I have a 2011 Ford Fusion SE, and a couple weeks ago the wipers started behaving erratically. They always work, but they’ll pause for a beat or two for no reason, or they’ll work at a slower speed than the one I’ve set them at. They don’t have any issues parking, and they have the range of motion they’re supposed to have. They only do this when it rains. They do not act weirdly if I’m just cleaning my windshield, or if there’s a mist being thrown up from the road but no actual precipitation. A hard rain seems to have more effect than a slight rain (though this could just be skewed observation from using the wipers more during those times).
It seems to me that I should start by seeing if there’s somewhere in the electrical components where water is getting in. I’ve done a little DIY car repair, but not much so I’d appreciate any ideas/advice!
