Are your brake lights staying on, not working at all, or maybe your cruise control has stopped working? On many 2007-2011 GM trucks and SUVs, a faulty brake light switch is a common cause. This replacement switch fits Chevrolet Avalanche, Tahoe, Silverado 1500/2500HD, and the GMC Sierra 1500 from those years. It replaces OEM part numbers like SLS450, SW8252, and S41149. It's a small, inexpensive part that plays a big role in safety and convenience. Installation is usually pretty simple and located up under the dash near the brake pedal. Always double-check your vehicle's specific year and model. Fixing this can resolve your brake light issues and often get your cruise control working again. A quick, easy repair to ensure you're driving safely and legally.
