Front Right Window Regulator 8-98111488-1 8-98005164-2 For ISUZU D-MAX TFR (2002–2011) — Power Window Type, Without Motor, Heavy-Duty Steel, Right Hand (RH)

The Front Right Window Regulator with OEM references 8-98111488-1 / 8-98005164-2 (condensed: 8981114881 / 8980051642) is a verified replacement for the front right-hand (RH) door of the ISUZU D-MAX (2002–2011) pickup platform. This mechanical lifting mechanism raises and lowers the door glass and is supplied as the power window type (without motor) — the electric motor is not included and must be reused from the original unit or ordered separately.

ISUZU's official parts catalog explicitly lists 8981114881 as "REGULATOR WIND / REGULATEUR; VITRE, PORTE AVANT — POSITION: R" (front door, right position). The same catalog lists the electric window motor as a separate line item (e.g., 8980098010, 8980098020), confirming that the regulator is supplied without the motor. Reference 8980051642 is also listed in the official catalog under the same front-right door section and is widely grouped with 8981114881 by aftermarket suppliers as a functionally interchangeable reference for this position.

• ✓Position Verified: Front Right (RH) — confirmed by the ISUZU official dealer parts catalog ("REGULATEUR; VITRE, PORTE AVANT — POSITION: R") for both 8981114881 and 8980051642. Ecer and Thai suppliers also list both numbers as "Front Door Window Regulator R".
• ✓Motor Inclusion Verified: Without motor — confirmed by ruishuoauto.com ("Product Type: Window Regulator (Motor not included)") and the ISUZU catalog structure, where regulator and motor are listed as separate line items.
• ✓Construction & Quality Verified: Reinforced industrial-grade steel with corrosion-resistant E-coating; 10,000+ cycle endurance tested, per ruishuoauto.com technical data.
• ✓Vehicle Coverage Verified: ISUZU D-MAX (2002–2011) — confirmed by the official catalog page for DMAX DOUBLE CAB 4X4 LONG (2004–2011). Pan Taiwan and Thai suppliers confirm D-MAX 2002–2012 coverage for the wider regulator family.
• ✓Cross-Reference Group Verified: 8-98111488-1 / 8981114881 / 8-98005164-2 / 8980051642 are consistently grouped as the front-right window regulator reference set across Ecer (NL/DE), Thai suppliers, and the official ISUZU catalog. 8-98111488-0 is confirmed as an alternate number.
• ✓Aftermarket Cross-Reference Lead: HU-IZ5301M-FR / HU-IZ5304M-FR (HUSHAN) style references appear for the D-MAX front window regulator family, useful for cross-checking against local supplier catalogs.
• ⚠Manual vs. Power Ambiguity for 8981114881: A Thai supplier (cnc789.com) describes 8981114881 as "แบบธรรมดา (Manual) / ใช้มือหมุน" (manual / hand-crank). This contradicts the official catalog's separation of regulator and motor and ruishuoauto.com's "power window system" description. The safest interpretation is that the regulator casting/arm assembly may be shared between manual and power applications, with the motor interface differing. Confirm the presence of a motor mounting provision on the original unit before ordering.

• Window does not move when the switch is operated: The regulator cable, sector gear, or lifting arm has failed, preventing the motor from transferring motion to the glass — the most common failure on aging D-MAX power windows.
• Window moves slowly, binds, or tilts in the track: A worn or dry regulator track, a frayed cable, or a bent lifting arm increases resistance and causes the glass to cock as it travels.
• 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.
• 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.

• Front Right (RH) only: This regulator is for the front right door. The front left (LH) uses a different reference (e.g., 8981114891 per the official catalog). Rear door regulators (e.g., 8-98005165-2 for rear left, 8-98005164-2 in some aftermarket listings for rear right manual) are not interchangeable.
• Motor is not included: This is the regulator assembly only. The original electric motor must be transferred, or a new motor ordered separately (reference 8980098010 / 8980098020). Confirm the motor mounting pattern and gear engagement before installation.
• 8-98005164-2 directory conflict: The official catalog lists 8980051642 under the front right section, while Pan Taiwan and European aftermarket sources list the same number as rear right manual. If the vehicle requires a front door regulator, prioritize 8-98111488-1; if a rear door manual regulator is needed, 8-98005164-2 is the likely reference. Confirm the required door position before ordering.
• D-MAX 2 (2012+) is different: The later D-MAX generation uses a different window regulator family (e.g., 8-98093551-1 / 8-98093554-1). Do not assume interchangeability across generations.

1. 1Confirm the required regulator first: Verify that the original unit is the front right regulator and that the vehicle is power window equipped. Check whether the original motor is to be reused.
2. 2Remove the door trim panel: Use a plastic trim tool to release the perimeter clips. Disconnect the power window switch connector.
3. 3Remove 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. 4Remove the glass: Lower the window until the glass-to-regulator attachment bolts are visible. Support the glass with suction cups or tape, then unbolt the glass carrier from the regulator arm.
5. 5Remove the motor (if reusing): Unbolt the motor from the old regulator. Note the motor orientation and connector position for transfer.
6. 6Remove the old regulator: Unbolt the regulator from the door inner panel. Guide the regulator arm out through the largest access opening.
7. 7Transfer the motor to the new regulator: Mount the motor onto the 8-98111488-1 regulator. Verify the motor gear engages the regulator sector correctly before final tightening.
8. 8Install the new regulator: Position the regulator in the door and secure the mounting bolts. Do not fully tighten until the glass is aligned.
9. 9Reattach the glass: Bolt the glass carrier to the new regulator arm. Check glass alignment in the run channel before final tightening.
10. 10Test operation: Operate the window through its full travel range using the switch. Confirm smooth operation, correct glass tracking, and no binding.
11. 11Reseal the moisture barrier and reinstall trim: Reseat the moisture barrier with butyl tape or sealant. Reinstall the door trim panel and switch.
12. 12Road test: Drive the vehicle and listen for rattles or wind noise. 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.
• 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.
• Package contents: 1 × Front Right Window Regulator Assembly (without motor). Motor, mounting bolts, and glass carrier hardware are not included unless explicitly stated.
• Set options: Regulator only (standard) / regulator + motor combination (subject to separate motor supply) — specify at inquiry.
