I have an F78 and the green 4Hi does not work, not sure what could be causing this, fuse relay or Trans Case etc.

Any ideas

ours has never worked.... doesnt stop the front wheels driving so ive never bothered to find out why

Go under the drivers side of

Go under the drivers side of the vehicle and you will see the front of the transfer case sticking out if you look rearwards.

On this protruding section is a switch, fire up the engine and check for power in, operate the transfer case and check for power out.
If you have power in, fine, but no power out then it is the switch, if you have power out it is the wiring from the switch to bulb, or the bulb itself.

If you have no power to the switch then it is wiring or a fuse.
