Have you ever encountered this frustrating issue: your Peugeot 1007's window reaches the top but then automatically lowers halfway? Or perhaps you wish your windows could close automatically when you lock the car, eliminating the risk of forgetting to close them? This article provides a detailed guide on resetting the Peugeot 1007 window system and implementing a DIY modification for auto-closing windows to enhance your driving experience.

When the Peugeot 1007's windows exhibit irregular behavior—such as automatically lowering after reaching the top or requiring intermittent operation to close fully—a window reset is typically necessary. This process allows the window's electronic control unit (ECU) to relearn the upper and lower limits of the window's movement.

1. Lower the Window: Use the window control switch to fully lower the window, then hold the down button for a few seconds to allow the ECU to relearn the "lowered" position.
2. Raise the Window: Next, fully raise the window and hold the up button for a few seconds to enable the ECU to relearn the "raised" position.

After completing these steps, the ECU should have recalibrated the window's limits, resolving the abnormal movement issue.

• Before performing the reset, ensure the window tracks are free of obstructions and apply silicone lubricant to reduce friction.
• If the problem persists after resetting, inspect the window motor or ECU for potential faults.

Understanding the window motor's wiring is essential for diagnosing and resolving window-related issues. Below is a typical wiring diagram for the Peugeot 1007 window motor:

The diagram illustrates the connections between the window motor, control switch, ECU, and power supply. Analyzing this diagram helps clarify the system's operation and aids in troubleshooting.

The Peugeot 1007 does not include an auto-close window feature when locking the vehicle, which can inconvenience some drivers. By installing a comfort window control module, you can enable auto-closing windows upon locking and even remotely lower windows during hot weather for improved comfort.

The core of this modification involves simulating the window control switch's signals to send "auto-up" or "auto-down" commands to the ECU. Analyzing the factory window control switch wiring reveals its operation:

• +12V Power Line: Supplies power to the control switch and illuminates its indicator light.
• Ground Line: Provides grounding for the switch's LED indicator.
• Up Signal Line: Sends an up signal to the ECU when the up button is pressed.
• Down Signal Line: Sends a down signal to the ECU when the down button is pressed.

The ECU detects these signals to determine the window's movement direction and mode. When both up and down signals are detected simultaneously, the ECU interprets this as an "auto mode," triggering full window movement.

Below is a DIY guide for a relay-based comfort window control module that enables auto-closing windows when locking the car.

The module uses the central locking signal as a trigger. Upon receiving the lock signal, it sends a pulse to the "up signal line," followed by a brief delay and a pulse to the "down signal line." The ECU interprets these signals as an "auto-up" command, closing the window automatically.

The module consists of the following components:

• Central Lock Signal Input: Receives the vehicle's lock signal.
• Delay Circuit: Creates a delay between up and down signals to simulate auto mode.
• Relay Control Circuit: Manages the output of up and down signals.
• Switch: Enables manual activation or deactivation of the module.

1. Locate the Central Lock Signal Line: Find the signal line at the door contact switch using a multimeter or test light. Connect the test light's negative to ground and positive to the switch terminals. Lock the car and observe which terminal shows voltage changes—this is the signal line.
2. Connect Power and Ground: Attach the module's power line to the vehicle's +12V supply and the ground line to the chassis.
3. Connect Signal Lines: Link the module's up and down signal lines to the corresponding lines on the window control switch. Verify wire colors carefully, as they may vary by model.
4. Install the Switch: Mount the module's switch in an accessible location, such as the dashboard.
5. Test: Verify the module's functionality after installation.

• Relays (12V): 3 (for up, down, and delay control)
• Diodes: 2 (to prevent signal interference)
• Resistors: As needed (for the delay circuit)
• Capacitors: As needed (for the delay circuit)
• Switch: 1 (to enable/disable the module)
• Wires: As needed
• PCB or breadboard: For circuit assembly
• Enclosure: To protect the circuit

• Disconnect the vehicle's power before modification to prevent short circuits.
• Double-check wire connections to avoid errors.
• Use proper soldering techniques to avoid damaging components.
• Secure the module firmly to prevent loosening.
• Seek professional assistance if unfamiliar with circuitry.

Building on the above solution, you can add a "summer mode" to remotely lower windows for ventilation in hot weather.

This mode operates similarly to auto-close but uses the central locking unlock signal as a trigger. A relay sends an "auto-down" signal to the ECU.

Add a relay to receive the unlock signal and control the down signal. Include a three-position switch to select modes: winter (auto-close only), summer (auto-close and open), and off (no auto functions).

• Relays (12V): 4 (for up, down, delay, and mode switching)
• Diodes: As needed
• Resistors: As needed
• Capacitors: As needed
• Three-position switch: 1 (for mode selection)
• Wires: As needed
• PCB or breadboard
• Enclosure

• Summer mode may increase battery drain—use only when the battery is sufficiently charged.
• Be mindful of surroundings to avoid accidental window operation.

This guide provides comprehensive instructions for resetting Peugeot 1007 windows and implementing an auto-close modification. Whether resolving window malfunctions or enhancing convenience, these solutions offer practical improvements for your vehicle.
