How can I make my Sierra 1500 air conditioner 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?

An A/C blowing hot air has several possible root causes. There could be an issue with your compressor clutch, a blown fuse, a leak, or a clog in the expansion valve.

What causes A/C system leaks?

Over the years, the rubber seals and gaskets in your Sierra 1500’s A/C system naturally degrade. Moisture can get into the system and cause a malfunction, or parts can simply wear out so that your system no longer seals properly.

Does running the A/C in my Sierra 1500 use gasoline?

The air conditioning system in your Sierra 1500 does not use gasoline directly as a fuel source, but it does require some power from the engine, which indirectly affects your car's fuel consumption.

What does it mean if the A/C in my Sierra 1500 smells like vinegar?

If a vinegar-like odor comes from your A/C, bacteria growth could be the culprit. Moisture accumulation in the air conditioning system of your Sierra 1500 creates a breeding environment for microorganisms.

Why does my vehicle have to be moving for my Sierra 1500’s A/C to work?

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.

A/C Service for GMC Sierra 1500

Few things are worse than a broken car air conditioner on a hot summer day. Is that a hot stove? Nope, just your steering wheel. That puddle in the driver’s seat? Sweat. Ugh. You take a deep breath and ask yourself, “Who can fix my GMC Sierra 1500 A/C?” Firestone Complete Auto Care — that’s who! We’ve got experience with GMC vehicles, and our trained technicians can identify and repair issues with 2019 GMC A/C systems. Bring your GMC Sierra 1500 to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2019 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 we suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your GMC Sierra 1500 A/C system to detect refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

Sierra 1500 A/C Recharge

When we perform an A/C repair on your 2019 GMC Sierra 1500, we’ll also do an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. Then, they’ll use GMC’s specifications to evacuate the system. Finally, we’ll recharge the A/C system with new refrigerant and after one final test to be sure the system is cooling properly, you’re all set. We want you to be comfortable in your car, so we train our technicians to perform 2019 GMC Sierra 1500 A/C recharges.

Common GMC Sierra 1500 A/C Problems

You may think warm air is the only potential GMC Sierra 1500 A/C problem you’ll have, but you may notice other issues, too. 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 suggest a leak, a blown fuse, or a damaged compressor clutch. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2019 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. We’re here to help you get back on the road in your Sierra 1500 — without all the sweat puddles!
