Hey guys, I have a 2013 FX4 that is the more stripped down version with the solid rear window. Since purchase, 3 of the lower defrosters strips do not work. Does anyone have an idea of how to fix such an issue? I have done some searching through the forums and it seems all the defrost issues I find are in relation to trucks with the rear sliding glass, which I don't have. Any thoughts would be appreciated.

 

They used to sell a touch up paint to repair defrost strips. Check your local auto parts stores and check and see if they still sell it.
