Part-Time/Full Time Mix Up

i was driving on the beach earlier, and i always keep it in full time. after a little while i realized that my part time light was on. i looked down and the shifter was in full time position. i did reverse/drive and it didnt change. shifted into part time and the part time light went away! reverse/drive, stayed off. Shifter back to full time and the part time light came on. i left it in full time with the part time light on, and after a moment of driving it went back off.
what couldve caused this?

i tried mine today. Same results, lights showing opposite of what the transfer case is doing. Glad yours worked out though. I crawled under it, some little tube was entirely disconnected. I reconnected it. The wire at the top of the t-case wasnt loose though. Ill lift it up and get under it later on, try and see what the problem is

Are you sure you are in fulltime when the shifter says so? Most likely you need to adjust the shifter linkage and/or replace the fluid in the tc. The switch that turns that light on is controlled by little notches on the shift plate inside the tc. As you shift, the switch hits a notch and turns the light on. Shift into fulltime, it pushes the switch back up and turns the light off. Its a rather simple design. But if it doesnt fully shift, the switch wont make it into the notch to turn the light on. Shift into fulltime and do some tight figure 8s. No binding means you have a problem with the switch itself. If there is binding, you arent in fulltime, you are still in part time.

I replaced my front CV Shafts....put it into part-time/full-time/ then back to two-wheel drive just to test them (with truck on jack stands). Went into 4 wheel ok.

Now Part-Time light is on and doesn't shut off no matter what postion shifter is in.

Fronts don't spin when put in 2-wheel drive (when jacked up) but PT light is still on.

I put it in fulltime and did some tight turns. No binding and the parttime light was still on. So Ill definitely replace fluid in tc. How do i go about adjusting the shifter linkage? This is my 1st jeep and I dont wanna F*** anything up in the process of trying to fix it

Changed the fluid In the tc monday. I listened and could here the click as I shifted through 2wd to 4 fulltimme. When I put it in fulltime, the parttime light came on flickered off and then came back on. I still had to do the drive/reverse thing to get back to 2wd. Should 4wd fulltime turning be as fluent and swift as 2wd?

You should deffinately be able to feel a difference between 2WD and 4FT. Hopefully it is simply a linkage issue and not something more involved such as the shift forks. There are 2 forks -- mode and low range. Ask me how I know...

this should give you some good info, both to adjust the linkage and troubleshoot other issues:

Thanks. Ever since I changed the fluid in the tc everything seems good. I can now hear definite and solid clicks when I move the shifter and I have a friend look below and watch that the arm moves. I put it in 4ft today, did some tight turns-no binding, I can feel the difference and hear it as well...however the parttime light is on. And when I shift to 4pt, it goes off. Ive left it in fulltime all day just makin sure everything checks out. Light does not go away

ignore the light, if you can see the shifter position, and it's right, the light is just there for idiots.

it is a plunger switch and often gets stuck(4pt is a higher notch on the comb than ft). fluid will not fix that, nor will adjusting your linkage. ignore it.
