Hi Folks. I've got an issue when using a trailer. The RH trailer aindicator is on permanently as soon as ignition is on. I've tried a bike rack and still the same. The indicators and hazards work normally. When trailer connected and hazards on all lights flash as expected apart from trailer RH. Turn ignition on and trailer RH indicator on permanently. Put hazards on and trailer RH on permanently rest of lights on truck normal operation.
I've disconnected plug behind RH wheelarch and tested supply side with multimeter. Power continuously on green white going to RH indicator on trailer.
I've added photos. Any ideas please?
