Where is the multifuction switch that was talked about reguarding another S10. My brake lights don't work but my third brake light does. So I'm assuming the switch is okay because the upper third light works. I understand that the third is on an independent dedicated circuit. I found the hazard/flasher control box in the wiring diagram but can't find it in the truck.
