How do I make my SC300 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.

Why is my SC300 A/C blowing hot air?

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.

What causes A/C system leaks?

Over the years, the rubber seals and gaskets in your SC300’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 my SC300 A/C run on gas?

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 SC300.

What does it mean if the A/C in my SC300 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 SC300 creates a breeding environment for microorganisms.

Why does my SC300’s A/C only work when the car is moving?

Damaged or worn components in your SC300’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 Repair Service for Your Lexus SC300

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. “Who can fix my Lexus SC300 A/C?” you wonder, as the sun beats through the windshield. Easy — Firestone Complete Auto Care! We know Lexus vehicles, and our technicians are qualified to diagnose and repair 1999 Lexus SC300 A/C systems. Steer your Lexus SC300 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 1999 Lexus SC300 A/C system to see if repair work is required. This check will include an examination of system pressure, a visual inspection, and a leak test. 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 Lexus SC300 A/C system to identify points where refrigerant fumes could be escaping the system. If there's a leak, we'll find it and fix it.

SC300 A/C Recharge

Let's say we repair your 1999 Lexus SC300 A/C system. We will also perform 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 perform an evacuation (also known as a discharge) on the entire system per Lexus guidelines. Finally, we’ll recharge the A/C system with new refrigerant and once the technician tests the cool blast for themselves, you’re good to go. We want you to be comfortable in your car, so we train our technicians to perform 1999 Lexus SC300 A/C recharges.

Troubleshooting Lexus SC300 A/C Problems

Warm air isn't the only Lexus SC300 A/C problem you may encounter. Other common A/C problems include 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. An A/C system that starts off blowing cold air but then turns warm may suggest a leak, a blown fuse, or a damaged compressor clutch. And smelly A/C in a 1999 Lexus SC300? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. 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 SC300 — without all the sweat puddles!
