Lexus LS400 A/C Repair

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 LS400 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care can! We know our way around Lexus vehicles, and our trained technicians can identify and repair issues with 1991 Lexus A/C systems. Come to your local Firestone Complete Auto Care in your Lexus LS400

In this A/C performance inspection, we’ll check out the current condition of your 1991 Lexus LS400 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 think there might be a leak, we'll run a special U/V dye through the system or use a "sniffer." A "sniffer" is a machine that's run along parts of your Lexus LS400 A/C system that can identify points where refrigerant fumes could be escaping the system. If there's a leak, we'll find it and fix it.

LS400 A/C Recharge

When we perform an A/C repair on your 1991 Lexus LS400, 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 good to go. We want you to be comfortable in your car, so we train our technicians to perform 1991 Lexus LS400 A/C recharges.

Troubleshooting Lexus LS400 A/C Problems

You may think warm air is the only potential Lexus LS400 A/C problem you’ll have, but you may notice other issues, too. Typical A/C problems also 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 can mean there’s a malfunctioning compressor clutch, a leak, or a blown fuse. What about those (somewhat unpleasant!) smells coming through the A/C vents in your 1991 Lexus LS400? That could be the result of a dirty cabin air filter (an easy fix!) or a moldy evaporator case. Our trained technicians will do what they can to solve your A/C problems. Don’t sweat it — we’re here to help you chill out again in your LS400.

1991 Lexus LS400 A/C System FAQs

  • Can I make my LS400 air conditioner colder? Here are a few quick ideas. Shut the passenger air vents and point the other vents directly toward you. Park your car in the shade and use a window sun blocker. Then visit Firestone Complete Auto Care for an A/C performance check and recharge.
  • Why is my LS400 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? To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your LS400’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  •  Does the A/C in my LS400 use 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 LS400.
  • What can cause the A/C in my LS400 to smell like vinegar? 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 LS400 to produce a vinegary odor.
  • Why does my vehicle have to be moving for my LS400’s A/C to work? Damaged or worn components in your LS400’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.
