Center diff lock inoperative

[rmurphy5]

Hi guys, my centre diff has stopped working. It is definitely not engaging rather than the switch being faulty. Which pins on the plug to it power it? I hear the relay click in the passenger footwell but no noise from the actuator at all. It did work well until recently. I just want to check the loom before I take it off.

Thanks!

The diff. fuse powers only the actuator motor, not the relay. So if you have a footwell click, the diff fuse can still be blown.
You have listed your 100 as 2003 -- There is a difference between production date before and after august 2003 -- It's the production month which decides which diagram to look at, but for this issue, I can't see much difference.
