I have a 2012 f150 with the back glass defrost not working. I’ve watched your video and others that bypass the back glass so the mirrors still have defrost. Some use a device to step down the voltage but I see didn’t. Just wanted to make sure you haven’t had any more issues.
@@Higgsgarage Yes I have an 11 Platinum 6.2L. bought hose from NAPA and the fitting broke with a bit of force when tried to take it apart. I have no crimps or fittings now, rubber goes right to the metal one piece tube.
@mrstl3000 that’s a good question. I’m familiar with it on the sliding ones only. I do not believe the solid back windows have heater grids in them but I could be wrong.
@@Higgsgarage I have full glass with rear defrost button don't see any grids in window though however it could have been replaced already from a sliding style
I am not entirely sure… I never diagnosed it because I wouldn’t use it in fear of the glass breaking. But, the button/light work flawlessly now so I am thinking it has some issue with the back heating element.
