Hi d.badde2394,
I may have found a Technical Service Bulletin relating to your concerns:

NUMBER: 03-001-07
GROUP: Differential &
Driveline
DATE: July 21, 2007
SUBJECT:
4WD System May Not Engage Or Disengage As Desired With "SERV 4WD" Message
SYMPTOM/CONDITION:
The vehicle operator may experience one or more of the following conditions:
A). The four wheel drive (4WD) system may not engage or disengage as designed, when
the drive mode is changed between 2WD and either 4WD Auto or 4WD Lock (or back to
2WD from 4WD).
B). An illumination of the “SERV 4WD” message in the Instrument Panel (IP)
C). When four wheel drive (4WD) mode is selected, the amber “4WD” lamp flashes
continuously in the IP signaling that the 4WD system has not been engaged.
D). Diagnostic Trouble Code (DTC) C1464 - Front Axle Disconnect (FAD) High Side
Short To Ground - is present in the TIPM.
This condition may be due to TIPM software and its effect on the FAD actuator
mechanism.

Your certified dealer will be able to best assess if this is a relevant bulletin to your vehicle and if any future steps are necessary. Please let me know if I can be of any further assistance.
