1. Identify the Problem:
* Completely Off Track: The window regulator might be broken, the window is completely detached from the regulator, or the regulator itself is dislodged from its mounting points.
* Partially Off Track: The window might be slightly misaligned, caught on a piece of trim, or a regulator component has broken or become loose.
* Binding: The window may be rubbing against the door panel or other components, making it difficult to raise or lower.
2. Access the Window Regulator:
* Door Panel Removal: You'll almost certainly need to remove the interior door panel. This usually involves removing screws (often hidden under trim pieces, armrests, or door handles), carefully prying off clips (be gentle to avoid breaking them!), and disconnecting any electrical connectors (like for the window switch and speakers). Consult a repair manual for your specific model to get detailed instructions. Search online for "1991 Dodge Dynasty door panel removal" – plenty of videos and guides are available.
3. Common Issues and Solutions:
* Broken Regulator: This is the most common cause. You'll need to replace the entire window regulator assembly. These are available online or at auto parts stores. Replacing it involves removing the old one (often requiring removing the window from the regulator) and installing the new one in reverse order.
* Dislodged Regulator: The regulator may have simply come loose from its mounting points. Check for loose screws or broken brackets. Tighten or replace as needed.
* Window Out of its Tracks: Carefully guide the window back into its tracks on the regulator. This often involves manually lifting or lowering the window while gently aligning it with the tracks.
* Bent or Broken Tracks: If the tracks themselves are bent or broken, these may need repair or replacement. This is a more advanced repair and might require more specialized tools.
* Binding: Check for any obstructions preventing smooth movement. Adjust or remove anything interfering with the window's travel.
4. Reassembly:
* Once the window is back on track and the regulator is secure, carefully reassemble the door panel in reverse order of removal. Ensure all clips are properly seated and screws are tightened. Reconnect any electrical connectors.
Important Considerations:
* Repair Manual: A repair manual specific to your 1991 Dodge Dynasty is invaluable. It provides detailed instructions and diagrams. You can often find these online (e.g., Haynes or Chilton manuals).
* Safety: Be cautious when working with sharp objects and electrical connectors. Disconnect the battery's negative terminal before working on the electrical components.
* Patience: This repair can be time-consuming. Take your time, and don't force anything.
* Professional Help: If you're not comfortable working on car repairs, it's best to take it to a qualified mechanic. The cost of professional repair might be less than the cost of damaging your car further.
By systematically following these steps and consulting resources specific to your vehicle, you have a good chance of fixing your off-track window. Remember to always prioritize safety.
