My Eagle Won't Move
From Eaglepedia
You put your AMC Eagle in gear one day after having ran it in 4WD and after switching back your car won't move. Or you are switching into 4WD and your car won't move. What has happened is the range selector inside the Transfer Case is in the Neutral position because of a weak/bad shift motor or a leaky vacuum system. The temporary fix is easy, please go to: How To Manually Shift the Transfer Case to view how to do this.
