I did a search and did not find anything...so,

The 4wheel drive light came on today and I was wondering if there was anything that I could myself to fix/check the problem. Also, the display which shows you which wheels are engauged is not there anymore, and if I try to put the truck into 4hi/low it does not work.

If any malfunction occurs in the 4WD system
when the key switch is ON, the warning light will
either remain illuminated or blink.

If the 4WD warning light comes on, the 4WD
shift indicator light goes out.

For all mode 4WD vehicles, high-temperature
transfer case oil makes the warning light blink
rapidly (about twice per second). If the warning
light blinks rapidly during operation, stop the vehicle
in a safe place immediately. Then if the light
goes off after a while, you can continue driving.

A large difference between the diameters of front
and rear wheels will make the warning light blink
slowly (about once per two seconds). Change
the 4WD shift switch into 2WD and do not drive
fast.

If the warning light comes on or blinks
slowly during operation or rapidly after
stopping the vehicle for a while, have
your vehicle checked by a NISSAN
dealer as soon as possible.

Shifting between 4H and 4LO is not
recommended when the 4WD warning
light turns on.

When the warning light comes on, the
2WD mode may be engaged even if the
4WD shift switch is in AUTO or 4H. Be
especially careful when driving. If corresponding
parts are malfunctioning, the
4WD mode will not be engaged even if
the 4WD shift switch is shifted.

Do not drive the vehicle in the 4H or 4LO
position on dry hard surface roads. Driving
on dry, hard surfaces in 4H or 4LO
may cause unnecessary noise, tire wear
and increased fuel consumption.

If the 4WD warning light turns on when
you are driving on dry hard surface roads:
– in the AUTO or 4H position, shift the
4WD shift switch to 2WD.
– in the 4LO position for all mode 4WD
vehicles, stop the vehicle and shift
the transmission selector to the N
position and shift the 4WD shift
switch to 2WD.
– in the 4LO position for part time 4WD
vehicles, stop the vehicle and shift
the transmission selector to the N
position with the brake pedal depressed
and shift the 4WD shift
switch to 2WD.

If the warning light is still on after the
above operation, have your vehicle
checked by a NISSAN dealer as soon as
possible.

The transfer case may be damaged if
you continue driving with the warning
light blinking rapidly.

I am not driving it in 4hi or 4lo or have not in months. The lifht just simply came on and has stayed on today. I mearly tried to switch the switch from auto to 4hi to see if something would change.

This is why manual locking hubs are more reliable and less prone to problems like this.
