MY 1998 GMC JIMMY 4WHEELDRIVE IS NOT GOING IN 4L OR 4H THE TRANSFERCASE IS WORKING BUT ITS NOT LOCKING IN

the samurai doesn't have 2L it has 2H.
there are 4 modes on the transfercase. 2H, 4H, N and 4L.
2H engages the rear wheels only while 4H and 4L engages all 4 wheels. N disengages all 4 wheels, useful for flat towing.

Yes the light should be on when it is in 4 wheel drive, either 4h or 4l, to engage it into 4h you need to lock the hubs then select 4h while moving. Now if u want to put it into 4L you need to first stop the truck, put it into neutral and then select 4L

Have it checked by a transmission shop.

Possible actuator motor issue have it tested.

Hi - Here is instruction how to do.

From N to 4H

Stop the vehicle completely, place the

transmission in "N" (Neutral) and depress

the brake pedal and the clutch pedal fully

(if equipped), then push in and turn the

switch to shift into "4H".

From 4H to 4H LOCK

You can operate the transfer switch either

when the vehicle is stopped or while the

vehicle is moving.

Position the front wheels straight ahead

and turn the switch to shift into "4H LOCK".

If the vehicle is moving, we recommend

that the speed be less than 100 km/h (60

mph) during this operation.

NOTE:

• When shifting between the transfer

switch position and the transfer gear

position is unmatched, all 4WD indicators

will blink and the buzzer will sound.

• If it is difficult to shift between "4H" and

"4H LOCK" while the vehicle is moving,

try accelerating and decelerating your

vehicle several times after turning the

transfer switch. Be sure to wait until traffic

conditions allow you to accelerate and

decelerate safety before using this procedure.

From 4H LOCK to 4L LOCK

Stop the vehicle completely, place the

transmission in "N" (Neutral) and depress

the brake pedal and the clutch pedal fully

(if equipped), then push in and turn the

switch to shift into "4L LOCK".

From 4L LOCK to 4H LOCK

Stop the vehicle completely, place the

transmission in "N" (Neutral) and depress

the brake pedal and the clutch pedal fully

(if equipped), then push in and turn the

switch to shift into "4H LOCK".

From 4H LOCK to 4H

You can operate the transfer switch either

when the vehicle is stopped or while the

vehicle is moving.

Position the front wheels straight ahead

and turn the switch to shift into "4H". If the

vehicle is moving, we recommend that the

speed be less than 100 km/h (60 mph) during

this operation.

NOTE:

• When shifting between the transfer

switch position and the transfer gear

position is unmatched, all 4WD indicators

will blink and the buzzer will sound.

• If it is difficult to shift between "4H" and

"4H LOCK" while the vehicle is moving,

try accelerating and decelerating your

vehicle several times after turning the

transfer switch. Be sure to wait until traffic

conditions allow you to accelerate and

decelerate safety before using this procedure.

From 4H to N

64J209

Stop the vehicle completely, place the

transmission in "N" (Neutral) and depress

the brake pedal and the clutch pedal fully

(if equipped), then push in and turn the

switch to the mark (1) at the left of the "N"
position, and hold the switch in this posi-

tion for 5 seconds until the "N" indicator

blinks, then turn the switch to the "N" position.

When you turn the transfer switch to the

"N" position, "N" indicator will come on with

the buzzer sound.

CAUTION

• Be sure to stop the vehicle completely

before operating the transfer

switch to shift between "N" and

"4H", or between "4H LOCK" and

"4L LOCK".

• Do not shift between "4H" and "4H

LOCK" unless the front wheels are

in the straight-ahead position and

we recommend that the vehicle

speed be less than 100 km/h (60

mph).

Do not operate the transfer switch

while tires are racing.

• Do not operate your vehicle in "4H

LOCK" or "4L LOCK" on dry, hard

surfaces.

(Continued)

CAUTION

(Continued)

• Do not operate the vehicle while a

4WD mode indicator is blinking

except when shifting between "4H"

and "4L LOCK".

If you operate the vehicle while a

4WD mode indicator is blinking, a

buzzer will sound and the transfer

will shift to "N" (Neutral) to prevent

transfer case damage.

In this case, use the following procedure.

1) Depress the clutch pedal fully (if

equipped) or shift the automatic

transmission gearshift lever to the

"N" position.

2) Turn the transfer switch to the

position previously selected.
3) Operate the transfer switch again.

Check/change transfer case fluid and check the wire connection to it.

i am willing to bet that your silinoid whent out on the transfercase. and can you get it to go into neutral the transfercase that is?

check behind the right side of the front axle and look for 2 vacuum lines to see if they are still connected. also check on driver side just infront of the transfer case and check the vacuum lines to see if they are still connected. usually the problem is the vacuum lines have become caught on something and disconnected themselves.

Hi,
When you switch it from 2H to 4H you can push the switch at any speed but if you switch to 4L the car must be stop and the shifter is in neutral position.
Anyway here is my suggestion.... I would check the switch it self 1st for proper contact, also check the owners manual if there is a fuse for 4X4.
The worse scenario is the 4X4 computer is dead and if you have problem with transfer case you would notice a whining noise.

sounds like the chain is stretched. with vehicle in air you can rotate the front and rear and see how much play is in two yokes. with it in 4hi and will probably hear chain slapping case when you do
