I would check the alternator output first. If you have, or can borrow, a multimeter set to 20v d.c., a rough and ready test is to determine the voltage at the Battery terminals with the engine running. 14v or slightly above would be an indication that alternator is charging the Battery. It should maintain that voltage even with a load, e.g. headlights on.

The slow wipers could be a result of low Battery voltage because it isn't charging by the alternator.

Othewise you possibly need a proper diagnosis by a repair garage or auto electrician.
