2010 Ranger Sport V6 Automatic. . . .
Over the last month or so, my wipers (and washers) are intermittently not working. I've pulled and reinserted all the appropriate fuses, and then they worked. Then they didn't. I replaced the multifunction switch 3 days ago and then they worked. And this morning, they don't. Everything else (hazards, brights, turn indicators) related to the multi-function switch worked before, and continue to work with new switch. So it seems there's a problem somewhere else. This is a forever-and-still-in-California truck, so I don't expect a serious corrosion issue. Anyone have any thoughts?
