1. Accessing the Window Mechanism:
* Remove the Door Panel: This is crucial. You'll need to carefully remove the interior door panel to expose the window regulator and motor. Consult a repair manual specific to your 1999 Oldsmobile Alero for detailed instructions on panel removal. Generally, this involves removing screws, carefully prying off clips, and disconnecting electrical connectors. Take pictures as you go to help with reassembly.
* Locate the Window: Once the panel is off, you should see the window mechanism. The window itself might be jammed or off-track.
2. Getting the Window Back on Track:
* Manually Realign: This is the trickiest part. You'll likely need to use your hands or long-nose pliers to carefully guide the window back into its proper track within the regulator. The regulator is the system of rollers and gears that moves the window. It's possible the window has simply come off the track and can be easily guided back.
* Identify the Problem: While working, try to identify *why* the window came off track. Is the track itself bent or damaged? Are there any broken pieces in the regulator mechanism? Fixing this underlying cause is crucial to prevent the problem from recurring.
* Use Assistance: You might find it helpful to have a helper hold the window while you manipulate it into the track. One person can guide it, and another can carefully lift and support its weight.
3. Reassembly:
* Reconnect everything: Carefully reinstall all the parts you removed, paying close attention to how they were originally connected. Reconnect electrical connectors securely.
* Test the Window: After reassembly, test the window mechanism. Does it go up and down smoothly? If not, something might still be misaligned.
Important Considerations:
* Repair Manual: A repair manual specific to your 1999 Oldsmobile Alero is highly recommended. It will provide detailed diagrams and instructions for removing the door panel and accessing the window mechanism. Online resources like Haynes or Chilton manuals can be helpful.
* Patience and Care: This is a delicate process. Avoid forcing anything. If you're unsure about any step, seek assistance from a professional mechanic.
* Parts Replacement: If you find broken or damaged parts (such as the track itself or components within the regulator), you will need to replace those. Auto parts stores will have these components available.
If you are not comfortable working on car repairs yourself, it's best to take your Alero to a qualified mechanic. This will avoid potential damage to the door or window mechanism.
