I purchased the car used two years ago and I am just fixing what I can when I can.
All of my break lights are out can this have something to do with the ABS system on 1994 Pontiac Firebird
Not ABS, fuse, brake light switch, signal light switch can cause this as well even though the signals work ok! Possible wire problem also. Do four way flashers work? If so then it aint wires going to the lights! Same circuit feed. Best to check ALL fuses first with a test light!! Then the brake light switch if ok then see a mechanic!
