I also lost my rain sensing wipers....dealer is following Fords diagnostic steps and now they are waiting for a new wiper motor assembly to arrive. It's been over two months now and no part. I have seen on FRF that Ford is having problems with the wiper motor assembly and also problems sourcing replacements. My thoughts are how could it be the wiper motor when the wipers work fine in all other modes? The have already replaced a computer of some sort that required the steering column removal but I think they need to look elsewhere. Anyone have follow up information on rain sense failure?
