Does a bad 4x4 shift motor have any influence on the rest of the circuit? What I mean is lets say the shift motor is bad, does that effect weather the module clicks or the 4 low/high lites come on? Reason I ask is I can tap on the shift motor and then everything works as it should "for awhile" then next time I start it, nothin works again. No lites or clicking from the module. Trying to determine which component is actually bad.
