2013-2019 Legacy & Outback Window Switch Failure: Diagnosis and Replacement

Symptoms of a Failing Door Lock & Window Switch

When the master switch in your 2013-2019 Subaru Legacy or Outback begins to fail, the symptoms can be confusing. You might think a window motor is bad when the real problem lies with the switch on the driver's door. Here are the most common signs of failure:

• Passenger Windows Don't Work From Driver's Door: The most frequent complaint is that the passenger or rear windows can't be operated from the driver's master switch, but they still work using their own individual switches.
• Loss of Auto Up/Down Function: The one-touch automatic up and down feature for the driver's or front passenger's window may stop working. The window might still go up and down if you hold the button, but the auto feature is lost.
• Intermittent Operation: One or more windows or the door locks may work sporadically. This can be caused by worn internal contacts within the switch assembly.
• No Response From Any Button: In cases of complete failure, none of the buttons on the panel will work, including window controls, door locks, and the window lock button. This could also indicate a blown fuse, so it's important to check that first.
• A "Dead" Button: A single button may feel mushy or do nothing when pressed, while all others work correctly. This points to a specific mechanical failure within the switch unit.

Known Issues, TSBs, and Recalls

Subaru has acknowledged issues with the power window switches in these models. Technical Service Bulletin (TSB) 07-155-19, issued in May 2019, addresses customer concerns about inoperative power windows, the inability to operate passenger windows from the master switch, and the failure of the one-touch auto up/down feature. The bulletin announced the availability of new, updated switch assemblies to resolve these problems. For some models, the TSB recommends replacing both the driver's (main) and front passenger's (sub) switches as a set to ensure proper function. There are no active safety recalls for this specific part on these vehicles according to NHTSA data.

Buying a Used Door Lock Switch

A used OEM switch is often a smart and economical choice compared to a new aftermarket part. However, there are critical details to check to ensure you get the right part that will function correctly in your Legacy or Outback.

How to Verify Compatibility

• Check for Dual 'Auto' Windows: This is the most important check. The correct switch for higher-trim models has automatic up/down functionality for BOTH the driver and front passenger windows. Look at the switch itself; you should see the letter 'A' or the word 'AUTO' printed on both front window buttons. Switches with only one 'AUTO' button will not work correctly.
• Match the Part Number (If Possible): The surest way to guarantee a match is to remove your existing switch and compare the part number on the sticker. Subaru has released many updated versions of this part. For example, part number 83071AL58C replaces older versions 83071AL58A and 83071AL58B. Using the latest available part number is always recommended.
• Inspect the Buttons and Housing: Look for a switch with clear, unworn graphics on the buttons. Check for cracks or damage to the plastic housing, especially around the mounting clips. Ensure all buttons press and return crisply without sticking.

Why Used OEM is Often Better

While inexpensive aftermarket switches are available, they often come with compromises. The backlighting may not match the color or brightness of your other interior lights, the button feel can be cheap and less precise, and the internal electronics may not be as durable as the original Subaru part. A quality-inspected, used OEM switch provides the original fit, finish, and reliable performance at a significant discount from a new dealer part.

Replacement Guide

Replacing the master window switch is a straightforward job that most DIYers can complete in under 15 minutes with basic tools.

1. Gather Your Tools: You will need a plastic trim removal tool or a flat-head screwdriver wrapped in tape to prevent scratching.
2. Pry Up the Switch Panel: Start from the front edge (closest to the dashboard) of the switch panel. Insert your trim tool and gently pry upwards. The panel is held in by clips and will pop out.
3. Disconnect the Wiring Harness: Lift the panel up and you will see one or more electrical connectors on the underside. Press the release tab on each connector and pull it straight out to disconnect it.
4. Install the New Switch: Connect the wiring harness to the new switch. You should hear a click as it seats.
5. Test and Reinstall: Before snapping the panel back into place, turn the ignition to the 'ON' position and test all window and lock functions. If everything works, align the clips and press the panel firmly back into the door card.
6. Initialize the Windows: After installation, you must perform the window initialization procedure for both the driver's and passenger's front windows to restore the auto up/down function. With the window fully closed, press and hold the switch down until the window is fully open, then pull and hold the switch up until it is fully closed, continuing to hold for an extra 3-5 seconds.
