left brake light out when right signal is used
1973 chevy c10
both brake lights work, but when I use the right signal, the left brake light will not work but when I use the left signal, the right brake light works
Sounds like the turn signal switch is getting ready to fail. You can try spraying some contact cleaner in there and push and pull the 4Ways on and off a few times, see if that helps but it's not long before it fails completely.
