1999 W210 horn and sunroof stop working at same time
 

Looked on the forums for help on this, but couldn't find anything. I have a 1999 E300 Turbodiesel W210. In the morning when I first start the car, the horn and sunroof work fine, although the horn is a bit anemic. After a few minutes of driving, the horn and sunroof stop working. I have checked fuse #41, which is indicated for both, and it is fine. Wondering if disconnecting and reconnecting the battery would do the trick. Any help would be greatly appreciated.

Thanks in advance

If you look at the fuse guide, there will be a 41 and then there are a couple numbers in (...). Look under the back seat, next to the battery and those fuses will be there in the other fuse block.

Check to make sure there's no corrosion or any other thing that might be causing trouble.

Yes I have checked fuse under the seat...all seems ok
