Question Testing Out My 4WD

Okay guys, so im a new '98 TJ owner and total Jee noobie. My dashboard 4wd part time light is not working. According to posts this seems to be a fairly common problem for TJs. I've been attempting to test out my 4WD 4Hi & 4Lo and want to make sure that the problem is the dash light and not the 4wd system.

Some tests I have tried on the 4wd system include the following. I've shifted on the fly into 4hi on a loose rock road and it seems to drive fine, i think. I have also shifted into 4lo while stopped and once again I think it is driving fine, I get alot of power and go slow in 4lo while giving the same amount of gas when compared to 4Hi. I have also shifted into 4Hi while on pavement and doing a sharp turn and can feel my TJ sort of slightly hopping (I know i am not supposed to drive in 4Hi on pavement, as this is a part time system). I haven't notice any grinding sounds or problem while shifting into 4Hi or 4Lo. It has been quite smooth.

Is it safe to assume that I have an electrical problem either a burnt out bulb, messed up switch etc. and that my 4Wd system is fine? Should I try any other tests of the 4Wd to ensure they are working properly? Is there a sure fire way to know my 4wd is fine? Any common trouble signs to listen or look for when shifting into or operating in 4Wd?

Also when i start up my TJ should the 4WD light light up along with all of the other dash lights? Because it is not. Any help would be greatly appreciated! Happy trails to everyone.

Sounds like a burnt out bulb..all dash lights should turn on at key on.

sounds like a bulb is out if the other lights turn on, from my understanding all your lights should light up at start so u know which ones work.
to test i it engages you can park on a smll dirt hill, on the slant part , and in 4wd back up the slant..if your tires dont spin out in back its workin

I have a similar problem. Yesterday I went mudding and sunk it in a puddle (i posted pics in the galley of it in the mud) and ever since then my dashboard light is jacked up. When I put the car in 2 hi for normal driving my dashboar 4 wd light comes on but when I am in 4 wd it doesnt come on..Its completely backwards. Is this something I should be worried about or is this a common problem?

In 4Lo you will never get faster than 20mph-ish. Also in 4Lo from a dead stop you can take off in any gear just fine. 1st, 2nd, 3rd, 4th doesn't matter.

Another way to test 4Hi is to take your rear drive shaft out completely, put it into 4Hi and see if you can still drive forward. You're effectively driving as if you had front wheel drive.

To the OP: The dash light is burned out. On my '99, it used to light up, but then quit. Also, during ignition "dash check" it does not light, indicating the switch is probably ok.

I would suggest not engaging 4W drive when sitting still. 4WLo especially, on my '99, you have to be rolling at 2~3 MPH, set transmission to neutral, then pull back hard into 4WLo. Unless the '98 is different, you have to be rolling forward slowly to avoid potential transfer case damage.

My 97 2.5L auto has to be stopped, trans in neutral and then pull up to get her in 4lo. No sounds, grinds just smoothly goes in.

Most 4wd's require you to be stopped NOT moving when engaging 4LO (in fact, one of our old work trucks wouldn't even TRY to engage 4LO until the vehicle was in Park)...if it'll engage fine while stopped, there is no worry about transfer case damage. Some Jeeps are a little touchy though and sometimes a very light roll is necessary for smooth engagement.

I had the same problem. To ensure that it IS or IS NOT a burnt out bulb, hold the mileage reset button, then turn key one notch up (simultaneously while holding mileage reset button), and it automatically checks ALL indicator lights inside the dash. All my lights turned on, even 4wheel drive indicator light, but not when I engaged 4hi or 4lo. So that ruled out the whole burnt out bulb idea. Instead, I wiggled the wires around under my steering wheel while i had it in 4hi, and VOILA! Always turns on now. Hopefully that's the case for you. Doesn't hurt to try. I NEED the light on....bothers me when it's not on.

I had the same problem. Replace the 4 wheel drive switch on the transfer case. Very easy to do and can be ordered from Quadratec.

Thanks for your help everyone!. I tried holding the mileage reset button a turning the key in the ignition and all of my lights turned on except for the 4WD light. Seems like I have a burnt out bulb. I guess my next step is to open up the dash's control panel. Is it easy to get to the light bulb to replace it? Ayone know where I can find some instructions on how to take it apart?

Pull the defrost trim piece off the top of the dash--the long narrow one that runs across the top; has the defrost vent in the center.

Take the knee bolster trim piece off from below the steering wheel.

If memory serves correctly you will then see two bolts at the bottom and two bolts at the top of the trim piece around the guages. They have a phillips head pattern in them as well. Otherwise they take something like an 8mm socket.

Once that trim piece is off from around the guage cluster, the guages will just pull right out...might be a couple bolts holding it in; I forget. No wires to disconnect. All the contacts are plug in sockets that line up when you put it in.

After that...never taken my guages apart.

Taking it apart MIGHT be a major

At least that's what I've heard....

Another way to try and test 4lo is to engage it and crank the wheel. The jeep should feel like its wanting to hop alil. Probably not the gentlist way to check tho.

piece of cake once you get it unbolted, 4 screws to get it out and pull straight out, not up or down. At that point you can see the back and all the little bulbs. local auto stores should have the replacements

It's easy-peasy. First time I took my cluster out, I think it was all of fifteen minutes to get it all apart, but I did the center console, climate controls, and stereo as well.

...I was bored that day....

autos need to be in N or even P to switch to 4Lo being that when you slide pass N on the Tcase, the output shaft on the tranny will start spinning if the tranny is not in N or P.

My 4WD light went out a year ago, but I know the 4WD still works. I just haven't worried about it, because you'll most certainly know when it's not working

A 4-WD indicator light is relatively new. I've owned 6 or 7 that didn't have one. You'll get by without it

Yeah you can try that. But nobody will recommend that because you can very well break something. Be very careful when you do that . If you try that.

If that lil bit of stress boke your driveline then it was bound to happen anyway.Then do it on a wet surface
