brake lights not working & blinkers sometimes quit working

"@perz for your non-functioning brake light you would start by checking the brake light switch on your brake pedal. Make sure that it is working (of course you checked the bulbs etc.)

The blinkers sometimes not working could be a n issue with corrosion on the ground wire etc. Check that all the wires going to the relay are in good working order as well. The location of the relay is on the right side of the steering column just above the diagnostics port"
