Hi,

I need a little bit of help. My heater blower stopped working today on my '94 E280 and I looked straight away at the fuses and it had gone - easy fix I thought. On closer inspection the bottom end of the fuse had melted at some point so I had to get it out with small pliers.
I could then see that the metal cup it sits in had also got hot an it had 'sunk' and got covered in the black plastic of the surround it sits in - thus the new fuse couldn't make contact.
As a temp fix I have managed to drill of the melted plastic so there is a contact for the lower end of the fuse to meet.

Now the help bit: Can someone suggest a reason why this would have got so hot?

Can someone help with a part number for the black plastic fuse tray that the fuses sit in and the wires screw to underneath (this is seperate from the box).

Thanks in anticipation.
Toby
