There is nothing more frustrating than your subaru power window not working right when you're pulling up to a drive-thru or trying to pay a toll on a rainy day. You press the button, expect that familiar hum, and instead, you get nothing. Or maybe you get a pathetic little groan from the door panel, but the glass doesn't budge.
If you're driving a Forester, Outback, or Impreza, this is actually a pretty common headache. The good news is that a dead window doesn't always mean a massive repair bill at the dealership. Sometimes it's just a quirky computer glitch or a bit of dirt in the wrong place. Let's walk through what's probably going on and how you can get that glass moving again.
Did You accidentally Hit the Lock Switch?
I know, I know. You're probably thinking, "I'm not that silly." But honestly, you'd be surprised how often a subaru power window not working is simply because the window lockout button was bumped.
On most Subarus, there's a small square button on the driver's side armrest, usually right near the main window switches. Its job is to keep kids from playing with the windows in the back, but it often kills power to the passenger side window too. Give it a firm press—on and off—just to be sure. If the window starts working again, you just saved yourself a hundred bucks and a lot of embarrassment.
The "Magic" Subaru Window Reset
If you recently changed your car battery or it went dead overnight, your Subaru might have "forgotten" where the window is supposed to be. This is super common with the "auto-up" and "auto-down" feature. The car's computer loses its calibration and, as a safety measure, it just stops responding correctly.
To fix this, you can try the Subaru window reset dance. It sounds silly, but it works more often than not:
- Turn your ignition to the "On" position (don't necessarily need to start the engine).
- Push the window switch down and hold it until the window is all the way open.
- Once it's open, keep holding that switch down for another 5 to 10 seconds.
- Pull the switch up to close the window and keep holding it up for another 5 to 10 seconds after it's fully closed.
Usually, you'll hear a faint "click" or just notice the auto-feature starts working again. If it was a calibration issue, your window should be back to normal now.
Checking for a Blown Fuse
If you press the button and hear absolutely zero noise—no clicking, no humming, no nothing—you might be looking at a blown fuse. Every electrical component in your Subaru is protected by a fuse, and if there was a power surge or the motor strained too hard, the fuse will pop to prevent a fire.
You'll want to check the fuse box, which is typically located under the dashboard on the driver's side or under the hood. Your owner's manual (or the diagram on the back of the fuse box cover) will tell you which one belongs to the "Power Windows." If the little metal bridge inside the plastic fuse is broken, swap it out for a new one of the same amperage.
Pro tip: If the new fuse blows again immediately, don't keep replacing it. That means you have a short circuit somewhere that needs professional eyes.
Is the Window Motor Actually Dead?
Now we're getting into the slightly more annoying territory. If you hear a grinding noise, or if the window moves incredibly slowly, your motor or the regulator (the mechanical arm that moves the glass) is likely failing.
Subaru window motors are generally pretty tough, but they aren't invincible. Over time, the internal gears can wear down. If you're handy, you can take the door panel off and tap the motor lightly with a screwdriver handle while holding the switch. Sometimes this "shocks" a dying motor back into life for a few more rolls, but it's really just a sign that you need a replacement.
If you hear the motor spinning but the glass isn't moving, the regulator has probably snapped. This is the cable-and-pulley system that actually holds the window. If this breaks, the window might even slide down into the door on its own. Not fun.
Dirt and Grime in the Tracks
Sometimes the issue isn't electrical at all. Think about all the dust, rain, and road salt your car deals with. Over time, the rubber channels (the "tracks") that the window slides in can get sticky or filled with gunk.
If the motor feels like it's struggling, try cleaning those rubber seals. You can use a damp cloth to get the worst of the dirt out, and then apply a little bit of silicone-based lubricant spray into the tracks. Do not use WD-40, as it can actually degrade the rubber over time. Silicone spray keeps things slick and helps the motor slide the glass up and down without breaking a sweat.
The Master Switch Might Be the Culprit
If your driver's side window works fine but you can't control the passenger window from the driver's seat (yet it works fine from the passenger's own switch), the master switch unit is likely the problem.
The driver's side panel is the "brain" for all the windows. Because it's right under the window, it often gets rained on when you open the door. This moisture can corrode the internal contacts. Sometimes you can fix this by spraying some electronic cleaner into the switch, but often, the whole master switch unit needs to be swapped out. It's a fairly easy DIY job—just a few screws and a plastic clip—but the part can be a little pricey.
Broken Wires in the Door Boot
This is one of those "hidden" problems that drives people crazy. Think about how many times you open and close your driver's door. Every time you do, the bundle of wires passing from the car body into the door gets flexed.
Inside that black rubber accordion-looking boot between the door hinges, a wire can eventually snap. If the power wire for your window snaps, you'll have a subaru power window not working no matter how many times you change the fuse or the motor.
To test this, try holding the window switch down while you slowly open and close the door. If the window suddenly jerks or starts moving at a certain angle, you've definitely got a broken wire in that hinge area. Fixing this requires some basic wire stripping and soldering, or a trip to an auto electric shop.
How Much Will It Cost to Fix?
If you're lucky and it's just a reset or a fuse, you're looking at $0 to $10. If you have to go to a mechanic for a motor or regulator replacement, you're probably looking at anywhere from $200 to $500 depending on your Subaru model and local labor rates.
The parts themselves usually cost between $50 and $150 if you buy them online and do the work yourself. It's a bit of a literal "pain in the glass" to get the door panel off without breaking those annoying plastic clips, but it's a great way to save a few hundred bucks on a Saturday afternoon.
Final Thoughts
Dealing with a subaru power window not working is a rite of passage for many car owners. Before you panic and assume you need a brand-new door, go through the basics. Check the lock button, try the reset procedure, and look at the fuses.
Most of the time, your Subaru just needs a little bit of attention or a quick "re-learning" session for its computer. If it turns out to be the motor or a broken wire, at least you'll know exactly what to tell the mechanic so they don't spend three hours "diagnosing" a problem you already figured out.
Keep those tracks clean, don't force the switch if the window is frozen shut in the winter, and your power windows should keep humming along for plenty of miles to come.
