Please check notes in each part listing to ensure the Heater Blend Door is correct for your 2004 DODGE RAM 2500 PICKUP with a 5.9L DIESEL Turbocharged engine. DORMAN & GPD are competing brands, and each brand's Heater Blend Door may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Heater Blend Door fits only certain 2004 DODGE RAM 2500 PICKUP models.
Clicking a "More Info" link will display a picture and/or other details about that Heater Blend Door 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, 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 DODGE RAM 2500 PICKUP 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 2004 DODGE will not be lost if you switch.
