Can I make my D21 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 D21 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 causes A/C system leaks?

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 D21's A/C system.

Does the A/C in my D21 use gas?

Your D21’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 D21’s A/C smells like vinegar! What can cause that?

If the air conditioning in your D21 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 does my D21’s A/C only work when the car is moving?

If your A/C only works when the vehicle is moving, there could be a problem with part of your D21’s A/C or electrical system. Potential issues include low coolant or a faulty cooling fan.

A/C Repair Service for Your Nissan D21

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 lava. Your skin sticks to the driver’s seat. “Who can fix my Nissan D21 A/C?” you wonder, as the sun beats through the windshield. Firestone Complete Auto Care — that’s who! We know Nissan vehicles, and our trained technicians can identify and repair issues with 1991 Nissan A/C systems. Bring your Nissan D21 to your local Firestone Complete Auto Care

In this A/C performance inspection, we’ll check out the current condition of your 1991 Nissan D21 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. A "sniffer" is a machine that's run along parts of your Nissan D21 A/C system that can detect any refrigerant fumes that might be leaking out from the system. If your system has a leak, we can get it fixed.

A/C Recharge for Nissan D21

While your 1991 Nissan D21’s air conditioner is being serviced, we’ll also do 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 Nissan's recommendations. Finally, we’ll recharge the A/C system with new refrigerant and once the technician tests the cool blast for themselves, you're ready to get back on the road. Our technicians are trained to efficiently perform 1991 Nissan D21 A/C recharges.

Troubleshooting Nissan D21 A/C Problems

You may think warm air is the only potential Nissan D21 A/C problem you’ll have, but you may notice other issues, too. Typical A/C problems also include weak airflow, which could indicate an old ventilation fan, a seal or hose that needs replacing, or mold buildup in your A/C system. 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. Are you breathing in some “interesting” new odors in your 1991 Nissan D21? You could have a moldy evaporator case, or you may simply need a new cabin air filter installed. Technicians at Firestone Complete Auto Care are ready to help you address your A/C problems. Don’t sweat it — we’re here to help you chill out again in your D21.
