Please check notes in each part listing to ensure the Interior Light Relay is correct for your 1999 PONTIAC GRAND PRIX with a 3.8L OHV engine. Special restrictions like "California only" or "with sport package" may indicate a Interior Light Relay fits only certain 1999 PONTIAC GRAND PRIX models.
Clicking a "More Info" link will display a picture and/or other details about that Interior Light Relay in a separate window (you may need to turn off your pop-up-blocking software for this to work).
After choosing a Interior Light Relay, 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 GRAND PRIX 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 1999 PONTIAC will not be lost if you switch.
