How can I make my GS400 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.

What’s making my GS400 A/C put out warm 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 can cause an A/C system leak?

Over the years, the rubber seals and gaskets in your GS400’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 the A/C in my GS400 rely 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 GS400.

What does it mean if the A/C in my GS400 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 GS400 creates a breeding environment for microorganisms.

What is causing my GS400’s A/C to only work when the car is in motion?

There could be issues with one or more components in the air conditioning or electrical system. Your GS400 may have a faulty cooling fan or low refrigerant.

Lexus GS400 A/C Repair

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like lava. Your skin sticks to the driver’s seat. You wipe your brow and wonder, "Who can fix the A/C in my Lexus GS400?" Firestone Complete Auto Care — that’s who! We know Lexus vehicles, and our trained technicians can identify and repair issues with 1998 Lexus A/C systems. Bring your Lexus GS400 to your local Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 1998 Lexus GS400 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. A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Lexus GS400 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.

GS400 A/C Recharge

Let's say we repair your 1998 Lexus GS400 A/C system. We will also perform an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Lexus guidelines. 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. Our technicians are trained to efficiently perform 1998 Lexus GS400 A/C recharges.

Troubleshooting Lexus GS400 A/C Problems

Warm air isn't the only Lexus GS400 A/C problem you may 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. 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. And smelly A/C in a 1998 Lexus GS400? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our technicians will work to solve your A/C problems to the best of their ability. Don’t sweat it — we’re here to help you chill out again in your GS400.
