SOURCE: s10 4x4 wont work

check the fuses supplying the front viscous-coupling system solenoids, there should be at least one fuse for this marked AWD or 4WD. Also the locking hubs or the front differential may be damaged from engaging 4x4 while moving.

If it is an auto then the fuse or box fluid levels are likely areas to check.

If the fuse is found to be intact, check the relays click when 4x4 is selected, and replace the necessary relay if it does not operate.

You will need the service manual for your car to locate and identify the correct electrical equipment for the 4x4 function.

SOURCE: 1996 Yukon 4X4 Electronic Shift on Fly.

I had the same problem with the shift on the fly push-button 4x4 on my 97 Suburban. GM Shop manual indicates that it could be due to an encoder error on the actuator motor. Try pulling the transfer case fuse to reset the transfer case control module. Wait at least one minute. Re-install fuse then re-try operation. Did it last week and that saved me a trip to the dealership and extensive troubleshooting.

Will not shift into 4x4 drive

The Front Axle Actuator is probably your problem. I have replaced my Actuator TWICE in the last 7 years.... The Reason for the Service 4WD was the Failed Attempt. If you are able to test the Power going to the Actuator and there is none, then you have one of 3 switches that went bad but Chevrolet/GM is known for having the Defective Actuators. Aftermarket Actuators are available.

95 chevy blazer 4x4 not working

The front differential actuator is the most common issue and sits under the battery tray. The diaphragm will leak or the cable will corrode not allowing the front differential to lock in.

4x4 lights flash dont engage

I have a 2001 chevy blazer and for the last three years when i tried to engage by 4x4 the light would just flash, in any mode, low, high, or auto. I found a vacuum hose disconected located near the top center of the firewall. I plugged it in and i was good to go. After researching I found it is a common problem. The hose goes to the actuator under the battery.

97 gmc sierra won't go into 4x4. Electronic

Take the front axle actuator out of the axle. Plug it back in and have some one push the 4x4 button. The actuator should move, it's a liniar motor. If it doesn't then the actuator is bad or there is a wiring problem. If it does there is a problem in your front diff or some where else in the system.
I'd take a guess and say it's the front actuator.

4x4 indicator light flashes continuesly

Hi, on the front axle is the actuator for the free wheel hub. This actuator works with vacuum. You will need to establish if you have sufficient vacuum on the actuator. You should have vacuum on one side of the actuator in 4x2 mode and then the vacuum should change to the other side when 4x4 mode is selected. If your vacuum is fine and the actuator moves far enough, then you should look at the freewheel sensor situated on the front diff. The sensor might be faulty which gives the control unit the wrong info.

Electronic 4x4 will not disengage

Sounds like the shift motor on the transfer case is bad. You replaced the actuator on the front differential right?
