I was doing some extensive yard demo this weekend and pulled up 2 sega palms. One of the palms was rather large so I put the truck in 4x4L, got the damn thing out the ground. The control on the dash stays lit on the 4L option, I can switch it to other options such as auto or 2 wheel drive and they light up and blink but it never gets out of 4L. In addition the traction control idiot light stays on as well.
The truck is normal other than that. TIA.

update - unhooked the battery as suggested and the unit switched from 4L to 2wd. I tested it both ways and unit switched while in park or neutral. thanks

Either the switch in the dash or the actuator (encoder motor in the transfere case) is bad.

Encoder motor retails for about $460 and switch in the dash is about $80

Had it happen on my 2012. I did forward, reverse, moved the switch a few times. Nothing. Disconnected the battery, let it set for an hour, repeated and it returned to 2WD

unhook attery cable, then turn key to start position and hold for thirty seconds. That clears the computer. Then reattach cable and see if it resets.

the switch in the dash for my truck went out when stuck in 4H, ordered a new switch, from wal mart actually, and threw it in, worked like a charm

Same thing happened to my truck. Believe it was the switch was bad. Got a new one from Amazon.

It's usually the switch in the dash that goes bad mine had the same problem. You can order the part for about $50 online.

Floorboard that piece of shite in drive, then slam it in park. That Should fix you right up.
