Why is your car heater underperforming this winter?

Understanding the Problem

Have you noticed your car heater isn’t pumping out warmth like it should? You’re not alone. Many drivers experience underperforming heaters during the colder months. Let’s explore why this might be happening and what you can do about it.

1. Low Coolant Levels

“I thought I filled it up!” you might say. Lack of coolant can lead to poor heating. The heater core needs coolant to work correctly. If it’s low, warm air won’t circulate into the cabin.

“How do I check it?” you ask. It’s simple! Open the hood and find the coolant reservoir. If it’s below the “Low” line, add coolant.

2. Thermostat Issues

Is your engine running cold? It could be a faulty thermostat. “But what does that mean?” you might wonder. The thermostat controls the flow of coolant. A stuck-open thermostat means coolant circulates too freely, never allowing the engine to warm up.

“Can I fix it?” Yes, but it’s usually best to let a mechanic handle it.

3. Clogged Heater Core

If this happens, your only choice may be flushing the system or replacing the heater core entirely. Not a fun task.

4. Faulty Blower Motor

Is the fan blowing air, but it’s cold? “That’s frustrating!” you might exclaim. The blower motor can stop working correctly or get clogged with debris.

Check if you hear any strange noises. If it’s silent or weak, the motor may need a replacement.

5. Air Leaks in the Cabin

“Why is cold air sneaking in?” you may wonder. Gaps around your doors or windows allow outside air in. This can make it hard for the heater to keep things warm.

Inspect your door seals. If they feel brittle or cracked, consider replacing them.

6. Using the Wrong Settings

“Could I be doing it wrong?” It’s possible. Ensure you’re using the correct heater settings. If you have the AC on or not directing the airflow properly, you won’t feel the heat.

“So what should I do?” Switch to heat mode, set the fan to high, and direct airflow toward the windshield or feet.

7. Please Get It Checked

Feeling a little overwhelmed? It’s normal! If you’ve tried the basics and your heater still underperforms, it’s time to contact a professional. “How do I find someone?” you might ask.

Look for a trusted mechanic or a supplier in your area. They can diagnose the issue and suggest repairs or replacements.
