How do I make my Sierra 3500 HD air conditioning colder?

Park in the shade whenever you can, and use a reflective sunshade in the windshield when you’re parked. If you’re the only one in the car, close all the vents except the ones that point toward you. Give the system the final boost it needs with an A/C performance check and recharge from Firestone Complete Auto Care.

What’s making my Sierra 3500 HD A/C put out warm air?

Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.

How does my A/C system get a leak?

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 3500 HD's A/C system.

Does my Sierra 3500 HD A/C run on gas?

Your Sierra 3500 HD’s A/C uses some power from the engine to run. So, while your air conditioning system may not directly use gasoline as a fuel source, using the A/C can indirectly affect your vehicle’s fuel efficiency.

My Sierra 3500 HD’s A/C smells like vinegar! What can cause that?

It’s easy for moisture to accumulate in your car’s air conditioning system, which can cause microorganisms like bacteria to grow. In turn, this bacteria growth can cause the A/C in your Sierra 3500 HD to produce a vinegary odor.

Why does my Sierra 3500 HD’s A/C only work when the car is moving?

If your A/C only works when the vehicle is moving, there could be a problem with part of your Sierra 3500 HD’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

GMC Sierra 3500 HD A/C Repair

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. Your skin sticks to the driver’s seat. You take a deep breath and ask yourself, “Who can fix my GMC Sierra 3500 HD A/C?” Easy — Firestone Complete Auto Care! We know our way around GMC vehicles, and our trained technicians can identify and repair issues with 2010 GMC A/C systems. Steer your GMC Sierra 3500 HD to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 2010 GMC Sierra 3500 HD A/C system to evaluate what repairs are necessary (if any). We’ll test overall system performance, check for any leaks, and measure the system pressure. If we think there might be a leak, we'll run a special U/V dye through the system or use a "sniffer." A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your GMC Sierra 3500 HD A/C system to detect any refrigerant fumes that might be leaking out from the system. If your A/C system has a leak, we’ll find and repair it.

Recharge the A/C in Your Sierra 3500 HD

While your 2010 GMC Sierra 3500 HD’s air conditioner is being serviced, 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. To finish, we’ll add new refrigerant to recharge the A/C system, and once we’ve done a final test on the system ourselves, you’re good to go. We want you to be comfortable in your car, so we train our technicians to perform 2010 GMC Sierra 3500 HD A/C recharges.

Troubleshooting GMC Sierra 3500 HD A/C Problems

You may think warm air is the only potential GMC Sierra 3500 HD 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. An A/C system that starts off blowing cold air but then turns warm 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 2010 GMC Sierra 3500 HD? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our trained technicians will do what they can to solve your A/C problems. Don’t sweat it — we’re here to help you chill out again in your Sierra 3500 HD.
