Cayenne Interior lights stopped working

[jppwalsh]

On a 2006 Cayenne, the Front interior lights, both vanity Sun Visor lights and the 2 back seat interior lights do not work. The issue began when the drivers side Sun Visor broke.

I have since replaced the Drivers Side Sun Visor but the light still do not work.

As a note, the interior light over the trunk work and the red lights in the doors work.

Any help Appreciated.

Start by checking the fuses

Also, sometimes when there is a short (like with your visor) it corrupts the memory in the control unit. In these cases the control unit needs to be re-programmed with a Porsche PIWIS tester.

Thanks Loren. I checked the only fuse that was labeled for the interior lights in my manual and it was good as when I removed it, the light over the trunk door went out.

There is only 1 fuse for the interior lights? My vehicle is a 2006 V6 Cayenne. I believe the fuse I removed was labeled 12 on the drivers side fuse location.

Pretty much the one fuse.

I am thinking "why are you asking this question about your Cayenne on the 996 Forum." But then I think I know, Because most of us 996 owners send a lot more time working on our cars than the Cayenne owners do.:clapping:

Problem Solved. It was a fuse that needed to be replaced, it was fuse no. 27 which according to my manual isn't used.

Thanks Again.

I’d like to bring this thread back from the dead, in hopes of finding some insight. 
 

Just like the OP, my dome light, vanity lights, and rear seat lights don’t work. 
I haven’t had the car long, so no sure if they ever have. 
I checked fuse 12 and it was good. If I pull it out, the other lights (foot well and cargo) go out. 
I found this thread and checked # 27. There was a blown fuse in there. 
I replaced it with a 10a. I saw the dome lights flash, and the fuse immediately popped. I put a 15a in, and same thing. I put a 20a in and heard another pop, but this time it was fuse #12 that blew. 
 

I unplugged the dome lights, but still have a dead short on #27. 
I have looked through countless wiring diagrams, but none list anything for #27 in the left side fuse box. 
 

Anyone ever see a listing for #27, or have any ideas what could be the issue?
