1. Access the rear cargo area: Open the rear hatch or liftgate.
2. Locate the access panel: There should be a small access panel, often covered by carpeting or a piece of trim, somewhere in the floor of the cargo area. It might be near the side or even under the spare tire (if you have one). The panel may be held in place by clips or screws. Carefully remove it.
3. Find the reservoir: Once the access panel is removed, you should see a small reservoir for the rear washer fluid. It's typically a plastic bottle or tank.
4. Fill the reservoir: Use a funnel to carefully pour the washer fluid into the reservoir. Don't overfill it. There's usually a visible maximum fill line.
5. Replace the access panel: After filling, carefully replace the access panel, ensuring it's securely fastened.
If you can't find the access panel:
* Check your owner's manual. It should have a diagram showing the location of all fluid reservoirs.
* Search online for "2003 Chrysler Town & Country rear washer fluid location" – images from other owners might help you identify the access point.
Remember to use appropriate washer fluid for the expected temperatures.
