I drive a 09 GMC canyon SLE w/3.7L engine. I have done a search and have followed all the previous diagnosis for no brake lights which included changing out the bulbs the fuse AND the obvious brake light switch but still no brake lights.One thing i found today was when I hook up my boat, the trailer has brake lights but not my truck. I am so lost for what to look for. Does anyone have any clues?
Thanks
Bill
