GMC C3500 A/C Repair

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Is that a hot stove? Nope, just your steering wheel. Your skin sticks to the driver’s seat. You wipe your brow and wonder, "Who can fix the A/C in my GMC C3500?" Firestone Complete Auto Care can! We’ve got experience with GMC vehicles, and our technicians are qualified to diagnose and repair 1986 GMC C3500 A/C systems. Bring your GMC C3500 to your local Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 1986 GMC C3500 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 we suspect a leak, we’ll send a U/V dye through your A/C system or use a “sniffer” to find the leak. What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your GMC C3500 A/C system to detect any refrigerant fumes that might be leaking out from the system. If your system has a leak, we can get it fixed.

Recharge the A/C in Your C3500

When we perform an A/C repair on your 1986 GMC C3500, 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. Next, they will evacuate the system according to GMC's recommendations. The A/C system is recharged with new refrigerant and once we’ve done a final test on the system ourselves, you’re all set. We want you to be comfortable in your car, so we train our technicians to perform 1986 GMC C3500 A/C recharges.

Troubleshooting GMC C3500 A/C Problems

Hot air is a common GMC C3500 A/C problem, but it’s not the only issue you might encounter. Another common A/C problem is weak airflow, which could mean you have a compromised seal, mildew or mold buildup, a loose or damaged hose, or a ventilation fan that needs to be replaced. If your A/C system blows cold air first but then it turns warm, this may suggest a leak, a blown fuse, or a damaged compressor clutch. And smelly A/C in a 1986 GMC C3500? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. 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 C3500.

1986 GMC C3500 A/C System FAQs

  • How do I make my C3500 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.
  • What’s making my C3500 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 C3500's A/C system.
