Question about 2001 Chevrolet Blazer

3 Answers

I just bought a 2001 blazer 4.3 4wd and it was stuck in 4 low

When shifting from 4L to 4H or 2wd should the car be moving or stopped. I got the truck out of 4L but Im afraid to try 4h without doing it properly. Thanks Joel

2WD to 4Wd shifts and 4WD HI to 2WD shifts can be done on the fly while moving. Shifting into 4WD Lo or from 4 WD Lo back requires the transmission placed into neutral, then pushing the appropriate button.

It should tell you on the Shifter whether or not that you can Shift on the Fly. Check the Manual first if there is one in the Truck. Some Models had this and some Did not. Was an Extra from Factory Option.

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.

HOW TO SHIFT TO 4 WHEEL DRIVE


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.

4runner 92 4WD problem


This might sound like a silly question but did you put the truck in neutral before you shifted into 4L ? Reason being transfer case damage can occure if it wasnt in neutral when you shifted into 4L.

Check 4wd light on


just found this worked a trick..mine stuck for two weeks in 2wd

A mere 2,400km into the life of my 07 Rodeo TD 4WD, I used 4L for about 2km of medium-steep/slippery track. After stopping and selecting 2WD the 'Check 4WD' light appeared, meaning I was stuck in 2WD for the rest of that trip. Luckily I was able to complete the trip in 2WD without incident.

The dealer blamed me for 'not following the instructions in the manual' (utter codswallop), 'fixed' it, and very reluctantly gave me a scribbled set of instructions on resetting the system, which I've included below.

When I suggested that these instructions should be included in the manual, the response was 'not necessary if owners use the system correctly'. More cods.

Here's how to reset it:

1. Ignition off, hold all 3 buttons (2H, 4H & 4L) in together

2. Switch ignition on to 'reds' position (last position before start)

3. Hold in this state for 30 seconds

Hope this may be of use !!

I bought a 2000 f150 4x4, 5 speed. the truck


You can try several things. You can stop the vehicle as if you are going into low range and shift the high range 2h, 4h, etc.. Ford advertises the Electric button type as "shift on the fly" but does not say the gears are synchronized to do that with manual engagement.

Change the lube this time to see if the lube is Milky. There have been floods, otherwise the case is sealed whether you park it or drive it. You still could have rust on the shift linkage. You need to move the linkage as you spray it. Then the offbeat chance something was bent from offroading. A Salvage Yard is a wonderful place to learn how a car is built. You may see their part looks different than yours.

Hello i have a 2001 dodge ram 1500 5.9 lt it only has 70 000 miles but i cant get the 4x4 to engage it has the shifter on the floor to put from 2H 4H and 4L but it will not engage


O.K.,tried to get you to tell me more about the problem, but did not see an answer. I find it hard to engage the shifter...have to almost force it... also it takes bit before it actually engages... If I am remembering correctly the truck must be moving as shifted and usually does not engage until turning slightly... this is only from experience (not an expert) and I could count the times I've needed 4x4 to be less than a dozen times since I bought the truck 2 yrs. ago

Neutral is only used when you need to tow the jeep. Normal two wheel driving is done in 2h. To engage 4wheel drive keep rolling slowly and engage either 4h or 4L. Generally 4L is almost never used as it is for pulling weight like a vehicle stuck in a snowbank. If it does not return to 2h when you go back into two wheel operation, many times it will if you back up about ten or twenty feet. Don't engage 4 wheel drive while standing still. and never force the lever if you hear grinding.

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.
