Hello,

I have a 2000 xkr coupe and driving to work I was told my main brake lights are out and the third light is the only one that works. I confirmed this. I did a search on this site and it looks like it may be the brake switch, but is the third light affected by this? I just want to fix the problem accuratley. I did not have a rear brake warning failure. I've had other rear light grounding issues in the past, but that has been corrected. Also, I tried look at the wiring diagrams but the work computers block the weblinks. I'm using my phone to post this message.

I appreciate the help! This is my daily driver and New Jersey will pull you over if you have a light that thinks it wants to go out.

I'd expect a failed Brake Switch to kill all the brake lights.

Here's the relevant graphic from the Electrical Guide as a JPG:

Looks like the "high mounted" light is on a different fuse to the two "normal" lights - top two fuses in the trunk fuse box. Might be worth looking here first.
Cheers,

I also remember reading some threads on tail light grounds, do a search on it and you will find many members had to 'improve' the grounding in this area, I'm not sure if it would affect just brakes or all lights or a mix ? Let us know what you find.

oops, reading too early I see u've visited the grounding issue, maybe just double check anyway

 

Thank you for the help! I looked at all fuses last night, nothing was blown, but I hope I missed it as it looks like it should be the 5 amp fuse they both share.

Thank you!
Jim

 

5a fuse was blown, all is good now.

Again, Thank you!

Jim,

Thanks for posting again with the explanation.

I've added 'RESOLVED' to your thread title to help others searching for a solution to this issue in future.
