Where do you add washer fluid to rear window dodge caravan 98?

The 1998 Dodge Caravan doesn't have a separate rear washer fluid reservoir. The rear windshield washer fluid is drawn from the same reservoir as the front windshield washer fluid. Therefore, you add washer fluid to the single reservoir, usually located under the hood. Check your owner's manual for the exact location; it's typically a large, translucent plastic container with a cap clearly marked "washer fluid."
