Tail lights work, turn signals work, fuse and brake light switch are new and working....what is going on here? How do i fix this? does a chevy this old have a brake light relay?
have you checked your brake light switch located on the upper part of the foot brake, if it is out of adjustment or defective you will not have brake lights..
Have you check the fuses. Sometimes when people have a trailer connection for lights etc. it is easy to blow the brake light fuse. or someone screwed up the wiring and it came loose, check any electrical wiring that has been spliced for your trailer connection. You said the turn signals work, that means the bulb is good because it is a double element. (brighter)
Do the brake lights illuminate when you jumper the brake light switch? If they do the switch is installed wrong. Next step is to check for 12 volts at the switch with a voltmeter or test light. No power it's time to trace power from the fuseblock. It could be a faulty electrical plug.
