It sounds like the #10 fuse in the under hood fuse panel is out or the drives MICU is out. But let's start with the easy stuff, here is a guide to help you check the fuses witht he fuse location in the diagrams below. I have included the brake light wiring diagrams and fuse locations so you can see how the system works.

All of my lower brake lights are out at the same time but the upper brake light is okay. The filaments in the brake lights look okay. All other lights and electrical are okay?

Hi bmanion,

It sounds like the turn signal hazard relay is not working correctly but to be sure here is a guide to help test for power with the brake light wiring diagrams along with the turn signal relay below.

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

Looking at the manual it does not indicate which fuse is used for the "brake lights." Without pulling every fuse how do I tell which one I should be checking.

You should check each fuse with a test light or multimeter. Sometimes the fuse schematics does not list every circuit that is on that particular fuse so it is always best to check all of the fuse.

Here is a guide to help you see how to check the fuses

https://www.2carpros.com/articles/how-to-check-a-car-fuse

Here are the fuse panel locations and identification

Check out the diagrams (Below)

Please let us know if you need anything else to get the problem fixed.

Cheers

We've checked the fuse. It is the same one as the horn. The fuse is fine and the horn works. All other lights work on the tale light. The brake lights just won't work. Help.

Hi there,

Check the brake light switch at the top of the brake pedal, remove plug and check for power and if OK bridge out plug with a paper clip or split pin and check for lights, if OK replace switch.

Good afternoon,

I attached a wiring diagram for you to view. You need to test for power to the brake light switch. In most cases, it is the switch that is bad.

Roy

1. Disconnect the 4P connector (A) from the brake pedal position switch (B).
2. Check for continuity between the No. 1 and No. 2 terminals.
There should be continuity when the brake pedal is pressed.
There should be no continuity when the brake pedal is released.

3. Check for continuity between the No. 3 and No. 4 terminals (with cruise control).
There should be no continuity when the brake pedal is pressed.
There should be continuity when the brake pedal is released.

4. If necessary, adjust or replace the switch, or adjust the pedal height.

The brake light indicator is lit up on the instrument cluster on the dashboard. Is it a sensor and how do I replace it?

Tonight I noticed that I have no brake lights at all. I do have marker lights. Turn signal. Back up. Etc I checked the fuse and looked for any disconnected wires, but didn't find anything. Could I have a bulb out that is causing them all not to work? Any help would be appreciated.

Start by looking at the switch on the brake pedal. If the brake lights are always on, I would suspect that you cruise control does not work either. The switch can be tested with an ohm meter.
