This just happened to mine this morning. pcatudo is right on the money...I left in in 4Lo, turned it off, turned it back on, put it in Neutral and then turned the dial to 2WD. It clunked and transferred over.

I have a 02 Chevy Z71 1500. I locked it in 4lo and now my (service 4wd) light is on and the lights on my panel for my auto, 2wd, 4hi and 4lo don't work. Plus it will not come out of 4lo. Any answer's?


Okay the motor for the 4x4 got stuck in 4LOW, Can you accsess the 4x4 motor switch,at see if that will retract the motor and default to 2 wheel drive because the switch itself went bad and wont disengage. see if that will help if not youll just have to by pass the switch and trigger to its normal position make sure its in neutral also

How do i know when it is in 4x4 . where must the lever be for it not to be in 4x4. no the lever is has got 2lo, 2hi n 4lo and 4hi. when you drive where must the it be, and is there lights on the bash that...


Hi, 2hi is your normal driving selection, this is NOT in 4WD mode. Both 4lo and 4hi is for 4 wheel driving, 4lo is used in extreme conditions and will gear the vehicle down to a very slow speed with maximum traction at the wheels, 4hi is for general 4 wheel driving in rough terrain, if you have lights on the dash than it will come on when you change gears, hope this help

sounds like it's the motor is going bad or has a bad connection, try cleaning the connector if there isn't any gunk in the connector, check the manual see if there is a ohmn test you can run on the motor, if not i'd replace the motor.

How do I activate the 4 wheel drive for snow highway driving?


They didn't make Grand Cherokees in '86, so I assume you mean '96?

I'm also assuming it is indeed a 4x4 and not a two wheel drive...sorry, I have to ask!

All the V8's GC's were Quadra-Trac. Please confirm this with what is label on your shifter. If so, it should say "4Hi, N, and 4Lo".

The Quadra Trac system has a viscous coupling. Meaning, that when the rear wheels start to slip, it heats the coupling up, and engages the front wheels.

This system typically put about 95% of the power to the rear wheels, and only about 5% goes to the front during normal driving, so it's essentially in 2wd mode.

When you put the transmission shifter into neutral, and pull your transfer case down to 4lo, then you have all four wheels locked. Do not drive like this on dry pavement.

To answer your questions, the 4x4 should automatically engage when the rear wheels start to slip. It is a seamless transition and you really won't be able to tell.

If you're in real bad snow, then pull it down to 4lo. That'll lock all four wheels in and give you greatest traction.

Drive safe.
