Hi
We have recently purchased a Mercedes vario 814d and have a problem with the drivers tail light. We changed the bulb and every time we turn the lights on it blows the fuse we have tried:
New fuses
New bulbs
guessing the problem is the wire is shorting out somewhere between the fuse box and the light but can't find where or the solution. Does anyone else out there have any electrical expertise with an 814d

Thank you in advance
Hannah
