Truck says 4×4 is locked in, but the front tires are not spinning?

My husband is stuck in our yard in our 4×4 F.150. It shows the 4×4 symbol on the dash like it is locked in and we can even hear it locking in, yet the front tires are not spinning. The is not the first time this has happened. Is there something we can do right now to try to get it working? If not after we get someone to pull it out, what things should we checked to find out why it is not working?
It is a 2005. We never had problems with our older model Fords, but I swear they are getting more ragedy each year.
No hubs, it is electric

    If it has manual front hubs you may need to turn the red knob to 'lock'. If they are automatic hubs, get someone to pull you out because they are not working. You'll need to take it to a mechanic to get those looked at.
