2018 Chevrolet Silverado 2500 electrical problems

ELECTRICAL SYSTEM

Rear defroster seemed to short circuit and over heated causing my back window to break. There was no warning, no light that alerted me to this going on. I had it inspected by a local Chevy dealership and they have indeed confirmed that it short circuited and caused the damage to my rear window. They also removed the fuse to prevent anything further from happening and told me it could have completely caught on fire.
