Got a 4wd camper with manual hubs and switch on dash. Turned it on in snow but now will not disengage despite turning button off. Tried reversing up curb and switching on/off but not working.

HELP

Can you disengage the hubs?

I think the switch is vacuum operated on the transfer box?

Unlocked hubs but no difference; 4wd light on dash stays on whether swith on or off. I think I can hear solinoid switching. Tried reversing in car park, bumping off kerbs, reverse/forward/reverse, etc. will try and jack up rear wheel tomorrow and maybe give gearbox a slap with a stick or something!

Fixed it. Vacuum Valve Assembly. There are two vacuum solinoid valves, one to engage 4wd, the other to disengage. Needless to say it was the disengage that was gone. fiddled with similar items off ebay before buying to proper part.
