4 wheel drive is vacuum activated. Check vac motor 1st as it is probably the reason for it not engaging. I had a 88 cherokee w/ bad vac motor which caused exact problem you describe.

How do i check the front axle vacuum selonoid on a 2002 jeep wrangler


02 , just sold mine, best car ever. had, of many.

how do you know that.?

and what are the tires, touching, (dirt, snow,ice, grass , pavement)

what?

this car has part time 4wd, it is not AWD

its not a Grand cheerokee with AWD.

engaging 4wd on ice free pavement is wrong.

http://www.rubicon-trail.com/4WD101/driveline-bind.html



and my fsm states.

read the operators guide in the glove box, it will say....

"2WD is intended to be driven on normal street and highway conditions, such as HARD surfaced roads."

Then

"4H & 4L positions are intended for loose slippery road surfaces only and not intended for normal driving" (They assume paved streets are normal.)

"Driving in 4H or 4L positions on hard surfaces roads, will cause, increased tire wear, and damage to the drive line components."

Unqual tire sizes, will do the same damage. "circumference mismatched"

Last: "do not attmpet to make a shift, while only the front or rear wheels are spinning" No transfer case synchronizer exists and damage will result."

How do I turn 4wd on?


    • 1 Start your Dodge truck's engine.
    • 2 Turn the electronic transfer case from "2WD" to "4WD Lock" to engage the high range 4WD, if the dodge truck is equipped with an electronic transfer case; otherwise, shift the transfer case lever from "2H" to "4H." The electronic transfer case is located on the instrument panel and is marked with "2WD," "4WD Lock" and 4WD Low." The lever-equipped transfer case is located to the right of your leg and is marked with "2H," "4H" and "4L."
    • 3 Shift the transmission into "Neutral" while the vehicle is either stopped or rolling at 2 to 3 mph to begin engaging in the low range 4WD. Turn the electronic transfer case to "4WD Low," if the Dodge truck is equipped with an electronic transfer case; otherwise, shift the transfer case lever from "2H" or "4H" to "4L."
    Tips & Warnings
    • Indicator lights will come on and alert you that your vehicle is in either the high or low range of 4WD.
    • Do not engage in the low range of 4WD drive if the transmission is in gear; you must shift to "Neutral" first.
    • Many Dodge trucks allow you to shift from 2-wheel drive to the high range of 4WD at up to 55 mph--consult your truck's manual to ensure that this is possible. Do not exceed 55 mph while engaged in the high range of 4WD. Do not exceed 25 mph while engaged in the low range of 4WD.
    • Do not engage in 4WD unless you are on slipper or rocky roads.

Transfer case shifter is locked up in 2H on 4x4 montero sport 2002


Mine did the same thing so I removed the center console and then the boot around transfer case shifter and the shifter it self.
This is when I discovered a broken linkage that had wedged itself between the 4L & 4H shafts in the transfer case. I removed the broken parts and reassembled and it will shift between 2H & 4H but not 4L until the broken plastic linkage is replaced. Found your post while lookin for the replacement part so I thought I would try to help. Good Luck

98 expedition xlt wont engage in 4h or 4l. the awfs light is on when switch in that position, none of the others do (eg. 4H or 4L) the vehicle has not been in 4wd in a few months. last time 2low engaged...


one the transfer case there is a motor on the back side of the transfer case. most of the time that goes bad. if you don't have a trouble shooting guide with a wiring diagram, best to have a mech have a look at it. most of the time they rust and stick if not used a few times a year. best of luck.

1991 jeep 4wd fuse


Check transfer case wiring, possible loose wiring/open circuit. If your other lights in dashboard work such brake light, seat belt lights, engine light than it is not a fuse. raise all for tires from the ground and engage the four wheel drive remember to have in neutral and put in gear either 4L or 4H and see if the wheels in front move.

2002 4Runner - 4 wheel drive indicator won't go off


When the transfer case is not engaged for extended periods of time, the motor inside for the 4WD sticks. Try this: Raise the vehicle on a hoist, and do some tapping on the case while switching the 4WD indicator. Sometimes, this will free up the contacts inside the 4WD shift motor.

Hope this helps. Thank you for choosing FixYa for assistance.

92 full size blazer shifts into 4 high and low and won't engage


I have a 93 full size blazer and might be able to help. First you need to ensure that your are actually not engaging the hubs. To do this, shift into 4H or 4L and try to turn very sharply. If it is difficult to move forward with the wheel turned all the way, you are probably in 4WD and the indicator light may be out.

If the truck drives as it does in 2H, your front diff is not engaging. If this is the case, there is a thermostatically engaged actuator that may have failed. These fail occasionally and can be purchased at most auto part stores or at the dealership. Before you buy a new one, use a voltmemter to ensure that voltage is present at the actuator when you engage 4H or 4L.

I know several companies make a manual pull cable style activator that can replace the thermostatically engaged unit.
