Before, vehicles used to wind their windows with a crank. Modern vehicles were designed with a power window motor to make it more convenient. The motor turns the electronic signal from the electronic switch; and turns it into mechanical energy which activates a window regulator. When activated, the regulator moves the windows up or down. But due to years of constant use, the power window motor will fail and it needs to be replaced.
In this guide, we have prepared the tips, tools, and step that you will need to replace your vehicle's power window motor.
Difficulty Level: Moderate
Tools that You'll Need:
- A set of screwdrivers and sockets
- Fuse-pulling tools
- Trimming tool
- Packaging tape
- Replacement power window motor
- Always wear recommended safety equipment like closed-toe shoes, an industrial-grade dusk mask, safety goggles and gloves.
- Make sure to disconnect the battery before working on this project. Exercise caution when working on your vehicle's electrical parts.
Step 1: Locate your vehicle's fuse box and check if the window motor's fuse is blown
Step 2: Test the windows by pressing on the door panel window switch. Check if they are rolling all the way up or down.
Step 3: Check the adapter plugs on the window switch for damage. If you see signs of excessive moisture or burnt marks, replace them too.
Step 4: Use a screwdriver to remove the screws securing the door panel. Carefully remove the door panel from its plastic rivets to gain access to the window motor.
Step 5:Remove any trim pins with your trimming tool. Lift the door panel by hand and set it aside.
Step 6:Carefully shove the glass window into the door frame by hand. Tape it to the door frame with packaging tape. Apply the right amount of pressure when working on glass so it won't break.
Step 7:With your socket wrench, remove the bolts connecting the motor to the regulator and door.
Step 8:If you see any worn out joints on the window regulator, make sure to replace them too.
Step 9:Unplug all the wires connected to the old motor. Use the socket wrench to remove the motor from its mount bolts.
Step 10:Once you've pulled the motor out, install the replacement motor into the regulator mechanism. Secure it with the mount bolts and reconnect all the wiring harness to it. Press firmly on the adapter plugs to reconnect them
Step 11:Reinstall the door panel and use your hands to pop the rivets back into place. Secure it with screws and bolts. Make sure that all window switches have been seated properly.
Step 12:Remove all the packaging tape used to secure the glass windows before testing the power window motor.
Step 13:Reconnect the battery terminals and check if the new motors are working properly.
Installing a new power window motor will take about an hour and a half for an expert DIYer and two hours for a beginner. Get your hands dirty and have fun with this project.
