Why is the 4×4 indicator light not working?
This could be a unrelated problem but my driver heated seat also stoped working, the light flashes then turns off but the seat never heats up. Could this be a simple fuse problem or something serious? The 4×4 issue could be the T case shift motor, the transfer case control module, the dash switch, or a fuse controlling any of the above.
What to do if your 4×4 is not working?
If all your 4×4 fuses and wiring are intact with no lights at all your tccm would be the first thing to do. If you notice afterward that it shows a normal 2 hi but malfunctions in 4wd try the steps above. Any noise along the way pinpoint it and have that component inspected.
Is the service 4WD light on or off?
The service 4wd light has been on and stayed on almost the whole time I’ve had this issue. There have been about 3 or 4 times it has went out and stayed out for about a day. Then it would come back on. As of this moment now, the Service 4wd light is on.
Why are there no lights on the selector switch?

Why is my 4 wheel drive light not engaging?
If you don’t shift it into neutral, the 4wd light will continue to flash and won’t get into gear. Seems to be a common occurrence on these trucks. Dodge dealers recommend engaging 4-lo, then back in 2-wheel drive, then back in 4-wheel drive hi (4H). This sequence apparently resolves the problem.
Is the 4WD light working in the snow?
The 4wd light was working just fine. Once I pulled onto my road I needed 4wd again so I pull the lever, hear the quiet clunk, but no light. Playing around with it a little more while putting the plow on in preparation for the increasing snowfall it IS going into 4wd, but no light. Any ideas? Keep in mind it is snowing and I have no garage.
