How do I make my Sierra 1500 air conditioning colder?

For starters, use a sun-blocking shade in the windshield while you’re parked, or look for a shady parking spot. Closing all the passenger vents in your car can help redirect cold air toward you, cooling you off faster. Still need more chill? Head to Firestone Complete Auto Care for an A/C performance check and recharge.

Why is my Sierra 1500 A/C blowing hot air?

If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.

What causes A/C system leaks?

A/C system leaks are often due to a combination of age and moisture. Rubber seals and gaskets naturally degrade over time, allowing refrigerant to exit and moisture to enter your Sierra 1500's A/C system.

Is my Sierra 1500 A/C powered by gas?

While your vehicle’s A/C system doesn’t directly use fuel, it does draw power from the engine, which can impact the fuel consumption of your Sierra 1500.

What can cause the A/C in my Sierra 1500 to smell like vinegar?

If the air conditioning in your Sierra 1500 smells like vinegar, it could be due to bacteria growth on system components such as the evaporator and heater cores. Bacteria can grow when moisture accumulates on air conditioning system components, providing a breeding ground for microorganisms.

What is causing my Sierra 1500’s A/C to only work when the car is in motion?

Damaged or worn components in your Sierra 1500’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

During an A/C performance check, we'll determine the condition of your 2020 GMC Sierra 1500 A/C system to evaluate what repairs are necessary (if any). This check includes a visual inspection, performance test, and pressure and leak test. If any signs point to a possible leak, we’ll send a special U/V dye through the system, or use something called a “sniffer.” What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your GMC Sierra 1500 A/C system to detect any refrigerant fumes that might be leaking out from the system. If there's a leak, we'll find it and fix it.

Next, they will evacuate the system according to GMC's recommendations. Finally, we’ll recharge the A/C system with new refrigerant and once we’ve done a final test on the system ourselves, you're ready to get back on the road. Our technicians know how to keep your A/C in tip-top shape with 2020 GMC Sierra 1500 A/C recharges.

Common GMC Sierra 1500 A/C Problems

Warm air isn't the only GMC Sierra 1500 A/C problem you may encounter. Other common A/C problems include weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this may be due to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2020 GMC Sierra 1500? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. Don’t sweat it — we’re here to help you chill out again in your Sierra 1500.
