A/C Service for Lexus LS400

Few things are worse than a broken car air conditioner on a hot summer day. Your steering wheel feels like it's burning your hands. Sweat soaks the driver's seat. You take a deep breath and ask yourself, “Who can fix my Lexus LS400 A/C?” Firestone Complete Auto Care — that’s who! We know Lexus vehicles, and our technicians are qualified to diagnose and repair 1990 Lexus LS400 A/C systems. Steer your Lexus LS400 to your nearest Firestone Complete Auto Care

During an A/C performance check, we'll determine the condition of your 1990 Lexus LS400 A/C system to determine whether repair work is needed. 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. What’s a “sniffer,” you ask? It’s a specially designed machine that’s used on parts of your Lexus LS400 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.

Recharge the A/C in Your LS400

When we perform an A/C repair on your 1990 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 the technician tests the cool blast for themselves, you’re all set. Our technicians are trained to efficiently perform 1990 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. Another common A/C problem is weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. If you notice that your A/C system’s air is cold at first, then quickly goes warm, this 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 1990 Lexus LS400? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Our trained technicians will do what they can to solve your A/C problems. We’re here to help you get back on the road in your LS400 — without all the sweat puddles!

1990 Lexus LS400 A/C System FAQs

  • Can I make my LS400 air conditioner 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 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 my LS400 A/C use gas? Your LS400’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.
  • Why does the A/C in my LS400 smell like vinegar? If the air conditioning in your LS400 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 LS400’s A/C cool the vehicle when the car is stopped? 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.
