Wiper motors in cars are usually isolated from body with rubber bushing/mounts to prevent transfer of noise to car body. The problem with this is some kind of ground is necessary to make motor work. Usually a wire strap of some kind. This can become non/partially conductive for various reasons and cause intermittent wiper operation.
The rely should be under the passenger side air filter. Remove the filter and unscrew the relay cabin.
