Hi yes the only fuse power supply I v Co puke find was under bonnet. There were no relays marked for 4wd in side panel drivers door or under bonnet.

Just gone through this with my Grand Cherokee.
Grab a good OBD reader and a good scanning program, heaps out there, it will pinpoint it.
I ended up with a OBDLink and the AlfaOBD (works very well with Jeep) software which can communicate with all modules in the car, pinpointed it within a few minutes.

Pull the electrical plug off the transfer box. Give it a good squirt of WD40. Give any male connections a bit of a rub with wet & dry. See if that solves your issue

Interesting it's not chucking any errors, did you try a decent scanner that can access all modules?
Try all fuses and relays.

I'd pull and inspect all fuses.
The handbooks are usually a bit rubbish and you can find components getting power through circuits that can appear quite random.
My rear diff lock didn't work and the running off the circuit for the radio or something equally unrelated, that was from the factory too.

Hi all got two different engine scanners on it from a workshop. One Milwaukee the other was his previous unit. Could not get any errors from them . Did see a video on YouTube about no power but don’t know how to contact the video poster to get information. Any ideas ? Thanks for your help with this it is greatly appreciated.
