my 4x4 light started flickering on the dash when the 4x4 wouldnt be engaged and then it flipped and flickered when 4x4 was engaged and now the it doesnt come on at all and my 4x4 still works perfectly as far as i can tell no noises or anything like that, just no light on the dash.

any ideas????

 

Sounds like the sensor on the transfer case, my light hasnt worked in over a year, I asked about it on here, and it needs the sensor, I don't think they cost much, just been too lazy to get one.
