my 166 3l v6 manual has developed an electrical fault, initial symptom was that the indicators worked on one side, but when the other side was switched on both sides worked at once, until the fuse failed there was a strong smell of burning plastic, the hazard light switch also burnt out. It's currently in the workshop, they have removed the ICS, drivers airbag, instruments etc. to get at the switch and lots of the wiring, they are saying that they can't find the short circuit/burnt out wiring without completely removing the dash so that they can see where the loom(s) pass through the bulkhead, vast amounts of work and expense. Anybody out there had experience with a problem of this sort, (they have used a camera to look for the fault) any info such as most likely place and which colours of the wiring loom to trace through would be most welcome as the car is destined for the scrap heap unless it can be traced more easily. Thanks in advance for your help.
