Tools you'll likely need:
* Screwdrivers: Phillips head and possibly flathead, depending on the screws.
* Panel removal tools: These plastic tools help pry off interior panels without scratching them. Be gentle!
* New door handle assembly: Ensure you get the correct part for your specific door (driver's side, passenger's side, etc.).
* Socket wrench (possibly): Some models might require sockets to remove certain fasteners.
General Steps (Exterior Handle):
1. Interior Panel Removal: You'll almost certainly need to remove the interior door panel to access the exterior handle mechanism. This usually involves removing screws around the armrest, door pull, and possibly under the door handle itself. Use panel removal tools to carefully pry the panel away from the door, working your way around the edges. There may be clips that will release with gentle pressure.
2. Disconnect Interior Handle Mechanism: The interior door handle is usually connected to a rod or cable that actuates the locking mechanism. You'll need to disconnect this linkage before removing the panel completely.
3. Access Exterior Handle: Once the interior panel is removed, you should have access to the exterior handle mechanism. There might be screws securing the handle to the door.
4. Remove Exterior Handle: Carefully remove any screws holding the handle in place. Sometimes the handle might simply pull off once the retaining screws are removed, but others might require some gentle prying.
5. Install New Handle: Reverse the removal process to install the new handle. Ensure all screws are tightened securely. Reconnect the interior handle linkage.
6. Reinstall Interior Panel: Carefully reinstall the interior door panel, making sure all clips are properly engaged.
General Steps (Interior Handle):
The process for the interior handle is similar, but you might need to access it through the opening created by removing the exterior handle or directly through the interior panel access.
Important Considerations:
* Take Pictures: Before you start, take pictures of each step. This will be invaluable when reinstalling the parts.
* Patience: This process can be time-consuming and requires patience. Don't rush it.
* Repair Manual: A repair manual specific to your 1999 Toyota Avalon is highly recommended. These manuals provide detailed instructions and diagrams to guide you through the process safely and efficiently. You can often find these online or at auto parts stores.
* Professional Help: If you're uncomfortable working on your car, consider taking it to a qualified mechanic.
This is a general overview. The exact steps will depend on your specific vehicle. Always prioritize safety and consult a repair manual for detailed instructions before attempting this repair. Failing to follow the proper procedures can lead to damage or injury.
