I just had the same exact problem with my blazer the lower two brake lights wouldnt work but the center upper one would.I brought the blazer to the gm dealer they charged me 140 bucks to tell me the multifunction switch went out. When I did a little research before hand to see what was going on. And figured that out myself, and I just brought it in to see how much they could do it for. They said 700 bucks and I just paid the 140 diagnostic fee and left.I went home and looked on ebaymotors for a multifunction switch for my blazer for 100 bucks including shipping I bought one on ebay, then brought it to a local shop and they installed it for 112. So yes you can rest assure there are ways around paying 700 bucks and and also rest assure that replacing the multifunction switch will aliviate the problem.
