This unit (PSA 1137328126, 9222Y8) combines the electric motor and control electronics required to operate the power window smoothly and reliably. It is a direct-fit replacement intended for professional mechanics and experienced DIYers.

Benefits

Direct replacement for OEM part numbers, compact design for easier installation, integrated electronics for stable operation, and durable construction to withstand regular use. Ideal when you need a quick, cost-effective repair without modifying the vehicle’s wiring.

Function And Common Faults

The motor drives the window regulator mechanism to raise and lower the glass via the door switch. Common failure modes include worn carbon brushes, water ingress and corrosion, stripped gears or cable wear inside the regulator. Typical symptoms are slow or intermittent movement, grinding or clicking noises, or a complete loss of window control on the passenger side.

Installation Notes

Typical replacement steps: remove the inner door trim, disconnect the electrical connector, unbolt the motor/regulator assembly and remove the old unit. Fit the new motor, reconnect the wiring and test full up/down travel before reassembling the door panel. As a safety precaution, disconnect the negative battery terminal before working on vehicle electrics. If the regulator mechanism is damaged or binding, replace or repair the regulator assembly together with the motor for long-term reliability.
