Location of fuses and relays on Mercedes Benz E Class All Models, years 2003 to 2008.
If you replace any fuses, make sure to replace it with the same color fuse. If there is an underlying problem you could overload the wires or even cause more serious problems to that circuit if you use a higher ampere fuse. Make sure the new fuse you are installing has the same color and ampere rating as the old one. If you install a new fuse at it blows shortly after you install it then you could have a short or a problem with that circuit and you need to get it diagnosed. When you replace fuses make sure your ignition is off.
You can get a lot of fusees for cheap on Amazon, like these ones here. Make sure to replace the fusees with the correct color and ampere rating.
You can get a box with lots of fuses on Amazon for about $10.
