8 Steps To Fix a Car Window That Won't Roll Up or Down
Sometimes, the window can become stuck either in the up or down position, which can be disappointing, especially when the weather is bad or you want to lock your car. However, knowing the possible causes can help save a lot of time and money. Here are the simple steps for auto glass repair to fix a car window that won’t work.
Step 1: Understanding the Basics
Car windows have electrical motors and a regulator mechanism for raising and lowering the window. By pushing the window switch, you pull a wire, thus making the regulator work and the motor jump into action. Issues with any of these pieces can hinder the operation of the window. Here are the common issues:
- Faulty Window Switch
- Blown Fuse
- Bad Motor
- Regulator Issues
- Wiring Problems
Step 2: Tools and Materials Needed
- Screwdrivers (flathead and Phillips)
- Multimeter
- Pliers
- Replacement parts (switch, motor, regulator, fuses)
- Lubricant spray
- Electrical tape
- Needle-nose pliers
- Trim removal tools
Step 3: Diagnose the Problem
- Check the Other Windows: Attempt to open the other windows to see whether the problem is with the specific window or electrical issues.
- Listen for the Motor: Turn on your ignition, press the window switch, and check whether the motor is making any sound. A faint noise suggests the engine is operating, but the window could be stuck.
- Test the Switch: To test the window switch, use a multimeter and check the reading. Remove the switch from the door panel, set the multimeter to the voltage setting, and press the switch while testing the connectors to fix the stuck car window.
- Inspect the Fuse: Find the fuse; it is often situated under the dashboard or in the car’s engine compartment, particularly to the windows. Check for a blown fuse; if one is found, then replace the fuse with an equivalent capacity fuse.
- Check the Wiring: Before calling a professional to diagnose a problem with the wiring, look for signs of damage. Check for cables that have been stripped or are loose.
Step 4: Remove the Door Panel
- Locate Screws and Fasteners: Use a trim removal tool to pry off the door panel carefully. Most door panels are held in place by screws and plastic fasteners for troubleshooting car windows that won’t work.
- Disconnect Electrical Connectors: Once the door panel is loose, disconnect any electrical connectors for the window switch, speakers, and door lights.
- Remove the Panel: Gently lift the panel away from the door.
Step 5: Inspect the Window Mechanism
- Check the Regulator: Inspect the regulator for any visible damage or misalignment. The regulator is a metal arm set that moves the window up and down.
- Test the Motor: You can access the window motor with the door panel removed. Use the multimeter to test for power at the motor while pressing the window switch. This might help solve the car window issue that won't roll up or down.
Step 6: Replace Faulty Components
Replacing the Window Switch
- Disconnect the old switch and remove it from the door panel.
- Connect the new switch and secure it in place.
- Reconnect the electrical connectors.
Replacing the Motor
- Remove the bolts or screws holding the motor in place.
- Disconnect the motor from the regulator.
- Install the new motor and secure it with bolts or screws.
- Reconnect the electrical connectors.
Replacing the Regulator
- Loosen the bolts or screws holding the regulator in position to replace a rear window regulator.
- Ensure that you detach the old regulator from the door, but very gently, to replace a rear window regulator.
- Replace the old regulator with the new one and fasten it with bolts and screws to fix the car window issue.
- Check that the regulator is properly positioned and fastened to the window to replace a rear window regulator.
Step 7: Test the Window
- Reconnect the Electrical Connectors: After putting the door panel back in place, plug in the electrical connectors for the window switch, speakers, and door lights again.
- Test the Window: Move the window up and down using the switch to test if it glides well, and open it to test the locks. If it does not work, then try tightening all the screws as well as checking all the connections and parts.
Step 8: Reattach the Door Panel
- Reinstall the Door Panel: Before fixing it, place the panel back on the door frame to align with the frame.
- Secure with Screws and Fasteners: Insert back the screws and the fasteners to give the door panel a firmly fixated flooring.
- Final Check: Conduct the final check on the window to confirm that all the components are working properly.
Why won't my power window go up or down?
