The switch on the transfer case is stuck internally. Replace the switch.

I have a 93 jeep Cherokee, it will move in 4wh and in 4wl but will not go back into 2wd?


Hello guy
try posting what 4wd system you have,? first.
command trac or select track, (the latter is full time)
part time or the full time system,
we cant guess it....
read the operators guide first, if a part time system only
as i suspect, stop driving on dry pavement.
it's only for ice, or dirt. part time. part time is not a full time system.
Command-Trac
shifting to 4wd on dry (means no ice) pavement causes, drive line wind up! and the gears to lockup. (see steering get tight in turns?> and is dangerous to drive it like this , you, me and the box)
posted here 100s of times.

the non grand Cherokee. early

had these choices
  • 1987-2001: New Process NP231 Command-Trac, part-time only, 2.72:1 ratio with low range
NP231 has the following settings: 2HI, 4HI, N, 4LO
  • 1987-2001: New Process NP242 Selec-Trac, full-time or part-time, 2.72:1 ratio with low range
NP242 has the following settings: 2HI, 4 full-time, 4 part-time, N, 4LO


as you can see you need to first know, what NP box you have or
photo your shift lever for 4wd, an post it and we tell you.

more facts, on select trac. (totally unlike command trac)
Selec-Trac locking hub is used on 4WD Cherokee. Selec-Trac
utilizes a non-disconnect front axle. Engagement of 2WD or 4WD is
accomplished at transfer case by means of mechanical shift linkage.
System allows full or part time 4WD. Selec-Trac can be shifted into
2WD or 4WD modes from inside the vehicle at any speed.
unquote
next from the service manual,
4WD TO 2WD
1) Place mode select switch in 2WD position. Transfer case
should shift to 2WD and not allow shifting into 4WD or LO range. Axle
should shift after transfer case shifts.
2) To determine if front axle has completed a shift out of
4WD into 2WD, position mode select switch back to 4WD position while
operating vehicle at slow speed. If vehicle shifts into 2WD, axle will
ratchet. If shift is not completed, transfer case will shift into 4WD
and hissing sound will come from mode select switch.
end quote.

if unsure read the FSM book its free.
shows you both systems and how to diagnose it.

in the box, click Cherokee,,then click 1993, and behold.
the real deal.

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.

Having activation problems. How exactly do you activate the 4 wheel drive on a 99 Jeep Cherokee?


Just pull the control lever one notch rearward. first position is 2wd, next is "part time 4wd". after that is neutral (only used when your vehicle is being towed) and last is 4 low, only used when pulling heavy loads at low speeds on slippery surfaces. Best to engage 4wd while rolling at under 30mph. If dash light remains on after shifting back to 2wd, usually backing up about twenty feet or so will disengage it.
If doing what I said does not get you into 4wd, then you need to have someone qualified look at it to make sure the transfer case, front differential and both front axles are in good condition.

sounds like it might be an encoder moter, but the best thing you can do is take it to a good transmission shop so they can hook up their reader and find out for sure

05 Suburban Will not go bcak into 2 wheel drive.


I have had similar problems with my burb also. Mine would shift into 4wd at any time, then not go back to 2wd. I have taken it to the dealer multiple times. the first time I was told in not so many words that I was crazy and it worked fine for them. the second time they experienced it and said it was a bad sensor and they replaced it and it was good for about a year. Now the warenty has expired and it is acting up again, can't wait to here what they say this time. Curse GM, they should have been allowed to fail, all they do is produce crappy products. The only way I would buy another GM product is if they start producing Hondas.
