check the procedure to see if you want to attempt it yourself. If you've never pulled a dash apart, be prepared for some cursing and steaming- it aint fun! If you do it, make notes as you go along, and keep screws and everything taken off or out in an orderly way. Note where every electrical connection came apart. It CAN be done, just depending on how much you want to save 600 dollars. No special tools are required, just an ordinary set of hand tools and sockets, maybe a steering wheel puller. I've done it a few times-and found I never made enough notes to self.

No, not really. Even if you could hack your way to it's approximate location, there's way too much involved with no room to do anything for you to have any success. You can't just say "okay, there it is" because you can see it, and fix it

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.

I have been told that it costs approx $600.00 to fix my 2003 mercury actuator blend door and that you have to remove the dash to fix is there another way like diy?


No there isn't a way to get at it other then removing the dash. As far as the cose it depends on the shop and its hourly labor rate. The part should cost at the most $100 and if you have the automatic temp control system it list for 5.2 hours of labor. If you just have the regular system it should be 4 hours of labor so if you can find a good shop at a lower labor rate you may want to go with them. Just a suggestion and that is cheaper is not always better but if you can find a good shop with a lower labor rate that should help with the total cost but make sure the shop has a good reputation.

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.

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.

Hot air comes out the passenger side when air condirioning is on.


The control module or actuator is most likely the cause. You can manually set it for cold air until winter. Actuator is under the dash right by the blower.

most likely needs a LH (bottom) temp actuator. Located in the center of the dash on the bottom, you have to remove the hush panel on the rh side of the truck
