The issue with your vehicle’s power window is truly disappointing. Whatever the cause, you’ll certainly be frustrated if the power window doesn’t go up, especially when it’s raining. However, this is a very common problem, but you need to resolve it immediately. So, here are some quick and affordable tips that will help you fix the car window problem without worsening your vehicle’s issue.
The Car Window Doesn’t Roll Up: What Are the Reasons?
The cause of this problem stems from the operating principle of this control system. Some people don’t know that car windows work based on the door’s lift/lower control system. The motor drives the window to rotate, creating an up-and-down motion to open and close the window. Thus, when the motor fails, the gears wear out, and the cables or fuses blow, the window is likely to get stuck or not go up:
- The gear part operates regularly and supports the weight of the glass, so it’s prone to wear. A faulty gear affects the motor’s ability to transmit motion to raise/lower the window.
- If the cable breaks or gets stuck in the twisted shaft, a slight sound will appear when you press the button. At this point, the motor is running but the window doesn’t move.
- Furthermore, the window jamming condition also occurs when the fuse is blown, preventing the motor from controlling the window door.
Ways to Solve the “Car Window Won’t Go Up” Problem
The reasons for your vehicle’s window breaking can be multiple. It’s possible the issue is as simple as a loose connection or as difficult as a faulty switch. Once you’ve identified the problem, you need to fix it with simple and affordable solutions, as mentioned below.
1. Replacing the Blown Fuse
If your car’s power window stops suddenly, the window fuse may have blown. In such a case, you need to change it. You must locate the fuse box and open it. It might be nearby or part of the dashboard. Refer to the owner’s manual for help if you haven’t found it. Now, remove the blown fuse and replace it with a new one having the same amperage. You can refer to some car maintenance tips in case you need assistance.
2. Fixing the Window Seals
Another reason responsible for the “car window won’t go up” problem could be poor-quality window seals. Grease or dirt can accumulate and prevent the seals from closing properly. So, in this case, you need to clean these seals with acetone. Be careful when applying acetone as it can affect your car’s carpet and paint. Once you’ve cleaned these seals, try moving your window now.
3. Changing the Faulty Switch
A possible reason behind this issue could be a faulty switch. To replace this faulty switch, you need to disassemble the window panel. Disconnect the connectors to ensure they provide the proper 12 volts to the switch. You can use a multimeter to check the connector readings. Now, take another switch and plug it into the wiring connectors. And check if it works or not.
4. Replace the Window Regulator or Motor
In such a situation, you need to remove the door panel. You usually need to remove screws to fully take off this panel. Now, check if the motor is receiving the correct reading according to the manual. If the motor is getting the correct value but isn’t working properly, you might need to install a new one. On the other hand, if the motor runs correctly but the window doesn’t respond, you may need to replace the regulator.

Detailed Instructions for Fixing the Car Window Not Going Up:
Step 1: Use a screwdriver to remove the screws holding the window body cover in position.
Step 2: Disconnect and remove the window’s rocker arm.
Step 3: Look carefully at the window regulator and identify the cause of the car window jamming. Check if the cable is stuck or not. If it is, adjust the cable to its original position. If the cable is broken, it must be replaced to continue using it.
Step 4: Check the window seal and replace it if damaged.
Step 5: Check the operating condition of the electric motor, fuse, switch, and wire. If the electric motor works intermittently and inefficiently, the car owner must replace it. If the fuse is damaged or blown, it can also affect the operation of the car window going up/down.
Step 6: Reinstall the car door in its original position.
