Start by checking the A/C fuse and relay. Ensure the refrigerant level is adequate. Inspect the compressor clutch and electrical connections. If the problem persists, consult a professional mechanic.
Regular maintenance includes oil changes every 3,000-5,000 miles, tire rotations every 7,500 miles, and a comprehensive check-up every 15,000 miles. Refer to the owner’s manual for a detailed schedule.

To improve fuel efficiency, ensure regular maintenance, keep tires inflated to the correct pressure, reduce excess weight, and drive smoothly avoiding rapid acceleration.
Check the transmission fluid level and quality. If it's low or burnt, it may need to be topped off or changed. Persistent issues should be examined by a professional mechanic.
Enable Bluetooth on your phone. On the Sierra's infotainment system, select the "Phone" or "Bluetooth" menu, then "Pair Device." Follow the prompts to complete pairing.
