Have not been able to get the reverse light working on a AU ute-colunm shift auto,have changed both the globe and fuse,is the switch on the box a common problem with these?
I haven't had alot of experience with AU. Sort of went X Series E Series skipped over AU to B Series.

do you have power going in, then outgoing

Bridge reverse switch wires together and see if reverse lights work if so change switch

Will try that tommoz,thanks mate
