A/C Service for GMC Sierra 2500

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Your steering wheel feels like it's burning your hands. Sweat soaks the driver's seat. You wipe your brow and wonder, "Who can fix the A/C in my GMC Sierra 2500?" Firestone Complete Auto Care can! We know GMC vehicles, and our technicians are qualified to diagnose and repair 1999 GMC Sierra 2500 A/C systems. Bring your GMC Sierra 2500 to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 1999 GMC Sierra 2500 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 2500 A/C system to detect refrigerant fumes escaping from the system. If your system has a leak, we can get it fixed.

Recharge the A/C in Your Sierra 2500

When we perform an A/C repair on your 1999 GMC Sierra 2500, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll use GMC’s specifications to evacuate the system. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you’re all set. Our technicians are trained to efficiently perform 1999 GMC Sierra 2500 A/C recharges.

Troubleshooting GMC Sierra 2500 A/C Problems

Hot air is a common GMC Sierra 2500 A/C problem, but it’s not the only issue you might encounter. Other common A/C problems include weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. And smelly A/C in a 1999 GMC Sierra 2500? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. Our trained technicians will do what they can to solve your A/C problems. So, chill out. We're here to help you get the blast back in your Sierra 2500’s A/C!

Frequently Asked Questions for 1999 GMC Sierra 2500 A/C Systems

  • Can I make my Sierra 2500 air conditioner 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.
  • Why is my Sierra 2500 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.
  • How does my A/C system get a leak? To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your Sierra 2500’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Is my Sierra 2500 A/C powered by gas? Sierra 2500 air conditioning systems don’t use gasoline as a direct fuel source. However, they do rely on engine power, which can indirectly affect your vehicle’s gas mileage.
  • What does it mean if the A/C in my Sierra 2500 smells like vinegar? Moisture can accumulate on your vehicle’s A/C system components, creating the perfect breeding ground for bacteria. As this bacteria grows, it can cause the air conditioning system in your Sierra 2500 to have a vinegar-like smell.
  • Why does my vehicle have to be moving for my Sierra 2500’s A/C to work? Damaged or worn components in your Sierra 2500’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.
  • Where can I get my Sierra 2500’s A/C repaired? Firestone Complete Auto Care is ready to inspect and repair your Sierra 2500’s air conditioning system. Make an appointment at one of our nearby A/C repair shops today.
