How can I make my Riviera 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 Riviera 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?

Over the years, the rubber seals and gaskets in your Riviera’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 Riviera rely on gas?

The air conditioning system in your Riviera does not use gasoline directly as a fuel source, but it does require some power from the engine, which indirectly affects your car's fuel consumption.

What does it mean if the A/C in my Riviera smells like vinegar?

If the air conditioning in your Riviera 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.

What is causing my Riviera’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 Riviera may have a faulty cooling fan or low refrigerant.

Buick Riviera A/C Repair

When you get in the car on a hot summer day, the last thing you want is a broken air conditioner. Is that a hot stove? Nope, just your steering wheel. Sweat soaks the driver's seat. You wipe your brow and wonder, "Who can fix the A/C in my Buick Riviera?" Firestone Complete Auto Care — that’s who! We know our way around Buick vehicles, and our qualified technicians can diagnose and service the A/C system in your 1991 Buick. Steer your Buick Riviera to your nearest Firestone Complete Auto Care

During this initial A/C performance check, we’ll look at the state of your 1991 Buick Riviera’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 think there might be a leak, we'll run a special U/V dye through the system or use a "sniffer." A “sniffer” isn’t a technician with a good nose! It’s a machine that’s used on different parts of your Buick Riviera A/C system to detect refrigerant fumes escaping from the system. If your A/C system has a leak, we’ll find and repair it.

Riviera A/C Recharge

While your 1991 Buick Riviera’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. Next, they will evacuate the system according to Buick's recommendations. Finally, we’ll recharge the A/C system with new refrigerant and after one final test to be sure the system is cooling properly, you’re good to go. Our technicians are trained to efficiently perform 1991 Buick Riviera A/C recharges.

Other Buick Riviera A/C Problems

Warm air isn't the only Buick Riviera A/C problem you may encounter. Other common A/C problems 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 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 1991 Buick Riviera? 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. We’re here to help you get back on the road in your Riviera — without all the sweat puddles!
