The brake light above the rear window is on and it will not go out. Break light are off but that extra back light on top stays on.

I tried stepping on the brakes. Open and closed the rear door.

I don't know what else to do?

Don't really want to go the the dealer with this but I may have to if it doesn't go away.

Anyone ever experience this?

Thanks

 

sounds like a fuse.

 

I think in these ML's there is a computer box by the rear hatch called a "SAM". From what I have read in the forum, if this gets wet from a overactive car wash, bad hatch seal etc. then weird things happen. Let the warranty do the job, and hope that your tech doesn't destroy anything else in the process.

 

I did wash the car twice this weekend. Maybe got Sam a little wet.

I hate bringing the car in because of the reason you mentioned. I have a trust issue with the dealership and try to avoid going there unless it's mandatory.

I planned on bringing it in for an A service next month.

Think it will be alright till then or should I bring it right away?

 

If a fuse is bad wouldn't something NOT work?

I'm not trying to be a wise guy, just ignorant.

Anyhow, where's the fuse box?

Thanks

 

GO TO THE DEALER man. This is not something that can wait.

 

He is right- don't think, go to the dealership. If its SAM you can end up in the middle of the trip with opening/closing trunk, locking/unlocking doors like it happened to me. See 'haunted mercedes' thread I posted here couple monthes ago. And good luck! It is covered under warranty.

 

The light finally went out this morning but I went ahead and booked an appointment for Saturday anyhow.

I am just about due for my first A service so I'll get them both done this weekend.

Just hope they don't screw anything else up.

 

it your fog light.
