Today I was driving in hard rain on the highway. The windows kept fogging up
even with the defroster, so I turned on my compressor. Whenever I turned on
the compressor, the wipers, set on high, would bog down to low speed. I
turned off the a/c button and the wipers picked up speed again, and so on.

What is this??? It was really weird, something I'd never noticed before.
