However, here's a general outline of the process for both interior and exterior handles. Remember that this is a *general guideline* and specifics might differ:
For BOTH Interior and Exterior Handles:
1. Disconnect the Battery: This is a crucial safety step to prevent accidental shorts or damage to the electrical system.
2. Remove the Interior Door Panel: This usually involves:
* Removing screws along the edges of the door panel (often hidden under small plastic caps).
* Carefully disconnecting the window crank, power window switch, and door lock mechanism connectors. These are usually clipped in and can be pried loose gently.
* Unclipping the panel itself. These panels are typically held in place by clips. Gently working around the perimeter of the panel will release these clips. Be careful not to break the clips.
3. Access the Handle Mechanism: Once the door panel is removed, you'll see the door handle mechanism. This is where the process differs significantly between the interior and exterior handles.
Exterior Door Handle:
1. Disconnect the exterior handle linkage: There's usually a rod or cable connecting the exterior handle to the interior mechanism. You'll need to disconnect this linkage. The method for disconnecting varies. Your repair manual will show you how.
2. Remove the exterior handle: This often involves removing screws or fasteners holding the handle to the door. Again, this is highly dependent on your specific model's design.
3. Install the new exterior handle: Reverse the removal process to install the new handle, ensuring the linkage is correctly reconnected.
Interior Door Handle:
1. Disconnect the interior handle linkage: The interior handle is usually connected to the locking mechanism and possibly the door release cable. Carefully disconnect these linkages.
2. Remove the interior handle: This usually involves removing screws or fasteners holding the handle to the door panel.
3. Install the new interior handle: Reverse the removal process, making sure all linkages are securely reconnected.
4. Reassemble: Once the new handle is in place, reattach the door panel, reconnect the electrical connectors (window controls, door lock), and replace the screws.
5. Reconnect the battery.
Important Considerations:
* Take Pictures: Before disassembling anything, take numerous photos to help you remember how everything goes back together.
* Patience is Key: Working with car door panels can be frustrating. Take your time and be gentle to avoid breaking clips or damaging parts.
* Parts: Ensure you purchase the correct replacement handle for your specific year and model of Oldsmobile Alero. There are variations between trim levels and even years.
* Professional Help: If you're not comfortable working on your car, it's best to take it to a qualified mechanic. Damaging door panels or the door mechanism can be costly.
Remember, this is a general guide. Always consult a repair manual specific to your 1999 Oldsmobile Alero for detailed instructions and diagrams. The specific steps and techniques can vary significantly.
