2002 jeep grand cherokee owners manual


the 2002 grand Cherokee WJ jeep,
can be quada-drive ?
or quadra-trac- II NV247 (transfer case)
regardless of that...

stay out of 4wd low,
use low only on ice or dirt, dead slow.
it will grind a bit going into low.
low is never to be used on dry pavement.
dry means, no ice.
the book on car is clear, its for rock crawling off road only. (super low speed)
, put at least on tire on dirt then drive slow and shift out of 4wd LOW, lock,.
if not, damage to the drive line can happen
do not attempt this moving fast ever, (into or out of LOW)

RTM, read it 2 times.

My2002 chevy wont come out of 4 low


Did you fix the E brake problem? Replace the rear cables or cut them at the rear brakes. To much pressure on the T case can keep it from shifting. Especially from 4 low.

I have an 02 chevy trailblazer gear shifter will move but car won't move in reverse or drive now service 4 wheel drive light is on and the switch nuetral is lighting up but its on 2 wheel drive


May be broken 4WD actuator (quite common) which has stuck between engaged and disengaged. Remove and inspect actuator, but first examine all linkage for damage or having come loose.

Service 4wd light on; w4d does not work at all


To start with, a basic engine computer code reader will not connect to the body computer which is why they are not getting any codes.
The 4wd lights will not come on as long as the warning light is on, the system is disabled until it is fixed.
You may need someone with a professional scanner to connect to the body computer.

Instrument panel,blinkers,heater blower, not working after i tried to engage the 4wd. Also the key is stuck in ignition and it wont shift into gear,stuck in park. 2003 trailblazer


First thing to check is the condition of your battery. Don't know what these problems have to do with selecting 4WD. But if battery is weak or dead, you will have all these conditions.

Service four wheel drive light on,cant shift into 4wd cold only ,below 45F,drive awahile resatrt the truck it works fine,warm days no problems .


Vehicles: 2002 Chevrolet Trailblazer 4WD 4.2L SFI DOHC 6-cylinder

Your front 4WD Transfer case is low on Gear Oil.
On warm days, the Gear Oil expands slightly, and is less viscous, so the "Service 4WD" light stays off. On colder days/mornings the story changes.

The following paragraph has info applying to the manual differential only:
The 2002 Trailblazer (the first year Chevy made the Trailblazer) has a Front Differential using 1.11 (that's 1 and 1/9th) Quarts Gear Oil, and a Rear Differential with a capacity of 2.29 (thats 2 and 2/7ths) Quarts Gear Oil.
The Gear Oil needed is GM Part No.12345349 or GM Part No.1052931 (they're identical), also known as "GM Synchromesh"(R), which is a type of GLS (Gear Lubricant, Special), also known as "Manual Synchromesh Transmission Fluid 5W30". A synthetic version of which sells for $12.70/qt (USD) at
http://www.amsoil.com/storefront/mtf.aspx

This is not to be confused with 5W30 motor oil (which can be had for $3.00/qt (USD)).

The 2002 Trailblazer 4WD Transfer Case (NV126 Transfer Case) capacity is 0.8 Liters of GM Part No.12378508 (US), also known as "GM Auto Trak II"(R).
Note that one Quart (US) = 0.946 Liter, so 0.8 Liter = 27.06 ounces.

Red Line sells something that they say replaces both GM Synchromesh and GM Auto-Trak II for $12.14/Qt and $44.55/Gal (US) at

13 Manufacturer Recalls apply to the 2002 Chevrolet Trailblazer (model year 2002 was the first year Chevy offered the Trailblazer), and two recalls pertain to the 4WD Transfer Case. Note that one of the recalls applies to only 895 units, so your vehicle is unlikely to be affected by this Transfer Case recall.

2002 Trailblazer Recall ==========================
OCT 17, 2001 ' Recall ID# 54221

Recall Reason POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE)
Recall Date OCT 17, 2001
Model Affected TRAILBLAZER
Potential Units Affected 78004

Recall Summary
VEHICLE DESCRIPTION: SPORT UTILITY VEHICLES EQUIPPED WITH 4-WHEEL DRIVE. THE CALIBRATION OF THE TRANSFER CASE CONTROL MODULE COULD CAUSE INSUFFICIENT HIGH SPEED GEAR ENGAGEMENT.

Consequence
IF THE GEAR IS NOT ENGAGED, THE VEHICLE CAN ROLL WHEN THE TRANSMISSION IS IN "PARK" AND A CRASH COULD RESULT WITHOUT WARNING.

Remedy
DEALERS WILL UPDATE THE TRANSFER CASE CONTROL MODULE CALIBRATION TO INCREASE GEAR ENGAGEMENT. OWNER NOTIFICATION BEGAN NOVEMBER 6, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020 OR GMC AT 1-800-462-8782.

2002 Trailblazer Recall ============================
SEP 05, 2001 ' Recall ID# 26006

Recall Reason POWER TRAIN:TRANSFER CASE (4-WHEEL DRIVE)
Recall Date SEP 05, 2001
Model Affected TRAILBLAZER
Potential Units Affected 895

Recall Summary
VEHICLE DESCRIPTION: SPORT UTILITY VEHICLES (4 WHEEL-DRIVE). SOME OF THESE VEHICLES WERE BUILT WITH A RANGE SHIFT COLLAR IN THE TRANSMISSION TRANSFER CASE THAT CONTAINS CRACKS.

Consequence
THIS CONDITION COULD RESULT IN A COMPLETE FRACTURE OF THE RANGE SHIFT COLLAR AND SUBSEQUENT LOSS OF VEHICLE FORWARD AND REVERSE GEARS, AND THE INABILITY TO MAINTAIN "PARK" POSITION. THIS INCREASES THE RISK OF A VEHICLE CRASH RESULTING FROM UNINTENDED MOVEMENT OF A PARKED VEHICLE.

Remedy
DEALERS WILL REPLACE THE TRANSFER CASES AND UPDATE THE CONTROL MODULE CALIBRATION. OWNER NOTIFICATION BEGAN SEPTEMBER 6, 2001. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020 OR GMC AT 1-800-462-8782.

How to reset 4wd light for trailblazer 2003


You need to have a high funtion scanner to do this, But there's a problem with the 4wd. system that's causing the light to come on. The same scanner will be able to read the codes.

4x4 sticks when turning corners


if you have selected 4WD then a jerking front end when turning corners is normal. If you are in auto 4WD and it is stuck in 4WD then you need to investigate transfer case switches and mode actuator. You will need a scan tool for this or you will be searching in the dark
