Did you happen to look at the voltage gauge when all of this happened. Was it reading less than 12 volts?
I think a good start would be to check the alternator to see if it is charging. With the engine running you should see more than 14 volts. If you see 12 or less volts the alternator is no longer charging. Once the other vehicle systems see low voltage they start to shut down and turn on indicators.
All of the things you mentioned happening are fairly consistant with low battery voltage.

Have a repair shop scan the vehicle for codes
& diagnose them
I fail to see,if your here,what you can do, without
professional tools & knowledge needed to use them
How about check the charging system for charging voltage with a volt meter? People post here for help! they already now know they can bring it to a shop to have it diagnosed. If you not willing to help, Teddy, than why post?

service it like you would the truck engine it will have to be reset by the book almost like the truck i had that same problem
SOURCE: Message center: "4WD SERVICE " LITe on.
sound like a relay problem under your hood is a fuse box with relays and fuses check them that should be your problem....
SOURCE: electrical ?
probally need to check engine groundwires. clean all terminals. battery may have loose terminal.
SOURCE: changed the actuator on my 2000 sierra but the service 4wd light
Have you reset the computer?
If not,you need to diconnect the battery for a few minutes.
Please rate this solution.
SOURCE: Is there a inline fuse for dash gauges and where is it
try cahnging the relays under the hood those are the square black fuses in the fuse box
Whenever
this warning light or any other stays on in the dash it is indicating
that the systems control module (or the system sensor in the case of
lights like low oil pressure, door open indicators etc.) has detected
a fault, it then disables the system (this applies to ABS,TCS, TCM,
SRS, TPMS and BCM faults and others) as long as the light is on. You
must now have the dealer hook up a special electronic diagnostic tool
and "scan" the system for the fault code that is stored for
the problem(s)
