Ok, I have a 97 discovery that the rear wiper does not work and the r washer either. The #18 fuse is ok. When I press the rear washer button, I can hear the washer motor run but nothing comes out the outslet. This tells me the switch and button work. where do I go now for troubleshooting. Also the rear wiper does not work. Unsure if it is the button or the motor. any troubleshooting steps on that? Front wipers,washers and headlight washers work fine. Thanks
