To find it:
1. Locate the fuse panel under the dashboard: This is usually on the driver's side, often near the steering column. You might need to remove a small access panel.
2. Consult your owner's manual: This is the best resource. It will have a diagram showing the fuse and relay locations, specifically identifying the wiper relay. The manual should clearly indicate where the fuse box is and what each component is.
3. Check online forums: Search for "2000 Volkswagen Jetta wiper relay location" on forums like VWVortex. Users have often posted pictures and descriptions of their specific models' locations.
Without your owner's manual, pinpointing the exact location is impossible. Remember to always disconnect the negative battery terminal before working with electrical components.
