Vacuum hoses and connection under vehicle on transfer case. Sometimes vacuum switch goes bad also. Worst case, the control module for the 4wd

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.

SOURCE: 98 Chevy S10 4wd drive will not engage when button is pushed

your problem sounds like either the transfer case control module located where you hear the clicking sound, or the actuator on the transfer case itself.

try unplugging the transfer case control module and then plug it back in, try engaging 4wd again (make sure your in neutral, coasting at 1-2 mph might help as well) if it still doesn't work check the actuator itself to see if the actuator is trying to engage. if the actuator is trying to engage but doesn't, take the actuator out and check it for wear or damage. if the actuator seems fine and it responds to the buttons when pressed i'd go after the transfer case control module as the culprit. ran into that a few times on those s-10's. 3 out of 4 that i've seen were fixed with a new tccm. 1 of the 4 needed an actuator, check your local junk yard for a working tccm or actuator.

hope this helps!

The vacuum switch on the transfercase is most likely the problem. If you remove it and the plunger is stuck in, replace it and your 4wd should engage again.

SOURCE: replace lower ball joints on a 2000 chevy blazer 4

Raise vehicle up on jack stands so that the stands are under the lower controll arms and the suspension is "loaded" Remove the front tire(s) (if you break the torque on the nuts while the wheel is still on the ground it helps, but do not loosen them completely as you will be looking for new rims and wheel studs too). Place a drift or some other suitable object in one of the brake rotor vanes so that it will hit the brake caliper and stop the rotor from moving and remove the CV shaft nut (it's a big ****** make sure you have the right socket on hand before getting to this point). Next remove the brake caliper and rotor then undo the wheel bearing retaining bolts and remove the wheel bearing. This should give you enough room to move the axle shaft back and up so you can work on the ball joint. If you've had ball joints replaced before just unbolt the ones that are installed and using a pickle fork, or a block of wood and a hammer, drive the ball joint stud from the knuckle. (make sure to support the upper control arm so it doesn't drop down on you when you do this) If you are working on original ball joints then I reccomend placing a block of wood or something else that will protect the cv boots from drill bits ect and drill out the rivets holding the ball joint in place. then remove in the same manner indicated in the previous paragraph. installation is pretty much the reverse of removal and don't forget to torque your cv shaft nut I have a 1999 and the manual specs 103FTlbs... This is a critical torque as it helps preload your wheel bearing. Too high and you'll burn them up, too low and they'll be loose and wear out.

Chevy blazer problems


Hi Cecily,
There are several parts to a blazer 4x4.
First is the transfer case,When you push the button for four wheel, can you hear you it locking up,by pushing the buttons from 4x2 to 4x4 ?
If you here a slight clunking sounds its working. Next Blazers now have to lock in the front wheels. This is done by a vacuum assist. There is a vacuum line from the engine that runs over and under the battery.If it looks like it is attached at the engine, The next part is harder. You need to remove the battery to expose the servo valve that the vacuum is suppose to work.You can start the engine before taking the battery out, it will stay running. Pull the vacuum off the servo to see if its moving.if not replace it. if it is moving, there is a small relay mounted on the fire wall in the center of the fire wall, replace it.

Make sure that the vacuum hose connector is connected AND connected correctly at the transfer case and at the front differential. If that is all right and the front differential still doesn't engage, then you need to test the vacuum actuator at the front differential.

I have a 2000 chevy s10 zr2 4x4 and the four wheel drive isnt working sometimes it will work and others it wont even activate


there is a vacuum actuator under the battery tray. it is the most common cause for this issue. also the cable that goes from that actuator to the differential stretches sometimes causing it to engage and not engage depending on how bad it is.

if you have any more question please ask/

1998 Chevy S10 front axle will not engage when put into 4 wheel


Normal thing that happens as long as onone (worked) on it, is the vacume hose going to the engage sevevo under the battery box has fell of on either end or is brocken on the way there. Then the once or now leaky battery acid ate up this same servo. then the cable going to the front axel breaks sticks falls off or even someone needing one climbed under your truck while parked somewhere to get one to replace their brokeen one now you don't have one then theaxel engage arm or gearset is damaged

Front drive, 4 Wheel drive won't engage


that vacume line goes back to the transfer case, the end that goes behind the motor hooks to a steel tube so it does not get hot from the exhaust., my guess it should be hooked up so it will feed vacume to the vacume ball so it can lock in the axels. if you start the car and shift into 4 wheel drive and listen under hood you should hear a hissing sound, that is vacume, if you can't hear it there, you may have to craw under the right side to hear it, probably came unhooked underneith the car
