1. Diagnosis:
* Identify the problem: Is the window completely unresponsive, does it bind, or does it make unusual noises? This helps determine whether it's a simple cable issue, a motor problem, or something else entirely.
* Check the fuse: Before disassembling anything, check the power window fuse in the fuse box. A blown fuse is the easiest fix.
* Test the motor: With the door panel removed (see step 2), try directly applying 12V power to the motor terminals (carefully!). If the motor doesn't work, it's likely faulty.
2. Accessing the Regulator:
* Remove the door panel: This usually involves removing screws around the door handle, armrest, and speaker (if applicable). There might be plastic clips holding parts of the panel in place; be careful not to break them. Consult a repair manual specific to your year and model Durango for detailed instructions. Numerous videos are available online showing this process.
* Disconnect the window motor connector: Once the panel is off, you'll see the window regulator mechanism. Disconnect the electrical connector to the motor.
3. Repair Options (depending on your diagnosis):
* Cable Replacement: If the cable is broken or frayed, you'll need to replace the entire regulator. This is the most common issue.
* * Removal: Carefully detach the regulator from the window and the door. This often involves unbolting or unclipping the regulator from its mounting points.
* * Installation: Install the new regulator, making sure the cable is properly routed and seated. Pay close attention to how the old one was attached.
* * Re-attach the motor: Secure the motor to the new regulator.
* Motor Replacement: If the motor is faulty (verified in step 1), replace the motor itself. This is usually less common than cable issues, but still possible. You may be able to find replacement motors separately, or you might need a whole new regulator assembly.
* Minor Adjustments: Sometimes, the regulator may be slightly misaligned, causing binding. Careful inspection and minor adjustments might resolve the issue.
4. Reassembly:
* Reconnect the window motor connector.
* Test the window: Carefully operate the window switch to make sure it works correctly.
* Reinstall the door panel: Make sure all screws and clips are securely fastened.
Important Considerations:
* Repair Manual: A repair manual specific to your 2000 Dodge Durango is invaluable. It will provide detailed diagrams and instructions for removing the door panel and accessing the regulator.
* Tools: You'll need various tools such as screwdrivers (Phillips and flathead), possibly a trim removal tool, and possibly a socket set.
* New Parts: Purchase a replacement regulator assembly or motor from a reputable auto parts store. Ensure you get the correct part number for your vehicle.
* Patience: This is not a quick fix. Take your time and be methodical. If you're unsure about any step, it's best to consult a professional.
* Safety: Always disconnect the battery's negative terminal before starting any electrical work.
If you're uncomfortable performing this repair yourself, it's best to take your Durango to a qualified mechanic. The cost of labor could be higher than the cost of the parts, but it saves time and avoids the risk of further damage.
