Turn signals and brake lights not working

Hi,

The first things I need you to check are two fuses. If you look at the first two pics below, I included the wiring schematic for the exterior lighting system. In the first pic, I highlighted the fuses. In pic 2, I highlighted the lights and I circled the ground. Both lights are grounded at the same place, so the ground may have failed.

If you look at pic 3, I highlighted the fuses to check. In addition to checking the fuses, confirm there is power to them. Here is a link you may find helpful:

If the fuses are good and you have power to and from them, go to the taillights and using a test light and a known good ground, confirm there is power. If there is, then check the black wire for continuity to ground.

Let me know if when you turn the signals on if the front flash really fast or if they do nothing.

Take care,

Joe
