Can I make my GS450h 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 is my GS450h A/C blowing hot 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.

What can cause an A/C system leak?

Over the years, the rubber seals and gaskets in your GS450h’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 GS450h A/C use gas?

GS450h 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.

My GS450h’s A/C smells like vinegar! What can cause that?

If the air conditioning in your GS450h 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 won’t my GS450h’s A/C cool the vehicle when the car is stopped?

There could be issues with one or more components in the air conditioning or electrical system. Your GS450h may have a faulty cooling fan or low refrigerant.

A/C Service for Lexus GS450h

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. Your skin sticks to the driver’s seat. “Who can fix my Lexus GS450h A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We know our way around Lexus vehicles, and our trained technicians can identify and repair issues with 2009 Lexus A/C systems. Steer your Lexus GS450h to your nearest Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 2009 Lexus GS450h A/C system to evaluate what repairs are necessary (if any). This check will include an examination of system pressure, a visual inspection, and a 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. What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your Lexus GS450h A/C system to identify points where refrigerant fumes could be escaping the system. If your A/C system has a leak, we’ll find and repair it.

A/C Recharge for Lexus GS450h

While your 2009 Lexus GS450h’s air conditioner is being serviced, 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 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 ready to get back on the road. We want you to be comfortable in your car, so we train our technicians to perform 2009 Lexus GS450h A/C recharges.

Other Lexus GS450h A/C Problems

Warm air isn't the only Lexus GS450h A/C problem you may encounter. Typical A/C problems also include weak airflow, which could be caused by mold or mildew buildup, a loose hose, an old ventilation fan, or a compromised seal. 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. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 2009 Lexus GS450h? 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. So, chill out. We're here to help you get the blast back in your GS450h’s A/C!
