Please check notes in each part listing to ensure the Blower Switch is correct for your 1991 FORD MUSTANG with a 5.0L engine. STANDARD MOTOR PRODUCTS, AIRTEX / WELLS, FOUR SEASONS, & MOTORCRAFT are competing brands, and each brand's Blower Switch may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Blower Switch fits only certain 1991 FORD MUSTANG models.
Clicking a "More Info" link will display a picture and/or other details about that Blower Switch in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Blower Switch, 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 Electrical-Switch & Relay parts, other FORD MUSTANG 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 1991 FORD will not be lost if you switch.
