Third Brake Light - Cayenne S – 2008

Recommended Posts

I’m new to Renntech…just joined yesterday!!  Long time Porsche owner.   I really like what I’m seeing!!  I have a general question I’m hoping someone can help me with.  I know I am not the most computer literate, but can’t find how to search the forums for a specific topic.  I would appreciate any help!  I also have a question on my Cayenne that has probably been discussed previously…but since I haven’t been able to figure out how to search the forums….well you see the problem.

My third brake light is not working.  The other 2 are working fine.  I removed the upper part of the rear spoiler to expose the LED light.  I wanted to make sure I was getting current to the light before replacing the light so I removed the connector and put a voltmeter on the plug-in connector.  I am not getting voltage.  So I went to the manual to locate the fuse…and there is no reference to which fuse controls this light.  I know very little about LED lights other than the fact that they draw very little current.  Hopefully someone can help!!  I have 2 questions;

                1 – what fuse controls the third brake light?

                2 - what is the correct way to test the connector to determine if I have current to the light?

Thanks in advance for your help!!
