Don't forget to check vehicle's climate control system prior to travel.
Your vehicle’s climate control system not only makes for an inviting interior but also plays a crucial role in travel safety.
Winter can be harsh on your car, and one of the most critical components to ensure your comfort and safety during this season is your climate control system.
Are your vehicle’s heating and defrosting systems working properly?
“The most obvious sign your car’s climate control system needs attention is that the A/C or heater aren't working or are working poorly,” says Tony Molla, VP of Communications at the National Institute for Automotive Service Excellence. “You may also get a warning on the driver information system if the vehicle is equipped with that feature.”
Neglecting regular maintenance on your climate control system often leads to performance issues. Regular check-ups and noticing the signs of potential issues can help prevent the likelihood of you stranded on the side of the road in the middle of winter without a working heater.
Molla offers the following signs that signal a car's climate control system isn't working efficiently:
- Unusual noises or odors in the vehicle. Foul odors could indicate the presence of mold in the climate control system.
- Noises when you activate the climate control system. This could indicate an issue with drive belts or compressor problems.
- Heating system isn't working as expected. Your vehicle may be low on coolant. It also may have a problem with the temperature sensor or heater control valve.
There are also a few steps Molla says you can take to help prevent any issues with your car’s climate control system.

“Ask your service advisor to check for and clean any debris from the air intakes on the hood cowling,” says Molla. “Things like leaves can block the air intake located below the windshield wipers along the rear of the hood area.”
Critters like mice or squirrels may take up residence under the hood of your vehicle or build a nest if your vehicle sits idle for days.
Common signs your climate control system needs an inspection:
- Ineffective heating: The most obvious sign is a lack of warmth inside your vehicle. If your car's heater isn't producing sufficient heat or takes an unusually long time to warm up, there might be a problem with the system.
- Weak airflow: Reduced or uneven airflow from the vents could indicate blockages or issues with the ventilation system.
- Inadequate defrosting: The defrosting system is crucial for maintaining visibility during cold weather. If your windshield takes too long to clear or doesn't clear at all, it may signal there’s a problem.
- Inconsistent temperature control: If you set the temperature to a specific level, but it fails to maintain a steady temperature in the cabin.
- Leaking coolant or antifreeze: Keep an eye on your coolant or antifreeze levels. If you notice a consistent drop, it might indicate a leak in the heating system's core.
- Condensation or fog inside the car: Excessive condensation or fog on the inside of your windows could mean there is a problem.
“Aside from these issues, always have your heating system, air cleaners, belts, hoses and coolant levels checked by a service professional in fall or early winter to catch any issues before they become a major issue in inclement weather,” says Molla.
“It's also a good idea to have your battery checked to make sure it's fully charging and operating properly. Don't forget to check the cabin air cleaner if your vehicle is equipped with one as well.”
