MN wont go into 4wd, no lights on dash.

Hi guys I've got a GLX ute I use for work that has probably never been put into 4wd in its life, the other day I decided to try it in 4x4 but nothing happened. The lever moves into 4hi and 4 lo easily but I get no dash lights and the car doesn't feel like it's in 4wd (no heavy steering etc) however, low range seems to work ok, but only 2wd and with no lights on the dash.

Any easy fixes for this one? I searched and found the MLs had issues with front diff actuators, are these still and issue on the MNs?

Thanks.

Talking as a long term ml owner with super select but they have same front diff actuator as mn. Think mn has super select?. You can easily check if actuator is working by peeling back dust boot and pushing rod towards passenger side. Thats 4wd also default position when you start car till vacuum holds it in 2wd. If its not used much tends to bind. If hard have front wheels in air and slowly turn passenger wheel. If its in no mans land ie not engaging I dont think you will get the lights on dash including orange one when transfer case is locked. The past issue with ml was mostly due to the actuator been hit from under and moved a bit on mounts so would no push the rod in far enough. It only has to go a short way. Another cause was hose coming off and getting full of crud. Replacements even non oem copy now on ebay for cheap. This is worth trying as in my experience is far more common then broken/bad wire etc.

All sorted, actuator just needed a little exercising, hasn't been used for while in 4WD.
