You need to take the Alternator in for a Bench check. The diodes are probably bad. Wiper switch or motor can be bad. Radio can be smoked.

For wiper motor, the contact points use a system where a derailer mechanically shifts the points to break contact. The contacts are probably fused.

Hi, first thing to do and if you know location of the fuse box take light tester and test each fuse may you find some fuses blew. change theme first. if you change the fuses and the the problem for each item you describe still on that mean damage went to the items you say.

There is no telling what all you burned out from this mistake, how does someone do this???, you could have destroyed every electronic module in the car.

It sounds like you blew fuses other than just the main fuse. Hooking the battery up wrong can destroy major components as well, like the starter, battery, Computer, moduals. You might need a good shop....

the battery was charged backwards,or the battery is hooked up backwards.

chekc your fuses. they should be located under the dash. when you hooked up the battery there could have been a power surge that blew the fuses.

Sounds like you blew a couple of fuses, check the fuse block and replace any blown fuses.  The fuse block is usually under the dash on the drivers side.
Hope this helps, if it does please rate my solution accordingly. Thanks, david

It depends on how long you had the battery hooked up backwards but check for any ground wires/straps from the engine to the frame or body that are burned in to.

a bad fuse ...keep looking .....otherwise the main acc power/ or ground to all those dash areas has been cut or compromised...retrace your steps backwards
