You can find our wiper switch rebuild kit, which includes all necessary relays plus replacement light bulbs, here: Wiper Switch Rebuild Kit - $20.00 : 13B Etc - Mazda RX-7 Parts And More

We are actually prototyping/testing replacement power window switches right now, and hope to make them available next month. They will be a drop-in, plug-and-play replacement for the factory originals.

I'm VERY interested in that^ I just broke mine.
