As the winter season approaches, it becomes essential to ensure that your car’s defroster is in perfect working condition.
It helps clear foggy or icy windshields, significantly improving visibility while driving. However, there may come a time when your defroster stops functioning properly, leaving you struggling to see clearly.
In this article, we will explore what you can do if your defroster doesn’t work, providing you with practical tips and solutions.
Common Causes of Defroster Malfunctions
Before we delve into troubleshooting techniques, it is important to understand the potential causes of a malfunctioning defroster. Some common issues include:
- Blown Fuse: Check the fuse box and replace the defroster fuse if it is blown.
- Faulty Wiring or Connection: Examine the wiring and connections behind your vehicle’s dashboard for any loose or damaged wires.

Troubleshooting Your Defroster
Now that we have identified some common causes, let’s discuss a few troubleshooting techniques to help fix your defroster:
