The rear defroster fuse is typically located in the vehicle’s fuse box. The exact location of the fuse will vary depending on the make and model of your vehicle, but it should be labeled as “defrost” or “defroster.” To locate the fuse box, open up your glove compartment, look behind kick panels near the floorboards, or search under your dashboard or steering wheel.
If you can’t find a label indicating which one is for your rear defroster, consult with an automotive technician for assistance. Once you have identified where it is located, remove and inspect the fuse to see if it needs replacement.
Most cars have a rear window defroster to help clear frost and fog from the back windshield. The fuse for this component is typically located in the fuse box under the dashboard or under the hood, depending on your make and model of car.

What Causes Rear Defrost to Stop Working?
There are a few potential causes of rear defrost malfunction. One of the most common issues is a faulty heating element, which can cause your rear window to stop de-icing and fogging up. This problem can be caused by worn out or corroded wiring in the circuit board, or it may even be due to an electrical fault such as loose connections between the car’s fuse box and its battery.
Another possible cause could be a blocked drain tube that prevents condensation from draining away from the vehicle properly and causing excessive moisture build up on the inside of your car’s windows. Finally, if you’re experiencing problems with your air conditioning system, this too could lead to issues with rear defrosting – as warm air being circulated through your cabin will reduce visibility and make it difficult for heat to escape through your windows.
How Do You Troubleshoot a Rear Window Defroster?
Troubleshooting a rear window defroster can be a tricky process, but there are some basic steps that you can take to get your vehicle up and running again. First, check the fuse box for any blown fuses related to the defroster. If you find one, replace it with an exact replacement as listed in your owner’s manual.
Next, inspect the wiring harnesses and connectors leading from the fuse box to make sure they are all connected properly. If they seem loose or disconnected then reattach them securely. Finally, if none of these steps seem to help then it is possible that there could be something wrong with the heating element itself inside of the rear window glass panel.
In this case you may need to remove the entire back windshield in order to gain access and examine it further for any visible damage or corrosion which could be causing a short circuit within its circuitry. Depending on how much experience you have with car repair jobs like this one you may want to consider consulting a professional mechanic who will know exactly what needs done in order to restore full functioning of your rear window defroster once again!
Where is the Rear Defroster Located in a Car?
The rear defroster is an important safety feature that helps to keep your car’s windows clear of fog, ice and snow. Most cars have a rear window defroster located in the center of the back glass. It usually looks like either a mesh grid or small rectangles that run across the entire width of the back window.
The electrical current running through this unit heats up wires which then melts any frost or ice on the outside surface of the glass so that you can see clearly out of your back window while driving. Depending on your make and model year, you may also find additional rear defrosters at each corner near where side mirrors attach to vehicle body. In addition, some vehicles now come with heated side mirrors as well as dedicated lines for connecting them directly to rear defrost system.
Why is My Rear Windshield Heater Not Working?
If you have noticed that your rear windshield heater isn’t working, then the first thing to do is to check for any visible signs of damage or wear. This could include cracked wires, loose connections, or broken elements in the glass. If there are no obvious issues present, then it’s likely that something else may be causing the issue.
Common causes of rear windshield heater not functioning correctly can range from a blown fuse to a faulty thermostat or an overheating motor. It is important to ensure that all components related to the heating system are inspected and thoroughly tested before attempting any repairs yourself. Additionally, if you’re concerned about safety while driving in cold weather conditions, it might be best to take your vehicle into a professional auto repair shop for further diagnosis and repair as soon as possible.

How to Test Rear Window Defroster
Testing the rear window defroster is a simple task that can help you identify any potential problems with your vehicle. To test your rear window defroster, start by turning it on and allowing it to run for about 5 minutes. Afterward, inspect the rear window glass for even heating and make sure all parts of the grid are active and working properly.
If any part of the grid appears inactive or if there is an uneven pattern in the heated area then you should have a qualified mechanic inspect it further as this could indicate defective wiring or other issues.
How Much Does It Cost to Fix Rear Defroster
