12V Power Outlet Problem

My 2005 230K rear 12V Power Outlet has no power?? Checked the connections on the back of the outlet, checked the fuse (#12 rear trunk), both ok. Noticed when I placed the circuit probe on the #12 fuse connection it has no power (both with Key in #1 & #2 position). Is there another fuse? Any one have any ideas? Thanks

My advice to you is check ALL the fuses. Might sound a little crazy but in the past I have come across similar problems on vehicles, the fuse is ok but another fuse on a completely different row is dead and when replaced, voila, all is fixed and well. Even though the vehicles fuse map says the actual fuse for that component is completely different.

Just a suggestion from experience, worth a shot

Yea, I concur. If you have a spare for that fuse slot, it wouldn't hurt just replacing it anyways, just to be safe.

Thanks for the input, I look at every fuse and replaced #12 with no luck. I have to go to the dealership anyways as today the sunroof switch stop working properly as the auto open no longer works. I have a few months remaining on the warranty and will make good use of it. Thanks again
