I recently fixed a problem where the cruise control and brake lights stopped working at the same time in my 2006 GMC Canyon. The question is not how to fix this, but how it broke to begin with.
I removed the switches at the brake pedal and found that the switch for the brake lights (according to the wiring schematic in the Haynes book) had a lot of burnt residue inside the switch where contact was made between the two diodes. I am just wondering how it could have had enough power running between them to cause shorting/melting/burning when the fuse remained intact?
