Electric Window Regulator 8980098113 8-98009-811-3 For ISUZU D-MAX 1 (8DH) TFS77 TFS85 TFS54 TFS86 (2003–2012) — Front Left (LH), Power Window, Without Motor

The Electric Window Regulator with OEM references 8980098113 / 8-98009-811-3 (and related cross-references 8-98009-811-0 / 8-98009-811-2 / 8-97350-002-0) is a verified replacement for the front left (LH) door of the ISUZU D-MAX 1 (8DH, 2003–2012) pickup. This is the power window version — the mechanical lifting mechanism that raises and lowers the door glass when driven by the electric window motor.

This regulator is specifically for the front left (LH) door — the driver side in LHD markets and the passenger side in RHD markets. It is not interchangeable with the front right (RH) unit, which uses the 8-98009-810-x family, nor with any rear door regulator (e.g., 8-98150-525-0 / 8-98150-526-0).

The part is confirmed across TFS77 (3.0 TD e3, 2003–2006), TFS85 (3.0 TD e4, 2007–2012), TFS54 (2.5 TD e3, 2003–2006), and TFS86 (2.5 TD e4, 2007–2012) chassis for the D-MAX 1 (8DH) platform. It is available as an OEM genuine ISUZU part (reference price ~€79.39 ex-tax via parts-isuzu.com) and as OEM-grade aftermarket from multiple European and Asian suppliers.

• Position & Door Verified: Front Left (LH) — confirmed by Euro4x4parts ("Front — Left side — Power window version — Without motor") and DLJ Auto Parts ("ISUZU D-MAX (8DH) | FRONT LH | 8-98009-811-0 / 8-98009-811-2 / 8-98009-811-3 / 8-97350-002-0").
• Drive Type Verified: Power window (electric) — confirmed by Euro4x4parts ("Power window version") and multiple Turkish suppliers listing the part under "CAM KRIKOSU ON ELEKTRIKLI MOTORLU 12V SOL" (front electric window regulator with motor, 12V, left).
• Motor Inclusion Verified: Without motor — Euro4x4parts English listing explicitly states "Without motor"; Spanish listing states "Sin motor". The motor must be ordered separately if a complete assembly is required.
• Vehicle & Engine Coverage Verified: ISUZU D-MAX 1 (8DH) 2003–2012, covering TFS77 (3.0 TD e3, 131 bhp, 07/2003–09/2006), TFS85 (3.0 TD e4, 163 bhp, 10/2006–05/2012), TFS54 (2.5 TD e3, 100 hp, 07/2003–09/2006), and TFS86 (2.5 TD e4, 136 bhp, 10/2006–05/2012) — confirmed by Euro4x4parts fitment data.
• Cross-Reference Density Verified: 8980098113, 8-98009-811-3, 8-98009-811-0, 8-98009-811-2, 8-97350-002-0 are consistently grouped as equivalent references across Euro4x4parts, DLJ, and parts-isuzu. Turkish aftermarket cross-reference IZ35-E020B is confirmed for the same application.
• OEM Genuine Availability Verified: parts-isuzu.com lists 8980098113 as a genuine ISUZU "REGULATOR ASM" with the statement "exactly the same as the one mounted at the factory when the vehicle was new".
• Net Weight / Dimensions Not Publicly Published for This Exact Part Number: Public supplier listings for 8980098113 do not publish net weight or external dimensions for the regulator assembly. Confirm these specifications at inquiry for logistics and packaging planning.

• Window does not move when switch is pressed: The regulator cable, sector gear, or lifting arm has failed, preventing the motor from transferring motion to the glass — the most common failure mode on aging D-MAX power windows.
• Window moves slowly or binds: A worn or dry regulator track, a frayed cable, or a bent lifting arm increases resistance, causing slow or jerky operation.
• Grinding, clicking, or snapping noise from inside the door: A stripped sector gear or a broken cable strand produces audible mechanical noise during window operation.
• Window glass drops suddenly or will not stay up: A failed regulator arm or cable allows the glass to fall under its own weight, even with a functional motor.
• Window tilts or tracks crookedly: A bent regulator arm or worn guide roller causes the glass to cock in the run channel as it travels.
• Motor runs but glass does not move: The motor is functioning but the regulator mechanism has disconnected from the glass carrier or the cable has failed.

