* Under the hood: This is the most common location. Open the hood and look around the area of the front washer fluid reservoir. You might see a smaller, separate reservoir or a filler cap labeled "Rear Washer" or something similar. It might be tucked away, requiring you to move some components to access it.
* Behind a panel in the engine bay: Some models might have the reservoir tucked behind a plastic panel or cover within the engine compartment. You might need to remove this panel to gain access.
To refill:
1. Locate the reservoir: Carefully inspect the area around the front washer fluid reservoir. Look for a smaller tank, usually plastic, often with a cap that's a different color or size from the front washer fluid cap.
2. Identify the filler cap: Once found, identify the cap of the rear washer fluid reservoir. It might be clearly labeled, or you may need to carefully check the surrounding components for clues.
3. Open the cap: Carefully open the cap, taking care not to spill any fluid.
4. Add washer fluid: Add washer fluid specifically designed for use in cold weather if needed. Don't overfill; leave some space at the top of the reservoir.
5. Close the cap: Securely close the cap.
If you can't find it:
* Consult your owner's manual: This is the best resource. The manual should have a diagram showing the location of all fluid reservoirs.
* Search online: Search for "1999 Ford Explorer rear window washer fluid reservoir location" along with images. This might reveal pictures of the location in a similar model.
* Ask a mechanic or Ford dealership: If all else fails, contact a mechanic or your local Ford dealership for assistance. They can quickly identify the location.
Remember to be careful when working around the engine compartment. Avoid touching hot surfaces, and always disconnect the negative terminal of your battery before performing any electrical work (though this shouldn't be necessary for refilling washer fluid).
