Nothing’s more annoying than a car window that won’t roll up—especially when it starts raining, or you need to park somewhere. This can happen for a variety of reasons, but the good news is that you can usually fix it yourself without needing to call a mechanic. In this guide, I’ll show you how to figure out what’s causing the problem and give you a few easy-to-follow steps on how to fix your car window that won’t roll up.
What Causes a Car Window to Stop Rolling Up?
There are a few common culprits when your car window suddenly stops working:
- Faulty Window Regulator: This is the mechanical part that moves the window up and down.
- Broken Window Switch: Sometimes, the button you press to roll the window up or down can fail.
- Blown Fuse: A blown fuse can cut off power to the window, making it non-functional.
- Electrical Issues: Wiring problems in the car’s electrical system can also prevent the window from working.
Tools You’ll Need to Fix a Car Window That Won’t Roll Up
Before you dive into fixing the problem, make sure you’ve got the right tools on hand. Here’s a list of what you’ll need:
- Screwdriver (flathead and Phillips)
- Multimeter (for checking electrical issues)
- Fuse puller or needle-nose pliers
- Replacement fuse (if needed)
Optional tools that can help:
- Trim removal tool (to access the window switch)
- Suction cup (for temporary fixes)
How to Identify the Cause of the Problem
First, you need to figure out why your window isn’t working. Here’s how to troubleshoot the issue:
- Listen for Motor Sounds: When you press the window switch, do you hear any noise? If the motor is making noise but the window isn’t moving, it’s likely a mechanical issue like the regulator.
- Check the Fuse Box: A blown fuse is an easy fix. Check your car’s manual to locate the fuse for the power windows and see if it’s blown.
- Test the Window Switch: If the fuse is fine, the switch might be the issue. You can test it with a multimeter to see if it’s sending power.
Step-by-Step Guide to Fixing a Car Window That Won’t Roll Up
Step 1: Inspect the Fuse
- Open your car’s fuse box (usually located under the dashboard or in the engine bay).
- Look for the fuse that controls the windows and check if it’s blown.
- If the fuse is blown, replace it with a new one of the same amperage. You can use a fuse puller or needle-nose pliers to remove and install the fuse.
Step 2: Test the Window Switch
- If the fuse is fine, the next step is to test the window switch.
- Pry off the trim panel carefully and disconnect the window switch from the wiring harness.
- Use a multimeter to check if the switch is receiving power and functioning properly. If it’s not, you’ll need to replace the switch.
Step 3: Check the Window Motor and Regulator
- If the fuse and switch are both working, the problem could lie in the window motor or regulator.
- You’ll need to remove the door panel to access the motor and regulator.
- Once exposed, check for any visible damage or disconnects in the regulator or motor.
Step 4: Manually Raise the Window (Temporary Fix)
- If you can’t fix the problem immediately, you can manually raise the window as a temporary solution.
- Use a suction cup or wedge to pull the window up. Secure it with tape or a prop until you can make a permanent repair.
How to Replace a Blown Fuse
Replacing a blown fuse is one of the easiest fixes. Simply:
- Pull out the blown fuse.
- Insert a new fuse with the same amperage.
- Test the window again to see if it works.
If the fuse keeps blowing, there might be an underlying electrical issue that needs to be addressed.
Fix a Faulty Window Switch
If the window switch isn’t working, here’s how to fix it:
- Remove the switch from the door panel by prying it up carefully.
- Disconnect it from the wiring harness and use a multimeter to test for power.
- If the switch is faulty, replace it with a new one. Reconnect the wiring harness and reinstall the switch.
Fix Window Regulator or Motor
If the regulator or motor is faulty, follow these steps:
- Remove the door panel and locate the motor and regulator.
- Check for any broken parts or disconnects in the regulator.
- Replace the damaged part by unscrewing it and installing a new one.
- Reassemble the door panel and test the window.
What to Do if the Window Motor is Burnt Out
If the motor is burnt out, it won’t move the window at all, and you won’t hear any sounds when pressing the switch.
- Purchase a replacement motor.
- Follow the same steps as above to remove the door panel and replace the motor.
- Test the window once the motor is replaced.
Temporary Fixes for Windows That Won’t Roll Up
If you can’t fix the window right away, here are some temporary solutions:
- Use a Suction Cup: Attach a suction cup to the window and pull it up. Secure the window in place with tape or a temporary wedge.
- Manual Pull: Use your hands or a flat tool to gently pull the window up. Again, secure it temporarily until you can make the full repair.
When to Call a Professional
If you’ve tried everything and the window still won’t roll up, or you’re not comfortable with electrical troubleshooting, it’s time to call in a professional. They can diagnose and fix the issue more efficiently if it’s beyond your skill set.

How to Prevent Future Window Problems
Preventative care goes a long way in keeping your car windows functional. Here are some tips to avoid future issues:
- Regular Maintenance: Keep your car’s electrical system in check and have it inspected periodically.
