Because, few things are more frustrating than trying to drive with a fogged-up or frosted windshield. So in this blog the expert at In and Out Tire Pros review why the window defroster in your vehicle may stop working and what you can do to fix it.

Common Reasons Your Defroster Fails

When your car’s defroster isn’t working, it affect both your safety and others sharing the road. Because, a defroster is vital for clear visibility, especially during colder months or in humid conditions. So, let take a look at why your defroster might stop working and what you can do about it.

Blower Motor Problems

The blower motor is responsible for pushing air through the vents. So, if it’s malfunctioning or completely dead, the defroster won’t work properly.

Blocked or Damaged Vents

Dirt, debris, or damaged vent components can restrict airflow. And this will reduce the defroster’s efficiency.

Low or Contaminated Coolant

Your car’s defroster relies on warm air from the engine’s cooling system. And, low or old coolant can disrupt heat transfer, leaving the air cold.

Faulty Thermostat

A malfunctioning thermostat can prevent the engine from reaching its optimal temperature. And this will reduce the warmth needed for effective defrosting.

Broken Heating Elements or Wiring

Rear window defrosters rely on heating elements embedded in the glass. And if these are damaged or if wiring is faulty, the defroster won’t function.

AC System Issues

While it might sound counterintuitive, the air conditioning system helps remove moisture from the air during defrosting. So, if your AC isn’t working, your defroster may struggle to clear the windshield.

What to Do If Your Defroster Stops Working

Check the Basics

Inspect your vents for blockages and ensure your coolant level is adequate. And top it off if necessary. But be sure you use the correct type for your vehicle.

Turn on the AC

Even if it’s cold outside, running your air conditioning can help remove moisture from the air. And this makes defrosting faster and more effective.

Inspect Fuses

A blown fuse could be the culprit, especially if the blower motor or rear defroster isn’t functioning. So, check your owner’s manual for the fuse location.

Test the Blower Motor

If no air is coming out, it’s likely a blower motor issue. So, you’ll need the ASE certified mechanics at In and Out Tire Pros on Betts Pond Road in Millsboro to diagnose and repair it.
