The 1995 and up Jimmy’s and Blazer’s use thesame system for engaging the front diff. They are all made to “shift on the fly” while driving down the road withnothing to do but press the button on the dash. (Do NOT shift into 4 Low while driving at higher speeds at it can dodamage). If the dash light flashes andyou hear a clicking sound that means you have power to the relay. If the vehicle 4 High lights stops flashingand it goes back into 2 High then the problem is likely that you have no vacuumto the 4 X 4 actuator module which is located below the battery tray. Remove the battery and tray; look for a holeburnt in the vacuum line or actuator module rubber diaphragm. When the activator get vacuum it pulls acable that attaches to the front diff engaging it, when engaged the wires onthe front diff send a signal to the 4 X 4 light on the dash telling you it is engaged). If the battery has ever leaked the acid runsdown onto the actuator causing the problem. If no holes found in the hose or actuator diaphragm I would use batterycables and hook up the battery and start vehicle then check for vacuum byputting my finger on the end of the actuator hose. If there is vacuum then problem in actuatoror cable linkage. If no vacuum I wouldthen trace back the vacuum lines to find where it is off or leaking, NOTE: As the heater control operates on vacuum and some other vehicle systemsdo as well bear this in mind, has your vehicle had heater control problems orbeen running rough, this could explain a lot of potential problems. Attached to the hood on the left side(drivers side) on 1997 and older models is a vacuum (a “ball”) canister, newermodels the canister is located in the left fender by the brake module, makesure the vacuum line is attached there. Please rate this suggestion as I never know if it is worth my timefilling these things out…

SOURCE: 4x4 transfer case oil change for 2007 Chevy Tahoe

Go buy the chevrolet shop manual for the truck. Its worth every penny in the long run and will save you thousands by not going to the dealer for everything, because they consult the shop manual. make sure your tranny doesnt share fluid with your transfer case, you could over fill or underfill it easily.

I have a 91 s10 4x4 and the 4 wheel drive wont engauge


There is a vacuume switch with 3 vacuume lines running to it on the top side of the transfer case that is a known problem on push button 4wd. If i remember right the 91 has this and it should take care of your problem. It's called the transfer case switch and it's about $15.

1997 chevy Blazer ZR2 4x4 not engaging


Fab only gave part of an answer. Check the vacuum lines on the driverside firewall. Also check your heater/AC unit make sure the air deflector will change from defrost to vent. If it stays on defrost no matter where you put the knob then you have a disconnected or leaking vacuum line to the dash. If that works and you don't see any open hoses then remove the battery and battery tray. You'll find the actuator there. Remove the vaccum line that goes to it, connect the battery or jumper cables so that you can start the engine. Put it in 4HI and feel for a vacuum at the line. If you do then put it on the actuator and see if it pulls on the cable. If there is no vacuum at that line then the switch at the transfer is bad and isn't sending vacuum to the actuator. If you do have vacuum and the cable didn't pull then change the actuator.

4wheel drive will not engage


There are three main things that could cause this. #1: in the passenger side kick panel is a module that controls the 4x4 and it should be clicking as you try to put it in 4x4.#2:There is a vacume activator switch on the transfer case located on the top on the drivers side.(If the module is clicking and trying to put it in 4x4 then I would just go to this activator switch).#3 If you replace the switch and it still dosn't go in to 4x4 there is a vacum diaphram under the battery tray that pulls the front end into 4x4.Check and make sure that there is vacum getting to the diaphram which is controled by the activator on the transfer case.If no vacume at the activator or diaphram check all the vacume hoses going into and out of the activator.If no vacume while vehicle is running suspect bad vacume line.You will need to remove the battery to test the diaphram under the battery tray.You will need to hook up some kind of battery to the cables with the battery out of the car to get it started in order to check for vacume at the diaphram.

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
