Resetting The Window System To Fix WeatherTech Wind Deflectors Faults

If you are having issues with wind deflectors errors even after the top section of the window not touching them, then it might be an interior problem. A few people can’t able to close the windows after deflectors are installed which sometimes needs a simple reset to solve the hassle.

To fix that, we ask for only 1 minute that the problem will vanish by following the given instruction rightly. 

1. Start by, slowly enhancing the window up and be sure not to activate the auto-up feature.

2. Next, decrease the window so that it stays downward. After that, press the down button for up to 5-6 seconds. 

3. Then, raise the window just like you normally do. Make sure not to activate the auto-up function. Now, press the up button for 3-4 seconds. 

4. You want to do the same thing to other windows if they are faulty too. Let them sit there like for 12 hours long.

Pro Tip: The WeatherTech window deflectors take a longer time to adapt if the temperature of the truck is below 60° F (16° C).

Sanding Down Might Solve WheatherTech Window Deflectors Errors

The best trick that works to solve their problem is by sanding the top section of window deflectors. Especially if you are having trouble of bounce back while closing the windows, the sand down technique will do the work.


When placed in these positions, the clips help to push the deflectors out from the window. Then by leaving the deflectors, this will help to mould the deflectors to the shape of the window.

A lot of drivers have similar issues of bounce back for over 8-9 months after attaching the WeatherTech window deflectors and they find this solution very effective compared to others. So, what do you need to do?

Before you sand down the surface, it’s always better to adjust the clips of them to shape them in the right way. Also, try to raise up and down the window for a few seconds. 

The window deflectors usually have a 1/16” or 1/15” thickness on the top-side window that sometimes causes bounce back. To fix that, take a sanding machine or sander with a block and gently smoothen out the extra surface.

If you are able to minimize the 1/16”-1/15” depth, then the wind deflectors will work fine. Be sure not to hard the motor while doing so.

Wipe Down Grime To Fix Problematic WeatherTech Window Deflectors

Trapped debris is also a common thing that might result in the wind deflectors issue. Cleaning the messes around them might solve the error if you keep on doing that weekly.  

And also, be sure to wipe out the visible dirt using a cloth or tissue and clean the hidden grime with a brush that goes all over the window deflectors. Don’t use any liquid or water-soap solutions as this causes peelings.

Does your WeatherTech window deflectors not working fine after doing everything? If not, then you need to check how to install WeatherTech side window deflectors with clips. Follow the given instructions to replace the old one:

  • Clean the windows and lower the glasses in halfway.

  • Next, slide the deflector upward to the channel and bow it on outward.
