The 711W62645-6051 Left Door Power Window Motor is a critical electrical drive component in the cab of SINOTRUK Howo trucks. It converts 24V DC electrical power into controlled rotary motion, driving the window regulator mechanism to raise and lower the driver’s side window smoothly and reliably.
This 711W62645-6051 motor is precision-manufactured to exact OEM dimensions. The stator and rotor laminations are stacked and bonded for low loss, the commutator is machined for smooth brush contact, and the output shaft runs on pre-lubricated sealed bearings. The mounting holes match the factory regulator bracket exactly.
Common signs that a window motor needs replacement include slow or stalled window movement, unusual noise or grinding, a window that fails to raise or lower, excessive current draw, blown fuses, and visible wear on the drive gear. Fitting a new 711W62645-6051 motor restores smooth window operation and driver comfort.
Whether you are repairing a faulty window lift system, replacing a worn motor or carrying out preventive maintenance on a fleet of Howo trucks, the 711W62645-6051 Left Door Power Window Motor delivers the quality, reliability and durability that SINOTRUK Howo professionals expect.
The 711W62645-6051 Left Door Power Window Motor is designed for SINOTRUK Howo trucks, with primary compatibility across the A7, T7H, HOWO 371 and HOWO 380 series. It is a direct OE replacement, so it bolts to the original window regulator and connects to the factory door harness without modification.
This motor is essential in applications where driver comfort and reliable window operation are critical, such as long-haul transport, construction, mining and municipal service. In these duties, the motor must deliver consistent torque without overheating and resist vibration, dust, heat and moisture.
When replacing the window motor, it is recommended to inspect the window regulator mechanism, glass run channels, switch, fuse and relay for wear or damage. The 711W62645-6051 is designed to work with the factory window lift system, ensuring correct torque and reliable operation.
For fleets with multiple HOWO trucks, standardising on the 711W62645-6051 Left Door Power Window Motor simplifies electrical repair inventory and ensures the correct motor is available for scheduled maintenance or emergency repairs.
Replacing the 711W62645-6051 Left Door Power Window Motor is a moderately simple procedure that requires basic electrical and mechanical knowledge. This work should be performed by a qualified technician. Begin by disconnecting the battery negative terminal to prevent accidental short circuits.
Remove the left door trim panel to access the window motor. Disconnect the electrical connector and remove the mounting bolts holding the motor to the regulator. Withdraw the old motor, taking care not to damage the regulator mechanism or glass. Inspect the drive gear and regulator for wear.
Fit the new 711W62645-6051 motor onto the regulator and secure it with the original hardware. Reconnect the electrical connector until it clicks into place. Reconnect the battery and test the window through its full range of motion. Confirm smooth operation without binding or excessive noise.
For ongoing maintenance, periodically check that the motor is securely mounted and that the connector is free from moisture or dirt. If window operation becomes slow or noisy, inspect the regulator and run channels before replacing the motor again.
The 711W62645-6051 Left Door Power Window Motor is manufactured in an ISO 9001-certified facility using precision winding, automated gear assembly and controlled bearing press-fit processes. Raw materials are sourced from certified suppliers and undergo incoming inspection for conductor grade, gear hardness and housing dimensions.
Each motor is assembled on precision lines and then tested for no-load speed, current draw, torque output and insulation resistance. The output shaft is checked for run-out, and the mounting holes are verified against the OEM gauge. Every unit runs through a loaded break-in cycle before packing.
Random samples from each production batch undergo environmental testing, including thermal cycling, humidity exposure, vibration and dust ingress, to validate long-term reliability in heavy-duty truck applications. These tests ensure the motor continues to perform in the harsh conditions experienced by SINOTRUK Howo vehicles.
