Where do you fill the washer fluid for rear wiper on a 2003 Chrysler Town and Country?

The 2003 Chrysler Town & Country uses a single washer fluid reservoir for both the front and rear wipers. There's only one filler cap, usually located under the hood in the engine compartment. You'll find it near the windshield, often with a washer fluid symbol on the cap. There isn't a separate reservoir for the rear wiper.
