Digitaltwist, your first step should be to remove the tweeter from the cabinet, and make sure it is still connected. Your solution may involve nothing more than a quick reconnect with the soldering iron, etc.
If the tweeter is connected, ensure that the wiring from the tweeter back is OK. Make sure that all appears fine through the crossover.
Next is to connect the tweeter to a speaker cable, via wires/alligator clips. This is the last thing to try, and will absolutely tell you if the tweeter is gone. Of course, make sure to be very judicious with the volume, as you wouldn't want to blow the tweeter now.
If nothing comes of this, you will need to purchase a replacement.
Good luck!
