At first my 4high light was blinking. We replaced the control module. No more lights, no 4wd.
Transfer case motor was beat up n broken, we replaced that. Still nothing.
I've replaced the control module again as directed by a mechanic. And still nothing.

No codes present either.
Fuses all seem fine too.
Theres absolutely nothing going on now, no lights no engaging.

•I've noticed some other things as well,
•When its been stuck I only see one wheel working
•My abs light comes on
•My airbag light has come on and stayed on

If it snows my car can hardly manage to wiggle out. Anyone have suggestions?

 

A good part of the time when a defective part is replaced a computer reset is required and all that involves is to remove the battery negative cable from the battery and connect / hold it on to the positive battery cable end for a few minutes to allow the memory to erase and reset.
Do you have power at the 4WD switch?
Power , I believe comes from the 4WD module.
Let us know what you have so far.
