4 wheel drive solenoids clicking at start up.

[Bowesmobile]

For the past couple weeks the solenoids in the dash are clicking, like they are trying to engage the four wheel drive when I start my Expy. Now only A4WD works as well. Any thoughts on what the problem could be? Its a 1997 Expedition XLT 4.6l.
