I got my truck with no working wipers because there was no switch. I got my hands on a NOS switch and installed tonight...wipers worked off the bat, but was making a lot of noise at the lower part of the windsheild. All the sudden wipers quit right in the middle of the windsheild. Seems like a fuse to me but fuse looks great, and I dont have a new 25 amp fuse to test with. Could my wiper motor have just went out? Any way to test without having a spare fuse on me? Its snowing and I gotta work in the morning, appreciate any insight. Thanks all
