A power window that rolls down sometimes but refuses to roll back up is more than an annoyance it's a security risk and an invitation for water damage. If you've ever been caught in a parking lot with your window stuck open, you know the frustration. The good news is that this specific symptom works going down intermittently, won't go up at all actually tells you a lot about what's wrong. Narrowing down the cause saves you from replacing parts you don't need and helps you fix the problem faster.

Why does my power window go down but not go back up?

This pattern usually points to one of three things: a failing window switch, a worn-out window motor, or a problem with the wiring between the two. The key detail here is that the window works in one direction but not the other. That rules out a completely dead motor if the motor were totally burned out, the window wouldn't move at all. Instead, it suggests a directional problem in the circuit, which often traces back to the switch contacts.

Inside your power window switch, there are separate contact points for the "up" and "down" commands. Over time, the contacts that handle the "up" direction can corrode, wear down, or lose their connection. The "down" contacts might still work intermittently because they're less worn or have better contact pressure. This is one of the most common causes of this exact symptom.

Is it the switch or the motor causing this?

Before you start buying parts, you need to figure out which component is actually failing. A quick way to narrow it down is to try the window from both the driver's master switch and the individual door switch (if your vehicle has one).

If the window won't go up from either switch, the problem is more likely the motor or the wiring. If it works from one switch but not the other, the bad switch is your culprit. This simple test can save you the cost of an unnecessary part.

For a deeper look at switch-related failures, our guide on fixing a power window switch that goes down but not up walks through the exact steps to test and confirm a bad switch before you replace anything.

Signs the window switch is the problem

• Window works from one switch but not the other
• You hear no click or feel no response when pressing "up" but the motor does respond when pressing "down"
• The switch feels loose, mushy, or inconsistent
• Wiggling or pressing the switch harder sometimes gets the window to move

Signs the window motor is the problem

• Window doesn't respond from any switch
• You hear a faint hum or clicking from inside the door when you press the button
• The window moves slowly or stalls partway up
• The motor works intermittently in both directions before failing completely

Could bad wiring cause a window to go down but not up?

Yes. The wiring harness that runs from the switch to the motor carries separate circuits for each direction. If one wire in the bundle has a break, corrosion, or a loose connector, it can kill the signal in one direction while leaving the other intact. This is especially common in vehicles where the wiring passes through the door hinge area repeated opening and closing of the door flexes the wires until one finally breaks.

Check the rubber boot between the door and the body where the wiring passes through. Pull it back gently and look for wires that are frayed, green with corrosion, or visibly broken. A quick continuity test with a multimeter on each wire in the harness can confirm whether the signal is making it from the switch to the motor. If you need help with that, our article on testing a power window motor with a multimeter covers the process step by step.

What does "rolls down intermittently" actually tell me?

The word "intermittently" is important. If the window goes down every single time you press the button but never goes up, that narrows things down to a directional circuit issue usually the switch or wiring. But if the window sometimes goes down and sometimes doesn't, you're dealing with a component that's failing on a broader level.

An intermittent "down" combined with a dead "up" often means the motor is getting weak but hasn't fully died yet, or there's a loose connection somewhere in the system that affects different directions at different times. The motor might have worn brushes that only make contact in certain positions, causing it to work sporadically.

How do I test the power window motor directly?

The most reliable way to confirm whether the motor itself is healthy is to bypass the switch entirely. You can do this by disconnecting the motor connector at the door and applying 12 volts directly to the motor terminals using jumper wires connected to the battery. If the motor runs smoothly in both directions, the motor and regulator are fine the problem is upstream in the switch or wiring.

If the motor struggles, runs in one direction only, or doesn't respond at all, the motor needs replacement. In many vehicles, the motor and regulator come as one assembly. Our detailed walkthrough on diagnosing a power window motor that won't roll up covers this test in more detail along with what to look for inside the door panel.

Common mistakes when diagnosing this problem

• Replacing the motor without testing it first. Motors are expensive. Always apply direct power to rule out the switch and wiring before buying a new one.
• Ignoring the ground wire. A bad ground connection can cause all sorts of weird symptoms, including one-direction operation. Make sure the motor's ground path is clean and secure.
• Not checking the window track and regulator. If the window is binding in its track, the motor may struggle to push it up (which takes more force due to gravity) but manage to pull it down. Lubricating the tracks or adjusting the regulator can solve the problem without replacing any electrical parts.
• Skipping the fuse check. Some vehicles use separate fuses for up and down circuits, or a shared fuse that feeds different branches. A blown fuse can cut power to one direction only.
• Forgetting about the window lock button. On some cars, the driver's master window lock switch disables all other door switches. If the passenger window won't go up from the passenger switch, try the driver's switch before tearing the door apart.

Quick diagnostic checklist

1. Test the window from both the master switch and the individual door switch
2. Check all related fuses in the fuse box (refer to your owner's manual for the correct fuse)
3. Press the "up" button and listen for any sound from inside the door a click, hum, or grind tells you the switch is sending power
4. Inspect the wiring at the door hinge boot for visible damage or corrosion
5. Apply direct 12V power to the motor connector to test the motor independently
6. If the motor works fine with direct power, test switch continuity with a multimeter
7. Lubricate the window tracks and check for binding before assuming an electrical fault

Next step: Start with the simplest test try the window from the other switch. If it still won't go up, pop the door panel off and test the motor with direct power. That single test tells you whether you're chasing an electrical problem or a motor problem, and it takes about five minutes with a set of jumper wires.
