TL777

I drive a 2006 C280 4matic. My car remote does not work (a few times it worked if i stand right next to the drivers side door) and the radio is shot. I checked most of the fuses. Fuse #8 keeps burning out when I go to replace. I heard a humming sound from the ceiling/dome lights (front). I thought about disconnecting the alarm horn from the front right passenger side wheel but I could not find it. Is it something with the antenna amplifier? Anyone have the same issue with a fix?

Thanks

I read in a thread it may be the alarm horn and tried to find it to disconnect. However, I did not see it in the front passenger wheel arch. I guess I will have to look again as I tried to find it without taking off the wheel. Is there a chance it could be located somewhere else?

Can I disconnect the alarm horn for the time being without doing a replace? Or will this potentially cause other failures?

Any recommendations for websites to purchase this part?

Thanks. It worked. I disconnected the alarm horn and replaced fuse #8.

The problem you have can be fixed by replacing the RF amplifier which is up in the rear headliner just forward of the rear window.Dealers will charge
approx. $1600 to do this repair.Check the 8 amp fuse in the trunk fusebox
first and if its blown visit a junkyard to get a good amp, install it/fuse and
everything will work just fine.......nitrame
