i have a 2002 audi a4 b6, a mechanic has changed the drivers door wiring loom. He used the wrong loom and when he plugged it in the windows, mirrors, interior light, door alarm, door light stopped working. Repaired the old loom and refitted and still nothing came back on. Could it be a main fuse that has been blown. Where abouts are the main fuses

Please help asap

 

if your mechanic did it let him find it! And let him pay for it while your at it!
