before messing with the windshield, look on the driver side, under the dash, and make sure everything is connected. You may have just disconnected the wiring. when I took my windshield down to replace mine, i opened up a brand new can of worms (broke my windshield hinges, and found stuff I would not have noticed that needed replaced.) After replacing the hinges, the doors don't fit on quite right, and it is just a PITA if you don't have to. Look at the connections first. If you are unsure which it is, the wiring is the only wiring that goes all the way up to where the tub meets the windshield, so you can follow it with your hand.
Good luck, and I hope it is just the connection.
