The 9v battery test doesn't work too well on horns or crossovers. Capacitance is the enemy because it blocks DC and of course your battery is DC. A Woofer will move when the 9v battery is applied, then go back to the original position when the battery is removed. Horns tend to move one way (hence the click you heard), then stay in that position even when you remove the battery. The only way to get it to move back is to re-apply the battery with the polarity reversed. But the fact that you heard something is encouraging.........
I'd test the tweeter by simply running music directly to it at VERY VERY VERY low volume. There's no crossover during this test, so there's nothing to block the damaging lows. So be very very careful to keep SPL down or you'll blow the tweeter. You'll know instantly if the horn is working because you'll hear music. It will sound spitty and trebbly, but it'll sound like music if the horn is OK.
If the horns are OK, then the problem must be in the crossover. Usually when crossovers fail, the leave visual clues. Can you see any components with burn marks or gunk oozing out of them?
