Changing the Windshield Washer Pump:
This is a moderately difficult job, not for complete beginners. You'll need some basic tools and mechanical aptitude. Always disconnect the negative battery terminal before starting any work on your vehicle's electrical system.
1. Gather your tools: You'll need a socket set (likely 10mm or 8mm, check your owner's manual or a parts diagram online for specifics), possibly some pliers or wrenches, and a flathead screwdriver.
2. Access the pump: This is the trickiest part. You'll need to remove parts of the passenger side wheel well liner to get a clear view and access to the pump. This usually involves removing some plastic fasteners, which may break if they're old and brittle (it's a good idea to have replacements on hand). Consult a repair manual or online diagrams to understand how the liner is assembled.
3. Disconnect the electrical connector: Locate the electrical connector plugged into the pump. Carefully unplug it.
4. Disconnect the washer fluid lines: There will be one or two hoses connected to the pump. Use pliers to carefully squeeze the clamps and slide them off the hoses. Have a rag or container ready to catch any spilled washer fluid.
5. Remove the pump: Once the hoses and connector are disconnected, you should be able to remove the pump itself. It might be held in place by a couple of screws or clips.
6. Install the new pump: Follow the steps in reverse order to install the new pump. Make sure the hoses are securely clamped onto the new pump and the electrical connector is properly seated.
7. Reassemble: Put everything back together, carefully securing the wheel well liner.
8. Test: Reconnect the negative battery terminal and test the washer system to make sure the new pump is working correctly.
Important Considerations:
* Repair Manual: A repair manual specific to your 1999 Dodge Caravan is highly recommended. This will provide detailed diagrams and instructions, making the job much easier and less frustrating. You can often find these online or at auto parts stores.
* Parts Diagram: Find a parts diagram online to get a visual of the pump location and surrounding components. This will help you navigate the wheel well and identify the pump.
* Safety: Work in a well-lit area. Wear safety glasses to protect your eyes from debris.
If you're uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. The cost of a professional repair may be less than the frustration and potential damage caused by attempting a DIY repair without the proper knowledge and tools.
