Board inside of fuse block was burnt and the defogger relay prongs are shorted hot. This board looks simple but I can't get it to work right again so it's definitely a new fuse block for me. Wonder if the board went bad first and caused the fuse fire or if the fuse fire failed the board? My guess would be board failed.

Found the problem. The picture is of the fuse for the rear winder defogger. I think is melted the fuse panel somehow and shorted the fused leg of the mirror heaters to power. The only way to turn them off is to remove the fuse. Removing the relay does NOT shut them off. The other leg of that fuse is jammed in and i can't get it out. Does anyone know if the fuse block can be opened up once it's pulled out? I don't know if heated mirrors is worth a $200 fuse block replacement right now.

Now that I think about it, it's probably a relay stuck as they wouldn't draw a constant power if the glass was shorted. Anyone know where I can get a wiring diagram?

So my trucks been draining the battery. Thought it was a bad battery until the brand new AGM battery died too. Did a load test and found it was pulling 2.6 amps when asleep. Started pulling fuses and found #51 underhood for the heated mirror was all of the draw (but 0.006A). How do i go about finding the short? Is the rear defroster on the same circuit? Do i have to pop the glass off or is there a harness connector some where that i can use to determine which side it is and / or unplug so the other works for now (it's really cold out). Any chance that it's just dirty or something or am I definitely buying a new glass? How do you pop the glass out? Thanks

I can't edit my original post. Too Old. Mods can do as they see fit.

once we get a good list then we can cut and paste them all into one post and ask the mods to pin it. Post #3 is all about fog lights. I haven't read it because i have fog lights on my z71 but it lookes like the info needed is right here.

Can Some of you Super-modders post up links to the best mods here in just a summary format the puts it all in one place. This way it could potentially be pinned and make a real good reference. Thanks

check the cables. I've had to replace both of them several times because i never use the brake and inspection then fails it. The cables freeze up then don't put enough force on the brakes
