Brake lights do not come on when brake pedal is pressed. Need directions on how to check the fuse or fuses, the brake light switch, etc. Thanks.

Good afternoon.

The brake light switch is under the dash at the brake pedal. I attached a wire diagram for you to view. There is a fuse listed for the switch in the underhood fuse block.

You will need a test light or voltmeter to check for power on both sides of the fuse.
