To find the fuse:
1. Consult your owner's manual: This is the best place to start. It will have a diagram of your fuse box(es) and specify the fuse rating and location for the wipers.
2. Locate the fuse box(es): The 2002 Chevy Venture likely has one or two fuse boxes: one under the hood and one inside the vehicle, often under the dashboard.
3. Examine the fuse box diagrams: Each fuse box will have a diagram showing which fuse protects which circuit. Look for a fuse labeled something like "Wipers," "Windshield Wiper Motor," or a similar designation. The amperage rating will also be indicated (usually 15-30 amps).
4. Check the fuse: If you find a blown fuse (it will be visibly broken or burnt), replace it with a fuse of the *same rating*. Using a higher amperage fuse is dangerous and can cause a fire.
If you can't find a blown fuse and your wipers still don't work, the problem is likely elsewhere in the wiper system itself, such as the wiper motor, switch, linkage, or wiring. In that case, you'll need more extensive troubleshooting or professional assistance.
