Function And Application
The motor drives the window regulator mechanism to raise and lower the left front window. In affected vehicle variants the unit also supports an electric folding-related function integrated into the door electronics. It is used on Peugeot 407 platforms where the left front door window is electrically operated.
Installation Recommendations
Before starting work, disconnect the vehicle battery to avoid short circuits and unintended activation. Remove the door trim and any vapor barriers carefully to access the regulator and motor. Detach the regulator from the glass and unbolt the motor from the regulator carrier. Swap the electrical connector, install the replacement motor, reassemble the regulator and door trim, then reconnect the battery and test full window travel. Adjust regulator alignment if necessary to avoid binding.
Most Common Failure Reasons
- Wear Of Carbon Brushes And Commutator: Over time the motor brushes wear, leading to reduced performance or intermittent operation.
- Water Ingress And Corrosion: Moisture entering the door can corrode electrical contacts or motor internals.
- Mechanical Wear Of Regulator: Excessive friction or damaged regulator components increase motor load and cause premature failure.
- Obstruction Or Jammed Window: A blocked or misaligned window places extra strain on the motor and can burn it out.
- Connector Or Wiring Faults: Poor contacts or damaged wiring can cause loss of power or erratic function.
Notes For Mechanics And DIYers
This unit is a straightforward replacement for technicians familiar with door trim removal and regulator servicing. Use proper trim tools to avoid damaging clips and seals. After installation verify smooth travel across the full window stroke and listen for abnormal noises that indicate regulator issues. If the door includes additional electrical functions, inspect connectors and door module behavior during testing.
