Haven't found my specific problem on here.All right indicators don't work,fault code b1007 direction lamp incorrect?
Hazard light switch doesn't operate right indicators,neither does the indicator stalk.I've replaced all bulbs to rule that out.Indicator light on dash flashes quickly when right indicators selected.
At the front right indicator bulb i used a power probe and applied 12v to the bulb,it lit,which rules out the bulb and proves the earth is good.
I'd love to know which pink wire coming out of the bcm is the right indicators one.I'm expecting my test light to flash off and on when i find it,all pink wires i've tested at the bcm have showed a 'constant' 12v and not going on and off with the indicator pulse??Couple other pink wires didn't show a voltage at bcm,but as i said,i don't know which pink wire is one i'm after.
Just had a thought,the rear driver side light cluster has the long brass coloured threaded bolt broken off,please dont tell me this is the earth for the cluster?Or is it just to help mounting the cluster?

No flasher relay on these unfortunately,they are BCM controlled with a pulse width modulated signal to the indicators,wish to hell it had relays! ;-)
 
Finally,well think i've at least discovered the 'result' of whatever has gone wrong.Found the output wires on the BCM to the 'good' inicators on the passenger side,test light was flashing on and off like it should with the pulsed signal to the indicators,however,the pink wire supplying the bad side 'wasn't' lighting my test light!Plus,on cutting the wiring loom electrical tape back i discovered the pink wires plastic covering had melted!!!All the way up the wire!!
Unfortunately i think the indicator relay soldered onto the BCM circuit board has blown and melted my wire!
Not really something i wanted to discover on my first week of owning the car.
So i take it these relays aren't sold seperately,and i just have to buy a used bcm donor part?
 
Bought a donor board to take off the indicator relays and put them on my car.This was after watching someone do a similar thing on youtube.After turning on ignition after completing the job indicators on 'both' sides are now not working??and as an extra bonus the keys aren't recognised now lol,oh joy,after the grief of trying to get these two relays off too.
