* Repair Manuals: A factory service manual (FSM) or a Haynes/Chilton repair manual will have the most comprehensive wiring diagrams. These are usually available online from retailers like Amazon or eBay, or from automotive parts stores. Factory manuals are generally more detailed.
* Online Forums: Websites and forums dedicated to Dodge Durangos (like DodgeForum.com or similar) often have members who have shared wiring diagrams or can point you in the right direction. Search the forum using keywords like "1999 Durango wiring diagram" or a more specific search related to the system you're working on (e.g., "1999 Durango headlight wiring"). Be cautious about the accuracy of information found on forums.
* Automotive Parts Stores (Sometimes): Some larger auto parts stores might have access to wiring diagrams through their computer systems, but this isn't guaranteed. It often depends on the specific store and their resources.
* AllDataDIY or Mitchell 1: These are subscription-based online resources that provide comprehensive repair information, including wiring diagrams, for many vehicle makes and models. They are typically used by professional mechanics, but individuals can also subscribe.
Important Considerations:
* Specificity: The more specific you can be with your search, the better. Instead of just "wiring diagram," try specifying the system you need (e.g., "1999 Dodge Durango power window wiring diagram," or "1999 Dodge Durango ABS wiring diagram").
* Accuracy: Always double-check any wiring diagram you find against your vehicle. Wiring can vary slightly based on options and trim level.
* Safety: Working with car electrical systems can be dangerous. If you are not comfortable working with electricity, consult a qualified mechanic.
Remember to always disconnect the negative battery terminal before working on any electrical system in your vehicle to prevent shorts and potential damage.
