My brake lights are not working. The turn signals, both right and left work with brand new bulbs, but when pressing on the brake pedal, the lights do not come on.

Hello,

There are a couple fuses and a brake light switch we need to check. There is also a brake light control module which controls the brake light system as well. Here are guides to help us get started to get the problem fixed:

Below are the brake light wiring diagrams and the pedal configuration. Let us know what happens and please upload pictures or videos of the problem.

The brake light fuse was blown due to a melted light socket. We I replaced with one from the parts store fixed it.
