instrument cluster will not indicate when in 4WD

Hi I have a 2004 Prado 120 GXL Auto. I have not had it off road since passing it onto the wife. I took it up the beach recently and engaged 4WD, it seemed to be engaging fine but the indicating lights on the cluster did not change. I just had the 130,000Km service and asked Toyota to check it out, they ran diagnostics and informed me that the bulbs are fine and No errors recorded. They said they would need the car to further investigation, I am reluctant to spend a heap of money to find the cause given that 4WD mode is working as it should. I started the car on the weekend and engaged Hi and Lo range repeadly with the selector and got not the Hi -Lo indicator to light but the orange centre dif lock indicatorto flash intermitently.

I feel it may be a faulting 4WD mode sensor on the top of the transfer case, but to remove it requires dropping the gearbox. Has anyone had experience with this or a similar problem?

Regards Walt

Certainly sounds like a dicky switch or possibly damaged wire? Need to have a good poke around under there to check.

I've done just that, very tight up the top of transfer case. Wiring looks OK, I've visually traced back as far as possible. I cannot remove the sensor/switch without lowering the transfer case and gearbox to allow access. I'll try to unplug at the nearest join and use a meter to check if it changes state when engaging the lever!

I had the ame thing, the toyota boys pull off the wires spray them with some WD40 or something put them back on and all was good, worth trying.
Their is also some threads about this already, have a play with the search.

I think there was another post about the same issu maybe a month ago. I seem to recall the issue was a loose connection near the transfer gear selector.

EDIT: Had a quick look and found this:
should there be a 4x4 engaged dash warning light?. First post was 21st September
