2013 F150 Rear Defroster Not Working
Last Updated on by Tarek
A functional rear defroster is essential for maintaining clear visibility and safe driving conditions, particularly during colder months or inclement weather. If you find that the rear defroster on your 2013 Ford F150 is not working,
It’s crucial to diagnose and resolve the issue as soon as possible to ensure a safe and comfortable driving experience.
The following guide will provide you with a step-by-step troubleshooting process to identify the root cause and suggest potential solutions to fix your rear defroster problem.
The F150 Rear Defroster Troubleshooting
If your 2013 Ford F150’s rear defroster is not working, there are several possible causes that you can investigate. Here’s a step-by-step troubleshooting guide to help you diagnose and potentially fix the issue:
Check the fuse:
The first step is to locate the fuse box, which is usually under the dashboard or in the engine compartment. Consult your owner’s manual to find the exact location and the correct fuse for the rear defroster. If the fuse is blown, replace it with a new one of the same amperage.
Examine the defroster switch:
If the fuse is intact, the issue could be with the defroster switch. Start the engine and press the defroster button. If the indicator light does not come on, the switch might be faulty and may need to be replaced.
Inspect the rear defroster grid:
The rear window defroster grid consists of horizontal lines that heat up when the defroster is activated. Check for any damaged, broken, or disconnected grid lines. If you find any damage, you can use a defroster repair kit to fix the broken lines.
Test the defroster relay:
If the switch and grid lines appear to be in good condition, check the defroster relay. You can locate the relay in the fuse box, usually labeled as “REAR DEF” or similar. Swap the relay with another relay of the same type, then test the defroster. If it now works, the original relay is likely faulty and should be replaced.
Check the wiring:
Inspect the wiring connecting the defroster switch, relay, and rear defroster grid. Look for any signs of damage, corrosion, or disconnected wires. Repair or replace any damaged wiring.
Examine the defroster tabs:
The defroster grid connects to the vehicle’s electrical system through defroster tabs. These tabs are usually located at the sides of the rear window. Ensure they are securely connected to the defroster grid and free of damage or corrosion.
Test the voltage:
If all the previous steps haven’t resolved the issue, use a multimeter to test the voltage at the defroster tabs when the defroster is activated. If there is no voltage or it is too low, the issue could be a wiring problem or a malfunctioning switch.
Seek professional help:
If you are unable to diagnose the issue or feel uncomfortable performing any of these steps, consult a professional auto mechanic. They will have the necessary expertise and tools to properly diagnose and fix the problem.
Remember to always consult your vehicle’s owner’s manual and follow safety precautions while troubleshooting and repairing your rear defroster.

Common Causes of Rear Defroster Failure and Fix Guide
Rear defroster failure can occur due to various reasons. Here are some common causes of rear defroster failure:
Blown fuse:
A blown fuse is often the most common cause of rear defroster failure. The fuse protects the electrical system by breaking the circuit if there’s an overload. Check the fuse for the rear defroster and replace it if it’s blown.
Solution: Locate the fuse box, usually under the dashboard or in the engine compartment. Consult your owner’s manual for the correct fuse related to the rear defroster. Replace the blown fuse with a new one of the same amperage.
Faulty switch:
The switch responsible for activating the rear defroster may be faulty or damaged. If the switch doesn’t light up when pressed or doesn’t activate the defroster, it may need to be replaced.
Solution: If the defroster switch doesn’t work, it may need replacement. Consult your vehicle’s repair manual for guidance on replacing the switch or visit a professional auto mechanic for assistance.
Damaged defroster grid:
The rear defroster grid consists of conductive lines on the rear window that heat up when the defroster is activated. Over time, these lines may get damaged or broken, causing the defroster to fail. You can use a defroster repair kit to fix any broken lines.
Solution: Use a defroster repair kit to fix any broken or damaged lines in the rear defroster grid. Follow the kit’s instructions carefully for the best results.
Defective relay:
The relay is an essential component in the rear defroster’s electrical system. If the relay is defective, it may prevent the defroster from working. Test the relay by swapping it with a known working one, and replace it if necessary.
Solution: Locate the relay in the fuse box, typically labeled as “REAR DEF” or similar. Swap the relay with another working one of the same type. If the defroster now works, replace the faulty relay.
Wiring issues:
Damaged, corroded, or disconnected wiring can cause the rear defroster to fail. Inspect the wiring connections between the defroster switch, relay, and rear defroster grid. Repair or replace any damaged wires.
Solution: Inspect the wiring connections between the defroster switch, relay, and rear defroster grid. Repair or replace any damaged, corroded, or disconnected wires as needed.
Defroster tabs:

Solution: Examine the defroster tabs, which connect the defroster grid to the vehicle’s electrical system. If the tabs are damaged, loose, or corroded, clean them with a soft cloth and a gentle cleaner, or replace them if necessary.
Inadequate voltage:
If there’s the insufficient voltage at the defroster tabs when the defroster is activated, the system may not work correctly. This issue could stem from a wiring problem, a malfunctioning switch, or another electrical issue.
Solution: Use a multimeter to test the voltage at the defroster tabs when the defroster is activated. If the voltage is too low, investigate potential wiring problems, a malfunctioning switch, or other electrical issues. Consult a professional auto mechanic if needed.
Malfunctioning timer:
Some vehicles have a built-in timer that automatically shuts off the rear defroster after a specific period. If this timer is malfunctioning, it may cause the defroster to stop working prematurely.
Solution: If the rear defroster timer is malfunctioning, consult your vehicle’s repair manual for guidance on replacing the timer or seek assistance from a professional auto mechanic.
Window tint interference:
Aftermarket window tint can sometimes interfere with the proper function of the rear defroster. The tint may be too thick, causing the defroster grid not to heat up properly, or it may have been improperly installed, damaging the grid lines.
Solution: If aftermarket window tint is causing defroster failure, consider removing the tint or replacing it with one that is compatible with your rear defroster system. Consult a professional window tinting service for proper installation.
If you’re experiencing rear defroster failure, consider these common causes and follow a step-by-step troubleshooting process to diagnose the issue. If you’re unable to identify or fix the problem yourself, consult a professional auto mechanic for assistance.
