2004 Chevy Silverado Z71 stuck in 4 low

My truck has had the service 4WD light on for some time now, I haven't been able to shift into 4 wd, but the other day I got stuck and was able to shift into 4 low but now cannot get it to shift back. I have tried the disconnecting the battery trick and that didn't do it. Any suggestions.

That was a good suggestion by Molson. Also, if you have been doing a lot of heavy hauling, have them check the strainer, which could be a problem as well.

I have a few99 gmt jimmy with the automatic 4x4 buttons. I can't get it out of 4x4. Please help


Well from experience 99%. Of the time its not the actuator if it shifts into 4 lo and back to 4 hi. The book really sucks at this diagnosis. And if lights on buttons blink for 2 hi for a bit then stay in 4wd then u have to listen very carefully. When shifting from 4 hi. To 4 low the whine or growling noise from motor is heard. If, when shifting from 4 hi to 2wd this motor noise is heard, then actoator or wiring is the issue. If the time while 2wd light is blinking, ie: its trying to shift, no noise from motor or actuator is heard, then shift module has a burnt output. Now. Before replacing any of the components, if you have a schematic of this system, you would be confused on how any of it elworks even if you are a seasoned professional. I wouldn\'t bother 2 much with it as long as you theory inspect Evey millimeter of all the wires from actuator connector (on transfercase) to where it goes through metal and enters occupant compartment. If all wires look good. Lights in all 3, or 4 if u were lucky in neutral which means error, of the lights work, and if requested position is depressed on switch and motor tries to turn or does and clynks are heard , then actuator position switch is stuck and actuator is needing replaced, as not a serviceable assesembly, and I haven\'t had the ability to tear one apart. But if all lights work and when the selected switch button , example 4 WD, 2 WD or 4 lo, and no motor noise like heard when other shift works, them module is to blame. Now, I am a master mechanic with most experience at a gm dealership, I have fought with this system multiple times, and once I employed this diagnosis it has never failed me again. And the stack of 4wd shift modules in my bottom toolbox dawyer. Most times if won\'t shit at all night be actuator but not likely, 95% of the time when this issue rolled through dealership, it took a module to fix it.

2008 Jeep Compass is stuck in 4 Wheel Drive with exclamation point by the 4 WD indicator...


If you are driving on the highway in 4wd drive the poise may be from the tyres trying to slip and equalise the drive line torque that is building up . Rule of thumb for all 4 wd vehicles is to restrict 4wd to loose surfaces (gravel-snow-ice -grass- mud --any surface that allows the tyres to slip) to relieve the torque wind up.

I have a 2002 silverado 4x4 with a manual t/c shift. After putting it into 4 wd it will not disengage back into 2 wd.


WHAT SURFACE are you driving on,...????? ICE , pavement?
part time, full time or AWD? which is it.
Autotack????
open diffs?
some AWD have a center diff, lock , is that on? (never on pavemnt)


a chevy Jeep Grand cherokee??????
is this a 4wd question?
are you driving on pavement , ICE, snow or dirt.
my wild guess, is this is Cebby. and is not a Jeep
and is PART TIME 4WD and is not AWD
if you drive on pavement that is not covered in ice or snow
that is wrong, the manual explains that.
part time 4wd only works on ice or dirt.
more simply,. 1 tire must slip, that is be on something like ICE or dirt .
Part time 4wd has no center differentail
and if you drive on pavement (dry) it will windup the drive line
and something breaks.
so REpost what you are driving on , the world is complex
dirt,sand,snow, granite, ice, mud, ?

im guessing, here is trac-lock. discussion....
http://www.fullsizechevy.com/forum/general-discussion/technical-maintenance/504267-2002-silverado-z71-4x4-not-working.html

here are the options, then
quote:
The only 4WD options were either the base option with a manual 4WD shifter in the floor OR the more expensive pushbutton version in the dash. The pushbutton version also provides full-time 4WD capability, called AutoTrac. Whether the rear differential is Limited Slip or not is a separate option. Limited Slip is not available in the front axle.
end quote.
the base version is not for Dry pavement, and if you make that
mistake, the gears will be very hard to impossible to UN SHIFT
due to driveline gross wind up, just like any jeep, 4wd.
RTM.

Have 2005 chevy silverado stuck in 4wd-lo will not shift to 2wd all lights are out checked fuses are fine


If all the lights are out then the 4wd switch is bad but,if it won't come out of 4wd-low then the 4wd actuator is bad or stuck.The 4wd actuator is what engages the differential from 2wd to 4wd.HOPE THIS HELPS!!!
