Everyone has experienced that frosty morning. You then search for your car’s built-in help—your defroster—because your windshield is covered with ice and your wipers are frozen.
Defroster plays a significant role in each person’s winter mornings. So, it makes sense that you might search “Why is my defroster not functioning?” if the defroster in your Ford F-150 is not working correctly.
In this article, find out why a defroster in your Ford vehicle is not working and what you can do about it!
What Causes Rear Defrost To Stop Working In Ford F-150?
You may check a few things before sending your Ford F-150 to a technician if your defrost needs to be fixed.
Ensure the temperature knob is fully cranked to the “hot” setting. Turning up the heat could be all that’s necessary to solve the issue.
You can try a few more things if the temperature knob is in the correct position, but your defrost still isn’t working.
Ensure your car’s vents are wide open to allow air to circulate freely.
Additionally, investigate if there is a particular option for the defrost in your car’s owner handbook.
However, continue reading for other typical problems if you need more suggestions to resolve your issue.
A blown fuse, a loose connection, or an issue with the switch or grid may be to blame for your rear window defroster not working.
Here’s how to fix the problem so you can regain your heat.
Cause & Fix #1. A Blown Fuse
Check the fuse first.
A fuse has likely blown since the rear window defroster often shares a circuit with the side mirrors and cigarette lighting.
Depending on your Ford model, you can locate the fuse box in the engine or passenger compartment.
Replace the fuse with a new one that has the same amperage.
Cause & Fix #2. Loose Connections
If the fuse is not the problem, look for any loose connections.
Over time, the wires that attach to the grid on your back window may become loose, interrupting the flow of electricity.
Examine the connections, and if required, tighten them.
Cause & Fix #3. Issues With The Switch Or A Grid
If neither of those fixes described above succeeds, there can be an issue with the switch or grid itself.
It’s recommended to take your automobile to a technician or auto shop for additional diagnostic and repair.
How Much Does It Cost To Fix Rear Defrost In Ford F-150?
Depending on several variables, the typical cost to repair the rear windshield on your Ford F-150 might vary by a few hundred dollars.
This covers the source of the components, the tools needed, and who performs the replacement.
Easily anticipate spending anything between $90 and $698.
However, the typical price ranges from $389 to $463. Costs for labor range from $103 to $236. It will take approximately an hour or two to replace the broken parts.
How Can I Make My Rear Window Defrost Faster In Ford F-150?
If your defrosting settings need to be fixed faster than you’d like them to, here are a few tips to make the defrosting process quicker!
1. Combine 2/3 isopropyl or rubbing alcohol and 1/3 water.
2. Spray this solution on your windshield in the morning; the ice should go right away.
…or try alternative ready-made options from your nearest dealership or check into a portable defroster if you’re seeking other ways to defrost your windshield.
But that’s not it!
Did you know that you may altogether avoid the problem of frosted windows? That’s possible with accessories like a windshield cover, with which you can stop frost from ever forming on your front windshield.
The frost-blocking cloth covers your windshield, and the product hooks over the side-view mirrors on your car.
If the shield becomes frost-covered, you detach it, shake it to the ground, and store it in your car or garage.
