We have checked the orange wire that runs from the switch to the lamp fuse and there is power to both ends. We have replaced the switch itself and the light bulbs. There is power going back to the brake lights but they still do not light up when I press the brakes. What should I check next? Please Help

if your trac light is on then have it scanned for an abs code as it knocks off the traction control when something is amiss on abs unit or sensors. check lt/blu wire leaving switch if power there then go to rear fuse block and check to see if same color wire is leading power in and out of fuse block it is under the right rear seat. finally see if it is reaching tailight if it is then check ground for tailight which should be a black wire.
