So I’m driving to work this morning, and there is a light rain. I turn my wipers onto the lowest setting (I only have four speeds - off, low, intermediate, and high). Out of nowhere, the wipers sped up by themselves, but only for a couple of swipes, then return to normal. A few minutes later, a repeat. This continues the entire (though short) drive.
So what gives? It’s an older car ('91 Toyota Celica), so it doesn’t have anything fancy like rain-detecting wipers. I tried turning the wipers off and then back on, but that didn’t seem to help.
