QuestionWhen I turn the switch from 4x2 to 4x4, the light does not come on and it will not lock into 4x4. Someone said it is most probably the control module, does that make sense?
AnswerHi, well it could be the module, the shift motor, the switch, wiring, or a fuse.
Does the $x$ module communicate with a scanner?. Are there any codes?
How are the connections at the shift motor?
Shift motors and control modules are both common failures.
