98 jimmy 4x4 stopped working

Driving my 98 Jimmy, I changed from 2WD to 4WD High no troubles. When I went to change back to 2WD, all of my 4x4 switches flashes then shut off. I am not unable to get back into 4x4. What is the deal?

    I checked the Transfer Case Control Module connections and it looks almost new. After that, now when I I turn the car on the 4WD High switch does not light on like the others on start up. So much snow here and I need to get to work.

SOURCE: 1995 gmc jimmy 4wd high not working

sounds like it is loosing vacuum check all the lines for a crack even the engine lines will cause it to loose vacc. pressure. if it is not run to the vacuum reserve canister you may not have enough vacc. to hold the actuator in several times I just run new lines and that helped and not very costly.

How can I put the suburban into 4x4


I have a 1994 4x4 Suburban. In mine, there's a stick on the hump in the floor, and I'm sure this is the case with yours too. This year model does not require that you get out and lock your wheel hubs. There are labels that are supposed to light up to tell you if you're in 2wd, 4wdHigh, or 2wdLow, but mine don't seem to work. If it's dark out and I can't see the labels, I just have to remember that 4wd High is all the way towards me, 4wd Low is all the way forward, and 2wd in sort of in the middle (but closer to me than the actual middle).

To shift into 4wd High (which is what you'll use for most purposes, like driving in bad weather), just pull that stick back towards you in one swift motion. You can do this while you're parked or while driving forward down the highway.

To shift back out of 4wd High and into 2wd, just push that stick forward a little bit, to where it was before.

To shift into 4wd Low (which is what you'll use only for extreme conditions, like off-road mudding or getting out of your driveway in super deep snow), you have to be stopped. You can NOT just shift into 4wd Low while you're going down the road. First, put it into Neutral (with the shifter on the steering column), Then push that stick on the floor all the way forward. Mine is hard to push, so I use my foot.

To shift back into 2wd from 4wd Low, you need to be stopped and in Neutral also. Pull the stick back towards you to the same position it was in before. (Not all the way towards you, or you'll be in 4wd High instead of 2wd.)

Hope that helps.

The 4x4 is not working on my jimmy. I already replaced the swithc that goes on the dashboarda and still not working. Any ideas??


Check the fuse to the 4x4, if the fuse is good then check the 4x4 electric motor actuator on the transfer case. You should hear it work from 2wd, 4hi to 4low and back to 2wd with the push of the switch. if you don't hear it working then check the wire harness at the actuator motor, look for any damages like corrosion or cracked wire connector clips. If the 4x4 actuator is working on the transfer case, then the front hub 4x4 actuator may have gone bad and that's located on the front differential. It's common for the clip there to corrode and break and is an easy fix with a new collar pin, at worst it's the diaphragm on the vacuum actuator that is located under the battery tray. There is a vacuum switch on the top of the transfer case, driver side but when that fails, your front hub stay's locked in the on position. Good luck and keep me posted and hope it's a simple fuse that has gone bad. You can pick up all these parts at Auto Zone or Parts Source and they will have the step by step instructions for you to get the job done with common tools.

4wd high range does not lite or engage


I had the same problem with my 98 sierra 4x4. Turned out that the electrical activator on the transfer case was not working. It will still go into 4 low but not 4 high. Replace the electrical switch on the transfer case and it should work again.

4 wd low range will sometimes engage 4wd high will never engage


I had a very similar problem with my 98 gmc 2500. The 4 low would engage - though the upshifts were erratic, but no 4 high though the light sometimes came on. I changed out the electric shift solenoid or whatever it is called, on the transfer case and it worked fine after that. A fairly simple fix that can be done in 15 minutes. Hope this helps.
