the connections near the front axle that activate the motor to engage the system aren't melted? That's a comon problem for that body style. If there good, sounds like it could be that motor itself. To figure out if it's you motor or transfercase, jack up the rear end, have a friend inside shift into 4 wheel drive, or try to, and put it in gear and apply some gas. If the front driveshaft is turning then it's something with the front end. If not, farther back in the system.

SOURCE: 98 chevy s10 blazer turn signal

Unplug the turn signal relay from the fuse box and start you engine. Does it still make that noise?
If yes... Put the relay back in, that is not the problem.
If No...Then the relay could be bad, replace it!

PLEASE RATE THIS SOLUTION! Thank You Very Much!

SOURCE: chevy s10 4 wheel drive will not engage

There is a vaccuum operated switch located on the transfer case that sends vaccum to the accuator that pulls a cable that locks the front end in. Check for vac coming in and out of this switch if no vac out replace it. This switch is a very common problem. You can find them at most parts stores in the help section #49315. please rate.

Find the accuator on the front axle it has a two wire pigtail and threads into the axle housing. Check for power and ground if you have both when the transfer case is in 4x4 the replace the accuator. They are available at most parts stores and are a very common problem. Let me know how it goes.

have one person in the blazer pumping the brake pedal and then hold to the floor, crack the bleeder then tighten, release pedal, repeat till all air is out one side at a time, if this does not work then your ABS unit is bad witch if u follow your lines from your master cylinder u will find a black box with a motor on it, or the master cylinder itself is bad, it also can cause u to have no pedal, replace the master cylinder first, most likely cheaper.

The Selectable Four Wheel Drive (S4WD) Front Axle consist of the following components:
• Differential Carrier Housing
• Differential Case Assembly
• Inner Axle Shaft
• Intermediate Shaft Bearing Assembly (located on the right side of the oil pan)
• Electric Motor Actuator
The front axle on Selectable Four Wheel Drive (S4WD) model vehicles uses a disconnect feature mounted on the right side of the oil pan in order to engage and disengage the front axle. When the driver engages the 4WD system, the Transfer Case Control Module sends a signal to the electric motor actuator to energize and extend the plunger inside. The extended plunger moves the clutch fork and clutch fork sleeve across from the clutch fork outer gear that is splined to the right side wheel drive shaft to the clutch fork inner gear that is splined to the inner axle shaft. The locking of the two gears allows the axle to operate in the same manner as a semi-floating rear axle. A propeller shaft connects the transfer case to the front axle. The differential carrier assembly uses a conventional ring and pinion gear set to transmit the driving force of the engine to the wheels. The open differential allows the wheels to turn at different rates of speed while the axle continues to transmit the driving force. This prevents tire scuffing when going around corners and premature wear on internal axle parts. The ring and pinion set and the differential are contained within the carrier. The axle identification number is located on top of the differential carrier assembly or on a label on the bottom of the right half of differential carrier assembly. The wheel drive shafts are completely flexible assemblies consisting of inner and outer constant velocity CV joints protected by thermoplastic boots and connected by a wheel drive shaft.

A buddy of mine has a s10 2001 blazer and the 4x4 isn't working, and was wondering how to replace the vacuum hose, if this is causing the problem?


2001 does not utilize vacuum to engage the front axel. A cable is used. There are a few conditions that can cause this. The most likely is the encoder motor. It's best to have the vehicle scanned. The TCCM is located behind the right kick panel, sometimes if it's unplugged and plugged back in, it will begin to work again.

Front diff. wont lock into 4x4. Transfer case is working. Vacume Dia. under battery tray is working. Could the shifting fork in the diff be broke


The cable from the differential to the accumulator should move somewhat freely. If it does not, then the cable may be froze up. You can lubricate it with some penetrating oil and work it to free it back up. You may have to remove it to free it up properly.You may find the cable shield towards the bottom end is broke off and the cable may completely be froze up, it's common on the Blazers. You can try pulling on the rod that the cable clips into in the front diff to disengage the front axle. If you cannot get it to engage that way, then you will likely have to pull off the passenger side extension housing to access the engagement collar and fork. If you cannot get it to engage by pulling on the fork in the axle, then you will likely have to disassemble it.

You will likely have to file down the leading edge of the gears. They should be beveled on the sides of the spline to aid in engagement. Hopefully yours is not chipped like the one in the front of my old S10. Mine chipped the splines on the axle and split the collar from being partially engaged under power

The right axle and has splines at the end of it. The Output Shaft slides into the carrier and has large teeth on the other end. The collar it has large teeth inside it that mate with the Output Shaft with the Fork.

The collar rests on the axle, the fork wraps around the collar. Then you push the 4x4 button or shift your transfer case into 4x4 it starts spinning the front drive shaft, which spins the carrier and the short shaft. Now your in 4x4, BUT the front axle needs to lock the right axle with the carrier. A switch on the transfer case routes engine vacuum to a diaphragm under the battery tray, that diaphragm pulls a cable which pulls the collar and forces it over the short shaft. Now your front diff is locked. When you take it out of 4x4 the vacuum switch closes and a spring pushes the fork and collar off the shaft unlocking the front diff.

The problem with mine I think is that the large teeth on the Output Shaft and the inside of the collar are worn at the tips, not allowing them to join together, and the more I drove it around with it clicking, thinking it would lock eventually it just wore the tip of the teeth more.

If that is the problem, You should not have to mess with the differential case. You should be able to get the passenger axle extension tube off, but it may require popping a ball joint, then disconnecting the CV shaft from the axle extension tube, which would allow you to then pull the extension tube.

Good luck and hope it's just the shift cable retaining clip in the housing that broke.

1987 s10 chevy truck 4x4 not engaging


By the way, if that happens again (Same thing happened to me) It was inside the front diff. That vacuum actuator that sits on the passenger side that has a vacuum hose going up to it has a built in cable that plugs into the front diff. There are little springs that go bad and there is no tension on the cable. It retracts but doesn't engage the axle.

It's 3 bolts, then pry it open just enough to get access to the spring that holds the cable together. ;) That's how I fixed my problem permanently

4x4


There are two parts to the 4X4 engagement. One part is the transfer case actually shifting into four wheel, and the second part is the front axle engaging.
If you have a manual shift, as long as the linkage is working, the transfer case is engaged and the problem will be in the front axle. If you have an electronic shift, you can determine if the transfer case is engaged by the lights on the switch. If the switch lighting is correct, the problem is in the front axle. If the lights are not correct, reset the encoder motor module (located behind the ash tray, listen for the clicking when you press the 4X4 button) by disconnecting it for a few seconds and reconnecting it. If this doesn't correct the problem, it's probably the encoder motor. (located on the driver's side of the transfer case) After you change the encoder motor you may have to reset the module again.

Front axle-verify the servo (either air or electric) is operating the clutch fork in the axle by removing the cable end in the axle. Sometimes it's a small shear spring that breaks. Otherwise, usually it's the shim kit and/or fork that need to be replaced. Parts are cheap, but it takes some time because you have a lot of parts to remove.
