As title states, the first two years I owned it I never had a problem with it. Last winter, the 4WD indicator took a little longer to come on while in 4WD, like about 1/8 mile or so. I just shrugged it off that it was because of the cold. Now it doesn't come on at all, even after having it in 4WD for miles and 20 minutes at a time. Where can I start to hunt down the problem? I've read of a "indicator switch" that sends a signal, but have found no part # or any useful info. Thanks!

EDIT. 4.7 liter if that makes any differance.

 

do you have the lever to engage in 4wd or do you have a switch?

 

its the transfer case position sensor switch got the same problem on my truck its dealer only part thats 100 bucks so i didn't get it i can figure out my self if im in 4wd.

 

Lever on the floor.
