SOURCE: 2004 GMC Sierra 1500 4wd. Auto transfer case light issue

I have the same problem. It is intermittent and sometimes shows up with service transmission message. To get rid of it just put the truck in park, press the 2 high button and shift into drive while it is still flashing. I will worry about it more when it blows up. You can drive with the vehicle showing the solid neutral and it seems to make no difference. It has to be a wake up problem between the control modules. It only happens on start up.

About 45% of all transmission problems are due to a defective battery, its components and the charging system. Make sure you have the correct battery in the vehicle and inspect all items relating to the charging system and the battery. The vehicle should charge between 13,5 to 14.5 volts. The condition of the belts is part of this inspection. If all of this is A-ok then get a scanner and pull the codes in the PCM.
Remember once light is illuminated for a item that item no longer works. Once you've gotton to this point let me know and I'll walk you threw it. Hopefully its just a weak or incorrect battery or something along those lines. Good luck and keep me posted

SOURCE: my service 4wd light appeared on my dash and my 4wd is not workin

Transfer case engages/disengages via a vacuum line. If the vacuum line is cracked, often by age and cold weather, it has to be replaced to allow a good vacuum pressure.

Sounds as if the transfer case control module has gone bad and grounded the circuit to the 4 low actuator. The module is located behind the headlight switch in the dash. You could try tapping the actuator on the transfer case lightly with a hammer to see if it releases.

There is no such thing as a reset, if the light stays on a fault exists in the 4X4 control system, the control module has sensed that and turned the light on to alert you to the problem. It is likely that the power transfer case actuator motor is the problem or the wiring to it.

transfer case, both are electronically shifted by the TCCM (Transfer Case Control Module)...so you may have a selector switch (dash) or mode sensor issue, that needs replacing on the encoder motor in the transfer case.
