How to Fix a Honda Window Regulator
With a power window regulator, you no longer have to use a hand crank just to roll the windows of your Honda up and down. All it takes is just a push of a button for your power window to slide up if you want to get a taste of the fresh air outside or to go down if you want to keep the cabin comfy with cooled or heated air or don't want strong winds, rain, or snow to get inside. If that push of a button didn't work, chances are, your Honda window power regulator is busted. We can help you figure it out. Here are the steps for troubleshooting the problem as well as replacing the component easily:
Difficulty level: Moderate
Things you'll need:
- New power window regulator
- Open-end wrench
- Screwdriver (small slotted)
- Socket wrench set
- Nut driver
- Masking tape
- Digital voltage meter
Note: You can also use an upholstery removal tool to easily access the door panel for window regulator replacement.
Step 1: Inspect the old motor and window regulator to be sure that these are causing the power window problem or malfunction. Get access to the regulator by removing the front channel and the mounting bolts. With a digital voltage meter, test the regulator before you disengage it. If the reading is less than 12, the problem is on the wiring and switches, which means you have to check the fuses and switches. If the reading is 12, this means that the wiring and switches are receiving power from the motor. You have to remove the old regulator and replace it.
Step 2:Pry off the plastic access panels on the interior door panel using a small slotted screwdriver. After this, you can now remove the electric window switch plate from the door panel with the screwdriver. To get the window switch plate out of the way, you have to unplug the electrical connector. This is at the back of the electric window switch. Use a nut driver to undo the bolts that hold the interior door panel to the frame. Find all the screws that connect the panel to the frame and remove them with a screwdriver. You also have to disconnect the wiring connectors at the back of the door panel so that you can set the panel off the frame.
Note: To prevent electric shock as you inspect and replace the old power window regulator, you have to disconnect the vehicle's negative battery cable using an open-end wrench.
Step 3: Look for the power window regulator as you pull the plastic liner back. You have to slide the glass window carefully using your hand. To keep the glass in place as you replace the window regulator, put some masking tape around the top of the window frame and on both sides. Next, you have to disengage the electrical connector on the motor. Use a socket wrench to unfasten the bolts that hold the regulator and motor to the door frame. After this, you can disconnect the motor from the regulator and remove the regulator.
Note: As you remove the regulator, you have to be careful with the gear spring as this can snap. For your safety, wear protective gloves.
Step 4:Install the new Honda window regulator. Connect it to the motor and attach the assembly to the door frame using the bolts to keep it in place. Re-attach the liner back over the frame and then connect the wiring connectors to the back of the door panel. Set the panel onto the door frame and fasten it with bolts and screws. You have to re-attach the electrical connector to the back of the window switch. After this, you have to snap the switch back in place. Finally, put back the access panels to the door panel and fasten it by hand.
Note: Once you're done putting things back in place, connect the negative battery cable to the battery post.
Step 5:Test the power windows to see if they're running smoothly now that you have replaced the old Honda window regulator.
