Does the indicator light come on when you turn the defroster on? Have you checked to see where the wires come in on the rear window to see if they might have gotten disconnected. It usually happens right at the point where the wire connects to the grid.

We have no idea what happened or what plug came out

If you drove a couple of miles without any fluid in any system
you may have problems

If you towed it home or to a shop then you may be okey
