my boss has an s500 1999 model i assume.


Problem, her gauge cluster stops working, and brakes lights donot come on.

what i have found out so far is that on her fuse block under the hood she is blowing number 10 wich is a 15 amp fuse.

number 10 controls : gauge and brake lights.
apparently when she hits the brakes the fuse blows.

soo obviously replacing the fuses isnt getting us anywhere, its the weekend and the earliest she can get into the shop is on monday,

ive checked the bulbs and they all seem to be working,

ironically this is an off an on problem, like a month ago this happend and we swapped the fuse and its been fine up until now and its doing the same thing,

any ideas would be great.

Check the wiring going to the third brake light at the trunk lid hinge.

ding

that turned out to be the problem, MB even warrantied it !

It can also be corrosion/water in the rear light clusters which is blowing the fuses during wet and damp weather.

i guess you didnt read what i stated above.

i stated above that it turned out to be the wire on the hinge, it somehow got cut, probably from being opened and closed alot, the dealer warrantied the repair and there is no longer a problem,

when the fuses were blowing in the past the weather wasnt wet nor damp, i live in texas, aka inferno of hell

thanks anyways though
