Please check notes in each part listing to ensure the A/C and Heater Control Switch is correct for your 1988 GMC V1500 SUBURBAN with a 5.7L 350 engine. ACDELCO & FOUR SEASONS are competing brands, and each brand's A/C and Heater Control Switch may be interchangeable. Special restrictions like "California only" or "with sport package" may indicate a A/C and Heater Control Switch fits only certain 1988 GMC V1500 SUBURBAN models.

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

After choosing a A/C and Heater Control 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 GMC V1500 SUBURBAN 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 1988 GMC will not be lost if you switch.
