Product Details
ISUZU power window regulator motor
,24V copper-core window motor
,NPR 4HG1 window regulator motor
The Front Door Power Window Regulator Motor with OEM numbers 8-98058430-0 / 8980584300 is a verified direct-fit replacement for ISUZU NMR, VC46, 700P, NPR, NQR, NLR, FSR, and FVR trucks equipped with 4HG1, 6UZ1, and 6HK1 diesel engines. Mounted on the window regulator assembly inside the front door trim panel, this motor (MOTOR; POWER WINDOW REG, FRT DOOR) drives the regulator mechanism through internal gear sets to raise and lower the window glass smoothly. It is a core actuation component of the cab's electric comfort system.
The motor features a 24V DC design (some models use 12V versions — confirm before ordering), with high-efficiency copper-core windings and a reinforced internal gear set for high torque output and consistent lifting speed. The housing combines high-strength plastic with an aluminum shell, offering moisture, dust, and heat resistance for the high-frequency demands of heavy commercial trucks. Manufactured to OEM standard dimensions with a standard multi-pin connector for plug-and-play installation without door harness modification.

When the front door power window regulator motor exhibits the following conditions, timely inspection and replacement are required:
- Window fails to move or moves very slowly: Worn internal brushes or aged windings reduce output torque, causing slow or no window movement.
- Abnormal noise during operation (clicking or gear grinding): Worn or broken internal gears cause the motor to spin without effectively driving the regulator mechanism.
- Window operates in one direction only (up but not down, or vice versa): Internal commutator or control module failure disables one-directional operation.
- Motor runs but window does not move: Motor output shaft slips against the regulator gear, or the regulator mechanism itself is seized while the motor spins freely.
- Motor overheats or fuse blows repeatedly: Internal short circuit or seizure causes excessive current draw, triggering protection or blowing the fuse.

⚠️ Important — Confirm Before Ordering:
LH/RH Confirmation: Supplier listings vary on mounting position: some specify LH (Left-Hand / Driver Side), while others specify RH (Right-Hand / Passenger Side). Confirm the required side against your vehicle configuration, or provide a photo of the original door motor mounting position before ordering.
Voltage Confirmation: This motor is available in 24V and 12V versions (depending on model configuration). Heavy trucks (e.g., 700P, NPR, NQR) typically use 24V systems. Verify original vehicle electrical system voltage before ordering.
Model Confirmation: This motor fits NMR, VC46, 700P, NPR, NQR, NLR, FSR, FVR and other model series. Variations may exist across model years or cab configurations. Verify original motor number before installation.
Pre-Installation Verification: Please provide VIN or original window motor number for precise fitment confirmation.

⚠️ Important: Front door window motor installation involves door trim removal and electrical connection. Professional installation by a qualified technician is recommended. Disconnect the negative battery terminal before installation and protect clips and wiring when removing the door trim. After installation, repeatedly test window lifting smoothness, speed, and stop positions to confirm no binding or abnormal noise.
- Disconnect power: Disconnect the negative battery terminal to prevent electrical short circuits.
- Remove door trim: Carefully remove the front door trim panel, release clips, and disconnect power window switch harness connectors.
- Remove old motor: Remove motor fixing bolts (typically 2–3), unplug the motor harness connector, and detach the old motor from the regulator assembly.
- Install new motor: Align the new motor with the regulator mounting position, hand-thread the fixing bolts first, confirm the motor output shaft correctly engages the regulator gear, then tighten to the specified torque.
- Connect harness: Plug in the motor harness connector, confirming the clip engages.
- Function test: Restore battery connection and repeatedly operate the window switch, testing smooth lifting, correct speed, and accurate stop positions without abnormal noise or binding.
- Reinstall door trim: After confirming correct function, reinstall the door trim panel and connect the switch harness.
- Every 12 months: Check window lifting smoothness, clean dust inside the door trim, and inspect the motor connector for corrosion.
- When window lifting slows or abnormal noise is detected: Inspect motor and regulator condition promptly to prevent motor burnout from overload.
- Keep window guides clean and lubricated: Periodically clean glass guides and apply appropriate grease to reduce motor load.
