4x4 switch not working

When I turn my switch on to turn on four wheel it doesn't come on neither does the four wheel drive. Any way to check the switch worked month ago for my grandson. I did run it thru the carwash that that did an under body wash. Could that have messed something up

Check fuse 19 and 111 in the fuse block under the dash.

Check the wires/plugs/connections under the truck into the 4wd shifter motor.

Also, Check for a vacuum leak in the lines between the hubs and the intake manifold or vacuum pump.

If you don’t see the dash light up within a few seconds of flipping the switch, then as others have suggested electrical or the actuator on the transfer case.
