Default Brake light issue: middle light works, side brake lights don't

Greetings All,

I am having an issue with my brake lights. Only the middle light on the hatch illuminates when I depress the brakes.

When I switch on the running lights, the primary filament in each of the lamps lights up but the brake filament won't illuminate when I depress the brake.

I checked the fuse(#8) and it is fine.

Also, I find it highly unlikely that the brake light filament in each of those lamps failed simultaneously.

Wiring harness kink or a faulty relay somewhere? (Or bad lamps...if only. )

Should be fairly easy to test.

Pull the working bulb out and put it in place of one of the ones not working. See if it continues to work (then bad bulbs) or not (then probably something electrical like wiring).

I'm not sure I follow you. Are you suggesting that the middle hatch lamp is the same as the combination lamps in the tail lights? Both of the combination lamps are having the same issue so switching one for the other doesn't seem likely to produce any new information.

I'm going to start looking for kinks...

The first thing to check would be the bulbs.

Sorry, misunderstood your first post.

Thought you meant only a part of the hatch break light was working.
