The 4x4 works, but nothing to indicate it's engaging on the dash.

Is there a fuse specifically for this? Or some sort of relay?

Thanks

I have always been a little insulted by 4x4 indicator lights. As the operator I like to make it my biz to know little things like what mode the T/C is in or weather the tranny is in reverse or 1st. not a fuse. more likley the switch or bulb.

Crawl under the jeep and disconnect the plug into the transfercase. Jumper the plug with a paperclip and the 4wd light should turn on.

If so then you needs a new switch and remember to buy the o-ring. Shouldn't be more than $20.
Take an old tooth brush and clean around the switch before you remove it. Grit = bad.

But your dealer will prolly be a few bucks cheaper and no shipping.

mine has a wire that is broken i guess or making bad contact. When my 4x4 light doesnt come on I reach under the dash right where my left knee is and wiggle the wires a little this makes the light come on..

Ive had the same problem at times.

I would 'jiggle' the T/C lever, (side to side, up and down) just a little ~ to get the light on. I know its the wiring connection and one day I will clean it up and replace if I need too.

If it was not mentioned, finding an empty parking lot, I would engage the T/C and make a turn, if my wheels are hoping, then I know my 4wd is engaged even if the light is on.

Cheers, hope this is helps !!

Doesn't the clutch override fuse keep that light on. For some reason I think it does.

Thanks for all the input.. I'm heading outside to try to test it, then replace it.. Too bad the switch I got at autozone is a 4 pronger..

Hey there- thank you for the schematic. I found the swtich, and jumped it.. The only light that came on the dash was "Part Time".. Do you think it's the switch? I got in the car and switched between 4H,4N, and 4L but still said "part time".

The only reason I'm trying to get this light to work, is to sell it.. I know the 4x4's working.

part time is the light. that indicates it is in part time 4x4

Yep you wont see any "Full-Time" light on TJ's because they dont have transfer cases equipped with full time 4 wheel drive. But rest assured, part-time is what you want to see, the name simply means that you are only supposed to be using it part of the time. Its only designed to be used in situations where traction isnt good, if you do it on drive pavement for too long, you will screw up your transfer case. It can be confusing, but just know part time is the light you will see when you are in four wheel drive.

My 06 lights up 4wd hi or 4wd lo indicators when 4wd is engaged... Chrysler is anything except consistent.

My light stopped working this summer.
Thanks to this thread, I too - jumped it. And the light works.
Indicating that it's not the bulb, or any connections at the dash.
I will replace the switch and report back, thanks all.

yes need a new switch

This thread should be added to the list of FAQ.
Main reason is, when ya search, several threads come up.
With the info divinitous posted above, and this info here, this will save people some time finding the proper info.

Here is the original switch. It wasn't dirty. It just stopped working. Notice the small black o-ring. Don't reuse it, just get a new one.



Here goes. My light stopped working a few months ago. I pulled the plug, jumped it with a paperclip, and the light works. So I purchased a new switch and o-ring from quadratec like mentioned above. Cheap. This is the part number for the 4x4 switch for the t/c. This bag/part# doesn't come with the 0-ring. See thread above for the part numbers.



Finding the switch isn't easy for n00bs. And the proper tool is seriously needed. An adjustable won't work. A box wrench may work. But I strongly suggest using a rachet. I used a 7/8" deep socket, like a spark plug socket. You will need light, flexibility. And prolly a 1/2 drive to get good leverage. you will prolly not need any wd40 or lub. my jeep has 180,000 miles on it. and this switch came out like a champ.



You want to lay under the jeep. Legs under the rear axle. Head in front of the skid plate, looking back.



Remove harness. Remove switch. Install new o-ring and new switch.



Hope this helps.
I will add that I'm not a mechanic. Anyone can do this with the 7/8" socket. Unless you're a really big guy with huge arms, you may have difficulty reaching in those areas. I'm skinny, and I was a little cramped up. Maybe lifting the jeep up would help in this situation, but I'm not sure. It's a tight area with the frame, driveshaft, and other components. Good luck mates.
