Safety First:
* Disconnect the battery's negative terminal before starting any work to prevent accidental shocks or short circuits.
Steps:
1. Access the Door Panel: Carefully remove the interior door panel. This usually involves removing screws around the armrest, door handle, and possibly the speaker grill. There are usually plastic clips holding the panel in place – pry these gently with a plastic trim tool to avoid breaking them. Consult a repair manual for your specific model year's door panel removal procedure.
2. Locate the Window Regulator: Once the panel is removed, you'll see the window regulator mechanism. This is the system of gears, motors, and tracks that move the window.
3. Identify the Problem: Determine exactly how the window has come off the track. Is it just slightly misaligned, or is a component broken? Take photos to help you remember the assembly.
4. Re-align the Window: If the window is simply off track, carefully guide it back onto the regulator's track. This often requires gentle maneuvering and possibly some manipulation of the regulator itself. You might need to use pliers or other tools to help guide the window back in place, but be cautious not to damage the window or regulator components.
5. Inspect for Damage: Check the regulator for broken parts, bent tracks, or worn-out components. Common failure points include the plastic track pieces that guide the window and the gears in the regulator itself.
6. Repair or Replace:
* Minor Repairs: If only minor adjustments are needed, re-assembly might suffice.
* Broken Parts: If plastic clips or tracks are broken, you might be able to find replacement parts online or at an auto parts store. They may come with a repair kit.
* Severe Damage: If the regulator is severely damaged (stripped gears, broken motor), replacement is usually necessary. You can purchase a new regulator assembly from a parts store or online. Be sure to get the correct one for your specific year and model.
7. Reassembly: Carefully reassemble the window regulator, ensuring the window moves smoothly along the tracks. Test the window up and down several times before putting the door panel back on.
8. Reinstall the Door Panel: Carefully replace the door panel, ensuring all clips and screws are securely fastened.
9. Reconnecting the Battery: Once everything is working correctly, reconnect the battery's negative terminal.
10. Test: Test the power window thoroughly to ensure it functions correctly and the window stays on the track.
Important Considerations:
* Repair Manual: A repair manual specific to your 1999 Chrysler Concorde is highly recommended. It will provide detailed instructions and diagrams to guide you through the process.
* Tools: You'll need a set of tools including screwdrivers (Phillips and flathead), plastic trim tools, possibly pliers, and potentially a ratchet and socket set.
* Patience: This is a fiddly repair. Don't rush the process.
If you're uncomfortable performing this repair yourself, consider taking your Concorde to a qualified mechanic. Attempting the repair without proper knowledge could lead to more damage and increased repair costs.
