How do I make my D21 air conditioning 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 D21 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.

How does my A/C system get a leak?

Over the years, the rubber seals and gaskets in your D21’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 my D21 A/C 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 D21.

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.

What is causing my D21’s A/C to only work when the car is in motion?

Damaged or worn components in your D21’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.

Nissan D21 A/C Repair

There’s nothing worse than cranking your car air conditioner on a hot day — and discovering it’s broken. Is that a hot stove? Nope, just your steering wheel. Your skin sticks to the driver’s seat. You take a deep breath and ask yourself, “Who can fix my Nissan D21 A/C?” Easy — Firestone Complete Auto Care! We know our way around Nissan vehicles, and our qualified technicians can diagnose and service the A/C system in your 1993 Nissan. Come to your local Firestone Complete Auto Care in your Nissan D21

During an A/C performance check, we'll determine the condition of your 1993 Nissan D21 A/C system to see if repair work is required. 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 refrigerant fumes escaping from the system. If there's a leak, we'll find it and fix it.

D21 A/C Recharge

When we perform an A/C repair on your 1993 Nissan D21, 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. The A/C system is recharged with new refrigerant and after one final test to be sure the system is cooling properly, you're ready to get back on the road. Our technicians are trained to efficiently perform 1993 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. Another common A/C problem is 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. If your A/C system blows cold air first but then it turns warm, this 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 1993 Nissan D21? This can mean you have mold in your evaporator case, or it may indicate that it’s time to change your cabin air filter. Our trained technicians will do what they can to solve your A/C problems. So, chill out. We're here to help you get the blast back in your D21’s A/C!
