Please check notes in each part listing to ensure the Heater Blend Door Actuator is correct for your 2009 MERCURY MARINER with a 3.0L engine. DORMAN & STANDARD MOTOR PRODUCTS are competing brands, and each brand's Heater Blend Door Actuator may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Heater Blend Door Actuator fits only certain 2009 MERCURY MARINER models.

Clicking a "More Info" link will display a picture and/or other details about that Heater Blend Door Actuator in a separate window (you may need to turn off your pop-up-blocking software for this to work).

After choosing a Heater Blend Door Actuator, click the "Add Part" button. Shipping costs will be shown on the Shopping Cart page. You may use your browser's Back button or click "Find More Parts" to find more Heat & Air Conditioning parts, other MERCURY MARINER parts or parts for a different vehicle. Please try our Interactive Catalog (click link above) for faster searching. Both catalogs use the same shopping cart so any auto parts you've already chosen for your 2009 MERCURY will not be lost if you switch.
