How to Reset Blend Door Actuator on a Grand Marquis

The blend door actuator is a small motor that controls the temperature of the air coming out of your car’s vents. If this actuator goes bad, it can cause your car to blow hot or cold air even when you’ve set the temperature to something else. Fortunately, resetting the blend door actuator is a relatively simple task that you can do yourself.

In this article, we’ll walk you through the steps of resetting the blend door actuator on a Grand Marquis. We’ll also provide some tips on troubleshooting common problems with the blend door actuator. So if your Grand Marquis is blowing hot or cold air, read on to learn how to fix it!

The blend door actuator is a motor that controls the temperature of the air coming out of your car’s vents. It’s located in the dashboard, and it’s responsible for moving the blend door, which is a flap that directs air to the heater core, the evaporator, or both. When you change the temperature setting on your car’s climate control system, the blend door actuator moves the blend door to the appropriate position, allowing the correct amount of hot or cold air to enter the cabin.

If the blend door actuator fails, it can cause a number of problems, including:

• The air coming out of the vents may be too hot or too cold.
• The air may not be blowing out of all of the vents.
• The temperature of the air may fluctuate.

If you’re experiencing any of these problems, it’s possible that the blend door actuator is to blame. In this article, we’ll show you how to identify, test, and replace the blend door actuator in a Ford Grand Marquis.

Identifying the Blend Door Actuator

The blend door actuator is a small, cylindrical motor that’s located in the dashboard, near the heater core. It’s usually connected to the blend door by a linkage.

To identify the blend door actuator, follow these steps:

1. Locate the heater core. The heater core is a large, metal block that’s located in the dashboard, behind the glove box.
2. Look for a small, cylindrical motor near the heater core. This is the blend door actuator.
3. Trace the linkage from the blend door actuator to the blend door. The linkage is a series of rods and cables that connect the blend door actuator to the blend door.

Where is the blend door actuator located?

The blend door actuator is located in the dashboard, near the heater core. It’s usually connected to the blend door by a linkage.

How to access the blend door actuator?

To access the blend door actuator, you’ll need to remove the following parts:

• The glove box
• The heater core cover
• The blend door

1. Removing the glove box

1. Open the glove box.
2. Locate the two screws that hold the glove box in place.
3. Remove the screws.
4. Carefully lift up the glove box and set it aside.

2. Removing the heater core cover

1. Locate the heater core cover. It’s a metal plate that’s located behind the glove box.
2. Remove the screws that hold the heater core cover in place.
3. Carefully lift up the heater core cover and set it aside.

3. Removing the blend door

1. Locate the blend door. It’s a flap that’s located in the air duct, behind the heater core cover.
2. Remove the screws that hold the blend door in place.
3. Carefully lift up the blend door and set it aside.

Testing the Blend Door Actuator

There are two ways to test the blend door actuator:

• With a multimeter
• With a scan tool

Testing the blend door actuator with a multimeter

1. Disconnect the negative battery terminal.
2. Locate the blend door actuator connector. It’s a black connector with four wires.
3. Connect the red multimeter lead to the positive battery terminal.
4. Connect the black multimeter lead to the brown wire on the blend door actuator connector.
5. Turn on the multimeter.
6. Set the multimeter to DC voltage.
7. Move the blend door actuator switch to the “On” position.
8. The multimeter should read between 10 and 12 volts.
9. Move the blend door actuator switch to the “Off” position.
10. The multimeter should read 0 volts.

If the multimeter reads 0 volts in either position, the blend door actuator is bad and needs to be replaced.

Testing the blend door actuator with a scan tool

1. Connect the scan tool to the OBD-II port.
2. Turn on the scan tool.
3. Select “Actuator Test” from the menu.
4. Select “Blend Door Actuator” from the list of actuators.
5. The scan tool will command the blend door actuator to move to the “On” position.
6. The blend door should move.
7. The scan tool will command the blend door actuator to move to the “Off” position.
8. The blend door should move.

If the blend door does not move, the blend door actuator is bad and needs to be replaced.
