What You'll Learn
Check for a complete circuit in the master switch
If the electric windows of your AU Falcon are malfunctioning, it could be due to a faulty master switch. The master switch for your windows is usually located on the driver's side door panel, and has buttons that control each of your vehicle’s windows independently.
To check for a complete circuit in the master switch, you can perform the following steps:
- Check for proper installation or damage to the window glass mounting and operating hardware. Refer to the appropriate wiring diagrams for your vehicle.
- Inspect the power window switches and window motor. If the master switch still controls the window, the issue is likely electrical rather than mechanical.
- Check for continuity between the rear window driver up and down circuit cavities of the door wire harness connector and the power window motor wire harness connector. Repair any shorted or open circuits as required.
- Reconnect the door wire harness connector and connect the battery negative cable. Check for battery voltage at each cavity in the door wire harness connector, which should be present in the neutral position and one other switch position.
- Consult your owner's manual to determine the location of your power window relay or fuse, and inspect these components. A blown fuse or faulty relay can cause a complete loss of power to the window switches and motor.
If the issue persists, you may need to consult a professional mechanic or a specialised forum for further advice.

Swap the window switches
If you are experiencing issues with the electric windows in your AU Falcon, one of the first things you can try is swapping the window switches. This is because the issue is likely due to worn contacts or the contacts not making a proper connection.
To start, you will need to remove the switch panel from the door. This may involve removing the door trim and checking the connectors. Be careful when removing the trim as it can be soft and easily damaged. You can use a small flat-head screwdriver to pry the connectors loose. Once you have removed the switch panel, you can inspect the switches for any dirt, dust, or food crumbs that may be causing the issue.
If the switches appear to be dirty, you can try cleaning them before attempting to swap them. You can also use silicone spray to help lubricate the window tracks. If cleaning the switches does not resolve the issue, you can then proceed with swapping the switches.
When swapping the switches, ensure that you match the wires correctly. You may need to refer to a diagram or look up the specific power window switch for your car to understand how the connectors fit together and come apart. Once you have swapped the switches, test the windows to see if they are now functioning properly.

Clean the switch contacts
If your Ford Falcon's electric windows are not working, it is likely that the switch contacts are filled with dirt, dust, food crumbs, or other gunk. To fix this, you will need to clean the switch contacts.
First, try swapping the switch for the window that does work. If the window still doesn't work, then it is likely that the switch contacts are dirty and need to be cleaned. Next, remove the door trim and check the connectors for the winder motor. Ensure that they are clean and tight.
If your Falcon is a 2000 model, the passenger side window may not wind up, but the driver controls still work. In this case, you will need to pull apart both the LHF door switch and the main switch and clean the contacts. On the main switch assembly, only clean the contacts for the rocker switch that operates the LHF window. Cleaning the contacts may not guarantee that the switch will work, but it often does the trick. If the contacts are pitted, it may only be a matter of time before the issue occurs again.
It is recommended to use silicone spray to help with the cleaning. This is a cheap and temporary solution that has worked for many Falcon owners.

Replace the reg
If you are experiencing issues with the electric windows of your Ford Falcon, it may be time to replace the reg, or the window regulator. The window regulator is a crucial component of a car's power window system, responsible for raising and lowering the windows. It converts the rotational motion of an electric motor into linear motion, which raises and lowers the window.
Diagnosing the Issue
Before replacing the reg, it is important to diagnose the issue and ensure that the problem lies with the window regulator. Common symptoms of a faulty window regulator include difficulty or inability to raise or lower the window, a window that is not aligned correctly or is crooked, a window that moves slowly or makes noise when in operation, or abnormal noises when the window is moving. A visual inspection of the regulator can help identify any obvious signs of damage or malfunction. Additionally, testing the motor, switch, and connections with a multimeter can aid in diagnosing the problem.
Replacing the Reg
If the window regulator is indeed faulty and beyond repair, it will need to be replaced. This task should be handled by a professional mechanic and will require the removal of the door panel and glass, followed by the installation of a new window regulator.
Maintenance and Repair
To prevent issues with the window regulator, regular inspections and maintenance are crucial. Check for loose connections, worn bushings, or any signs of damage, such as bent or misaligned tracks. If the problem is diagnosed early, a DIY repair may be possible, especially if the issue is with the track or bushings. However, if the problem lies with the motor or gear assembly, professional repair or replacement may be necessary.
Temporary Solutions
In some cases, a temporary solution can be applied until a more permanent fix can be implemented. For example, lubricating the window channels and sliding parts of the window regulator with a special silicone lubricant can help improve its function. However, if lubrication does not solve the issue, the window regulator may still need to be replaced.

Use silicone spray
If your electric windows on your Falcon AU are malfunctioning, one quick fix is to use silicone spray. This is a known issue with the AU models, where the window tracks can become gummy and the motor has to work harder to push the window up. Silicone spray can help with this issue.
Firstly, you will need to take apart the door panel and clean the contacts and switches. Over time, the switch contacts can become clogged with dirt, dust, food crumbs, and other gunk, which can cause the windows to malfunction. Clean these thoroughly before applying any silicone spray.
Once the contacts and switches are clean, you can apply the silicone spray to the window tracks and rubbers. This will help lubricate the tracks, allowing the windows to move up and down more smoothly. It is important to note that some lubricants used by professionals are carcinogenic, so be sure to use a silicone spray that is safe for this purpose.
Silicone spray is a temporary solution, and while it may fix the issue for a short period, it is likely that the problem will persist or reoccur. This is because the window tracks may continue to get clogged or gummed up over time, especially in hot weather. Therefore, it is recommended to also clean the contacts and switches thoroughly and regularly to prevent the issue from happening again.
Overall, silicone spray can be a quick and inexpensive fix for electric window issues in Falcon AU models, but it may not be a long-term solution. Regular cleaning and maintenance of the window components are also important to ensure smooth window operation.
