Does anyone have access to a 2004 Cayenne S wiring diagram?  My interior lights will not come on.  Fuse 12 was blown, and it blew again immediately upon replacement.  Now it seems to not have blown but no lights come on.  I'm trying to find the branches that come off of fuse 12 in the drivers side dashboard.

Got it.  Thank you.  Apparently the melted center contact is a good starting point.  But still doesn't seem to make sense for all the other lights too.  Maybe Miss Piggy just wants to spend some quality time with me.  Haha.

I have the same problem. I got it with this problem. So I had pulled the fuse the other day and saw it was burnt. I bought some new ones and the first time I plugged the new one in, the lights worked after. I already had the key in but it was not on (it also does not recognize when the drivers side door is on). I can not remember if the lights came on right away when I put the fuse in or if i had to turn the key. They worked just fine while I was doing a few things in the car and then I took the key out and put it back in and the fuse blew instantly. I just checked the vanity mirror real quick on the passenger side, just in case, and there seems to be no light on it. 


I went back to look at it tonight and put the key in and put a fuse in and it sparked and instantly blew. I tried turning everything off and doing it but blew a few fuses and ran out. 


Any help or guidance with this?  Also, one other thing I noticed while the lights were working. They turned off and I had them come back on a few times and I noticed the rear passenger reading light came on dim and flickering. I then touched/slid the overhead map light switch in the front middle there, and the rear light came to full power. I am wondering if that switch in there is having the melting problem everyone has reported. I inquired to sunset about the repair kit. 


Any help or tips or ideas would be greatly appreciated.
