A/C Service for GMC Sierra 1500

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like lava. Sweat soaks the driver's seat. You wipe your brow and wonder, "Who can fix the A/C in my GMC Sierra 1500?" Easy — Firestone Complete Auto Care! We know GMC vehicles, and our trained technicians can identify and repair issues with 1999 GMC A/C systems. Bring your GMC Sierra 1500 to your local Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1999 GMC Sierra 1500’s A/C system to determine whether repair work is needed. We’ll test overall system performance, check for any leaks, and measure the system pressure. 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.” A "sniffer" is a machine that's run along parts of your GMC Sierra 1500 A/C system that can identify points where refrigerant fumes could be escaping the system. If your A/C system has a leak, we’ll find and repair it.

Sierra 1500 A/C Recharge

When we perform an A/C repair on your 1999 GMC Sierra 1500, 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. Next, they will evacuate the system according to GMC's recommendations. To finish, we’ll add new refrigerant to recharge the A/C system, and once the technician tests the cool blast for themselves, you’re good to go. Our technicians are trained to efficiently perform 1999 GMC Sierra 1500 A/C recharges.

Other GMC Sierra 1500 A/C Problems

Hot air is a common GMC Sierra 1500 A/C problem, but it’s not the only issue you might encounter. Another common A/C problem is 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. Are you breathing in some “interesting” new odors in your 1999 GMC Sierra 1500? 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. So, chill out. We're here to help you get the blast back in your Sierra 1500’s A/C!

Questions About 1999 GMC Sierra 1500 A/C Systems

  • 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 do I get hot air from my Sierra 1500 A/C? 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.
  • How does my A/C system get a leak? 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? 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 does it mean if the A/C in my Sierra 1500 smells 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.
  • Why does my Sierra 1500’s A/C only work when the car is moving? 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.
