Hi, a very common problem is corroded wires or in the connection to the 4x4 module. The module is located behind the kick panel on the passengers side. If you engage the 4 wheel drive and hear a "rattling noise" coming from that area, that is your problem. If you don't hear anything noise in the cabin, it is probably the actuator...
You should replace the actuator.....

Is there an electric or vacuum switch on a 2001 chevy blazer


There are 2 models here the push button will flash if the system is not engaging or disengaging properly . If front drive shaft is turning. That is with car raised and supported . if front drive axles do not turn then the axle actuator is not engaging axle shaft passenger side. Remove actuator and manually engage shifting collar with a screwdriver still does not turn then inner axle is twisted.

1999 Chevy Suburban stuck in 4wd


Hi Dale, Sometimes the front diff becomes wound up. I am not saying this is the problem with your vehicle but what I'm about to suggest may work as it often does with other four by fours. Make sure you have a clear space to drive the vehicle backwards and forwards at a slow speed. As you do so select the two high position on the selector. You may need to reverse and go forward several times. Hope it works for you. Regards John

2002 Chevy 4wd


maby im wrong but if you rev up and only rear wheels spin that means that it might be 4 wheel drive but not constant 4 wheel drive or diff lock system ,,,, ,, in 4 wheel drive all wheells will turn together but if pressure of slip is bad enough or torque high enough only 2 wheels will drive ,,, thats why diff lock locks wheels together in each axle to over come this ,,, all wheel drive like in landrover locks all 4 wheels together to ensure all wheels rotate to give best grip

4x4 K1500 Chevy Truck, 4 wheel drive repair instructions


There are a number of different hub systems so this may not work but it has worked for me on both auto and manual locking hubs. On a flat surface without traffic. Put the trans into neutral, shift the transfer case into 4x4, shift the trans into reverse and back the truck up 15-20 feet. Completely stop and shift trans into drive. See if this has locked the hubs in. If not, you can also try following the same instructions except shifting into 4wd low. Sometimes the hubs need a "bump" to get them to slip into place. Keep In mind that if the 4 wd low select works, you need to shift it back into 4 wd high before continuing! When taking the truck out of 4wd to 2wd, I recommend the same, shift to neutral, select 2wd, back truck up, shift back to drive and check. Its entirely possible that your hubs need maintenance (they're often overlooked) but hopefully this will get you going. Please let me know if thus worked or if I can offer other suggestions. Good luck!

The four wheel drive on my 1996 Chevrolet C/K 1500 Z71 doesn't seem to be working. I can shift the floor shifter to 4H or 4L and no indicator light comes on and it is only in 2wd. What could be the issue?


Check the 4WD fuse and the illumination fuse in the I/P fuse block. Also check the Transfer Case Switch and the Front Axle Actuator for a fault. I would say that the Front Axle Actuator is the most common failure. I think there is even an updated actuator asy available. Check with you local chevy dealer for price and availability.

You probably have a bad encoder motor.It is located on the side of the transfer case on the drivers side.It is black.The other problem they had with these was the switch but you have already replaced this so your next thing is the encoder motor.Hope this helps.Good luck.

Four wheel drive wont engage. Tranfer case is


Sounds like you either have a vaccum leak or your 4 wheel drive actuator is not working to engage the front differential.On my 98 ram there is a black and red plastic lines that are used for the vaccum lines. They are underneath and go from the transfer case to the front axle, check to see if one or both might be cracked or broke completely.If the lines are good then it could be your actuator on the front axle. A new one is about $93 at advance auto parts and not very hard to replace
