Hello all. New to this forum. I have a 2018 ford focus 2.0 L4 hatchback. My front wipers would not shut off today no matter what position the switch was in. They even kept running when the key was removed. I pulled the fuse F18 and they shut down. Left it out for about 30 mins. Plugged it back in and they would continue going, regardless of switch position. Pulled the battery cover and the negative terminal was corroded. Pulled the battery out, cleaned all the connections, added moisture absorbers, and now they won't turn on at all. Any advice? Also something odd. When I pulled the fuse the second time, both wipers were in the home position. Came back out after 30 mins and the driver side wipers was up, but the passenger was still in home position. Super odd.
