Went trail riding today now I cant get my 2005 GC out of 4wd lo. Tried low speed shifting, neutral shifting, hard stops, backing nothing worked. Service 4wd System light is on also. Cant hear the transfer case motor engaging. Would welcome any troubleshooting ideas. 98.5 mile tow good thing I've got AAA.
Had same problem with 2 other makes of vehicle & found out the front wheels had to be pointing perfectly straight in front, or we could not get out of 4WD low range.
Hope this may be of assistance to you. Good luck with it.