• Position is the first and most critical check: This regulator is for the front left (LH) door. The front right (RH) uses the 8-98009-810-x family (8-98009-810-0 / -2 / -3), and rear doors use entirely different references (8-98150-525-0 / 8-98150-526-0). Do not interchange LH, RH, front, or rear regulators.
• Motor is not included: This is the regulator assembly without motor. If the original vehicle's motor is functioning, it can be transferred to the new regulator. If a new motor is also required, order the motor separately (reference 8-98009-802-0). Confirm the motor connector and mounting configuration match the replacement regulator before installation.
• Power vs. manual: This is the power window version. Manual window regulators for the D-MAX 1 use different part numbers and are not interchangeable.
• Model year / chassis boundary: The confirmed coverage is D-MAX 1 (8DH), 2003–2012. The D-MAX 2 (2012+) uses a different window regulator family (8-98093-551-x / 8-98209-994-x for front RH, etc.). Do not assume interchangeability across D-MAX generations.

1. Confirm the required part first: Verify that the original regulator is power (electric) and is the front left unit. Confirm whether the original motor is to be reused or a new motor is required.
2. Remove the door trim panel: Use a plastic trim tool to release the perimeter clips. Disconnect the power window switch connector.
3. Remove the water shield / moisture barrier: Carefully peel back the plastic moisture barrier to access the regulator mechanism. Do not tear it — it must be reseated during reassembly.
4. Remove the glass: Lower the window until the glass-to-regulator attachment bolts are visible through the access holes. Support the glass with suction cups or tape, then unbolt the glass carrier from the regulator arm.
5. Remove the motor (if reusing): Unbolt the motor from the old regulator. Note the motor orientation and connector position for transfer to the new regulator.
6. Remove the old regulator: Unbolt the regulator from the door inner panel. Guide the regulator arm out through the largest access opening.
7. Transfer the motor to the new regulator: Mount the motor onto the 8980098113 regulator. Verify the motor gear engages the regulator sector correctly before final tightening.
8. Install the new regulator: Position the regulator in the door and secure the mounting bolts. Do not fully tighten until the glass is aligned.
9. Reattach the glass: Bolt the glass carrier to the new regulator arm. Check glass alignment in the run channel before final tightening.
10. Test operation: Operate the window through its full travel range using the switch. Confirm smooth operation, correct glass tracking, and no binding or unusual noise.
11. Reseal the moisture barrier and reinstall trim: Reseat the moisture barrier with butyl tape or sealant. Reinstall the door trim panel and switch.
12. Road test: Drive the vehicle and listen for rattles or wind noise from the door. Verify that the window remains in position over bumps.

• Lubricate the window run channel every 1–2 years with silicone spray — a dry channel increases regulator load and accelerates wear.
• Inspect the regulator cable / sector gear if window operation becomes slow or noisy — early detection prevents complete failure.
• Avoid operating the window when the glass is frozen — forcing a frozen regulator can strip the sector gear or break the cable.
• Check the motor mounting bolts for tightness if the window rattles or operates intermittently.

• Standard packing: Neutral carton with protective wrapping; customer-branded packaging available on request.
• Package contents: 1 × Electric Window Regulator Assembly (Front Left, without motor). Motor, mounting bolts, and glass carrier hardware are not included unless explicitly stated — confirm exact package contents at inquiry.
• Set options: Regulator only (standard for this reference) / regulator + motor combination (subject to separate motor supply) — specify at inquiry.
• Suitable for: ISUZU D-MAX 1 (8DH) interior and window repair shops, pickup fleet maintenance departments, spare parts distributors, and export wholesalers serving Southeast Asia, the Middle East, Africa, Latin America, and Europe.
