Brake lights

There might be an easy way to narrow it down.

The circuit for the brake lights goes from the brake pedal directly to the high brake light. To get the tail lights to work, the circuit runs through the multi-function switch.

Do you have a high/rear window brake light?

If you do, and it works OK, then you might have a problem with the multi-function switch.

If the high brake light does not work, then focus on the brake light switch on the brake pedal, or the fuse.

Try replacing the fuse. It is very rare, but there could be a problem where the fuse looks good, but under load, it could be a problem.

Find the fuse location by looking in your owners manual.

Look under the dash and find the switch attached to the brake pedal. Look for loose connections or wires that might be pinched or stretched when the pedal is depressed.

If you have brake lights work and then not, chances are it is not a fuse. I would how ever suspect the brake light switch. They don't cost much. You can use a test light to check it should have power on one side and when you step on the peadle the other side should be hot. If you loose power when pushing it down more replace the switch. 8) NOS
