Check the solenoid on the transfer case - it is vacuum actuated and you may have a problem with the vacuum line.

SOURCE: intermittent 4wd on 98 jimmy

the module is what i would suspect. and i do believe it is in the r kick panel. i've seen the button pack on dash go bad too, but module is best bet.

SOURCE: 4x4 will not engage in 96 gmc yukon

I just fixed a friend of mines 96 yukon...shift to neutral press 4H and u can hear the actuator make noise (we even replaced it with a new one his idea and the same thing happen as old one), so as he hit the switch for 4H i layed under it (on 4 jack stands) and I could hear the motor on the transfer case make a loud noise (well thats working) and before all this I asked him did u check all your fuses (he said guarnteed to be all good) one night it was bothering me so i looked through the owner manual for the yukon and in the fuse box on driver side by the door there are (2) fuse for the 4wheel drive unit,pull one of the fuses good...pulled the other one and it was blown put in a new fuse and it works like brand new..pull fuse for anything that has to do with 4 wheel drive componants,

SOURCE: 4wd will not engage on my 1996 GMC Sierra 1500 pickup

Ok the drive shaft will spin thats good. remove the front driff actuator and see if the plunger extents. if it doesn't check that the power and grond ar ok. If they are then replace the actuator. Just so you know the two actuator may be diffrent. If it has been replaced no problem. If it hasn't ever been replaced then ther is a updated part it come as a kit witha harness spacer and actuator.

Testimonial: "Fixya pointed me in the right direction to find the problem. It was in fact the front actuator which was not expanding. The 4wd is working. Thanks."

4x4 push button is not working about how much does


This is something you can do yourself if you have ever worked on a vehicle before. The part you need is called a front drive actuator valve. It costs about $ 50.00, GM part # 15165891.
Here is some more infor about it:

Main 4wd Components:
TCCM
- Transfer Case Control Module - Located behind the glove box. This is the electronic 'brains' behind the shifting.
Switch - The push button switch in the dash - driver input/indicator.
Encoder Motor - Located on the transfer case - This is what actually shifts the transfer case, and tells the TCCM what position it is in.
Vacuum Switch - Also located on the transfer case - This is what sends vacuum to the vacuum actuator (see below) when the transfer care is in 4HI or 4LO.
Vacuum Actuator - Located under the battery tray - This is what engages or disengages the front driveshaft.
Front Axle Switch - Located on the front axle - This is what tells the TCCM when the front axle is engaged.

If you want to try and replace it yourself, please let me know how it goes.

Front end will not lock in in 4x4 transfer case is in & dash lite shows 4x4 but front wheels don;t lock in


Ok, this is probably going to sound greek if you have no automotive experiance, so here goes:

There are 2 possibilities I can think of at the moment depending on your 4wd system, however there are several things that can cause this

If you have a Push button 4wd (you push a button or turn a knob) the system engages using actuators or sylinoids meening you turn the 4wd on, the switch sends power to the selector option (high and low) and the 4wd light on the dash. the selector determines where the actuator/silenoid engages (either high or low) in the transfer case. However the actuator or silenoid can be faulty and yet the system will say 4wd is on because the switches still sending power to the 4x4 light

The next setup is the manual linkage set up, and given the year of your kia I doubt you have this setup However I am going to go through it anyway.

With a maual linkage setup you engage the trasfer case maualy using the 4wd shifter. Ironically on newer manual shift 4wd systems the dash light is still triggered electrically by location of the shifter not what is going on in the transfer case (Ah a flaw in the design) So if you linkage is loose/bent/damaged or somehow disconnected your 4wd wont engage but the light will still show that it is! Hope this helps

How does my 4x4 push button locker work in my 1989 chevy K1500?


That depends a lot on how your truck is equipped. GM uses several different 4 wheel systems including AWD, Part-Time 4WD, Full-Time 4WD, and ON-Demand AWD. Then there is another version used on some trucks that is a combination of 4WD and On Demand AWD. - it gets a little confusing but each system as slightly different charachteristics.

Genericly speaking, if you have the push-buttons on your dash that say "4-HI", "4-LO", and "2HI" and/or Auto-4WD , the transfer case has an electronicly-controlled stepper motor which shifts the transfer case into the selected mode. An electric solenoid/actuator then engages/disengages the front differential for 2-Wheel or 4-Wheel modes. One push of the button and it shifts the transfer case and engages the front differential.

That's much easier than the old days when you had to stop the truck, get out (Sometimes in the middle of a big mud hole) and lock the front hubs then get back in and play with the lever in the floor to get the transfer case to shift into the desired mode.
