Tools You'll Need:
* Flathead screwdriver (preferably plastic or nylon to avoid scratching): For prying panels gently.
* Phillips head screwdriver: For removing screws.
* Panel removal tools (optional but highly recommended): These plastic tools help prevent damage to the panel and door.
* New master window switch: Ensure you purchase the correct replacement part for your specific year and model.
Procedure:
1. Disconnect the Battery: This is a crucial safety step to prevent accidental short circuits. Disconnect the negative (-) terminal first.
2. Window Down: Fully lower the driver's side window. This makes the job easier and prevents accidental damage to the window mechanism.
3. Remove the Door Handle: There's usually a small screw hidden beneath the door handle itself (sometimes under a small cover). Remove this screw. Then, carefully pry the door handle away from the door panel. It might be held in with clips; gently work it loose.
4. Remove the Door Panel: Begin by removing the screws along the edge of the door panel. These are usually located around the armrest area and lower edge of the panel. There are typically between 2 and 4 screws.
5. Release the Panel Clips: Once the screws are removed, the door panel is held in place by plastic clips. These clips are usually found along the edges and sometimes near the interior door handle. Starting at the bottom, gently pry the panel away from the door using your flathead screwdriver or panel removal tools. Work your way around the perimeter, carefully releasing each clip. Be extremely gentle as these clips can easily break.
6. Disconnect the Electrical Connectors: Once the panel is loose, carefully disconnect the electrical connectors for the power window switch, door lock switch, and courtesy light. Gently squeeze the connector tabs and pull them apart. Take pictures or make notes of how each connector is attached for easier reassembly.
7. Remove the Window Switch: The master window switch should now be accessible. Unscrew or unclip it from its mounting location.
8. Install the New Switch: Install the new master window switch, ensuring it's properly seated and connected.
9. Reassembly: Carefully reverse the removal steps to reassemble the door panel. Ensure all clips are properly engaged and the screws are tightened.
10. Reconnect the Battery: Reconnect the battery's negative (-) terminal.
11. Test the Window Switch: Test the new master window switch to ensure it's working correctly.
Important Notes:
* Take your time: Rushing the process can easily lead to broken clips or damaged parts.
* Be gentle: Use plastic tools whenever possible to prevent scratching the door panel.
* Take pictures: Taking pictures during disassembly will be invaluable during reassembly.
* Repair Manual: A repair manual specific to your 1992 Subaru Legacy will provide detailed diagrams and instructions. This is highly recommended.
If you're uncomfortable performing this repair yourself, it's best to take your car to a qualified mechanic. Replacing the window switch is generally straightforward, but improper handling can cause damage.
