Chevy Cav Brake light and blinkers don't work?

Hi I have a 2000 Chevy Cav 4 cylinder car. The problem that i am having is that my brake lights and blinkers no longer work. The running lights work fine.. I have already checked all the fuses and the light bulbs and there are no problems there.. What would be the recomended next step?

Thank you in advance..

get an ohmeter or any other thing to check for voltage and trace the wires until u see voltage present

check for loose connectors and ground too

if fuses and bulbs r ok must be a loose ground or a loose connection between wires
