Please check notes in each part listing to ensure the Dimmer Switch is correct for your 1980 PONTIAC CATALINA with a 5.7L 350 DIESEL engine. AIRTEX, STANDARD MOTOR PRODUCTS, & ACDELCO are competing brands, and each brand's Dimmer Switch may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a Dimmer Switch fits only certain 1980 PONTIAC CATALINA models.

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

After choosing a Dimmer 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 PONTIAC CATALINA 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 1980 PONTIAC will not be lost if you switch.
