How do you refill the rear washer fluid for a 2000 Ford Expedition?

The 2000 Ford Expedition's rear washer fluid reservoir isn't directly accessible like the front one. There's no separate filler cap. Instead, the rear washer fluid reservoir is filled from the same reservoir as the front windshield washers.

Therefore, to refill the rear washer fluid, you simply add washer fluid to the front windshield washer fluid reservoir. This is usually located under the hood, often near the front of the engine compartment. Look for a large, usually translucent, reservoir with a cap clearly marked "Washer Fluid."

Once you add fluid to the main reservoir, it will fill both the front and rear washer systems.
