Please check notes in each part listing to ensure the Defogger Relay is correct for your 1998 CHEVROLET BLAZER with a 4.3L 262 engine. Special restrictions like "California only" or "with sport package" may indicate a Defogger Relay fits only certain 1998 CHEVROLET BLAZER models.

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

After choosing a Defogger 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 on "Find More Parts", to find more Electrical-Switch & Relay parts, other CHEVROLET BLAZER parts, or parts for a different vehicle. Please try our Interactive Catalog (click red Start button above) for faster searching.
