How can I make my RX300 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 RX300 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?

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 RX300's A/C system.

Does my RX300 A/C run on gas?

Your RX300’s A/C uses some power from the engine to run. So, while your air conditioning system may not directly use gasoline as a fuel source, using the A/C can indirectly affect your vehicle’s fuel efficiency.

My RX300’s A/C smells like vinegar! What can cause that?

It’s easy for moisture to accumulate in your car’s air conditioning system, which can cause microorganisms like bacteria to grow. In turn, this bacteria growth can cause the A/C in your RX300 to produce a vinegary odor.

Why does my vehicle have to be moving for my RX300’s A/C to work?

There could be issues with one or more components in the air conditioning or electrical system. Your RX300 may have a faulty cooling fan or low refrigerant.

Lexus RX300 A/C Repair

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. That puddle in the driver’s seat? Sweat. Ugh. “Who can fix my Lexus RX300 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We’ve got experience with Lexus vehicles, and our qualified technicians can diagnose and service the A/C system in your 2003 Lexus. Come to your local Firestone Complete Auto Care in your Lexus RX300

During this initial A/C performance check, we’ll look at the state of your 2003 Lexus RX300’s A/C system to evaluate what repairs are necessary (if any). This check includes a visual inspection, performance test, and pressure and 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. A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Lexus RX300 A/C system to identify points where refrigerant fumes could be escaping the system. If your system has a leak, we can get it fixed.

Recharge the A/C in Your RX300

Let's say we repair your 2003 Lexus RX300 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. Next, they will evacuate the system according to Lexus's recommendations. The A/C system is recharged with new refrigerant and once the technician tests the cool blast for themselves, 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 2003 Lexus RX300 A/C recharges.

Common Lexus RX300 A/C Problems

You may think warm air is the only potential Lexus RX300 A/C problem you’ll have, but you may notice other issues, too. Other common A/C problems include 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. And smelly A/C in a 2003 Lexus RX300? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our technicians will work to solve your A/C problems to the best of their ability. So, chill out. We're here to help you get the blast back in your RX300’s A/C!
