I have an 08 ranger 4L. About six months ago I turned the truck on and noticed that my windshield wipers wouldn't turn on and wouldn't spray wiper fluid. I replaced the 30A wiper/washer fuse under the hood and everything went back to working normally. Now six months later the problem is back, but replacing the fuses isn't fixing it this time (I replaced the wiper fuses under the hood and in the cabin). The wipers won't turn on and won't spray water. Does this sound like a faulty wiper motor? Wipers were working fine until they just stopped turning on. I would appreciate any ideas on what the problem may be. Thanks.
