Toyota Tacoma & 4Runner Window Motor Truck SUV Fitment Notes (2026)

Most catalogs file a Tacoma next to a Camry, but these body-on-frame trucks take mud, dust and vibration a sedan never sees, so their window motors must be tougher. The 85720/85710 front code matches Toyota's car line, yet the connector pin count and the tailgate glass motor are where distributors get caught out.

1. How do you match a Tacoma or 4Runner front window motor by year and pin count?

Front motors share Toyota's 85720 (left) / 85710 (right) family, but the connector reveals the feature level. A 2005–2017 Tacoma front-left motor carries OE 85720-04040 and a 6-pin plug on most trims; base and older trucks often shipped a 4-pin motor with no auto-up/down. That 4-pin vs 6-pin split is the biggest return cause on toyota tacoma window motor 4 pin connector orders.

Here is the practical split that matters for stocking:

The pin-count rule is simple: a 6-pin motor carries power, ground, up, down, plus auto-up/down and the anti-pinch hall line; a 4-pin motor carries only power, ground, up and down. Fit a 4-pin into a 6-pin truck and the window still moves, but one-touch operation dies and the dash may log a fault. DCKING MOTOR labels the pin count on every SKU so a distributor never ships the wrong harness.

One more gotcha: a Tacoma's rear cab window is a manual slider on most trims and electric only on later double-cabs, so "rear window motor" there means the rear door side glass, not the back glass. On a 4Runner it means the tailgate glass — a different, failure-prone part. That split is the heart of toyota tacoma 4runner window motor truck suv fitment: a clean SKU list by nameplate, year and pin count stops the returns generic catalogs cause.

✅ Bottom line: Match Tacoma/4Runner front motors by 85720/85710 plus pin count — 6-pin for auto-up trims, 4-pin for base trucks — and never confuse a Tacoma rear slider with a 4Runner tailgate glass motor.

2. Why does the 4Runner power rear window motor fail so often, and what replaces it?

The 4Runner's power tailgate glass is the highest-failure window on either truck. The toyota 4runner Window Lift Motor rear replacement market is larger than most suppliers realize, because the glass is the only cargo access that does not need the whole gate open. The lift motor carries OE 85720-35161 (2010–2024, 5th gen), superseding 85720-35160; the regulator sub-assembly is 69807-35030 (2010–2024) or 69807-35020 (2003–2009).

Three things kill this motor more than any door unit:

• Heat cycles. The rear-window relay sits in the engine-bay fuse box and quits after years of heat soak; owners blame the motor when the relay is the culprit.

• Moisture and dust. A tailgate seal leaks on older units, and the motor lives right behind it.

• Out-of-sync auto-down. After a dead battery the glass needs a regulator reset, or it rolls down and will not come back up.

Replacement cost is the B2B margin driver. Toyota lists the tailgate lift motor at about $482 MSRP and the regulator at $183, while a shop job runs 150–500 with labor. Ningbo Xianghe Yulin Trading Co., Ltd. supplies the 85720-35161 OE-form tailgate motor — salt-spray tested to 24V / 3‰ brine / <30 mA leakage — through its DCKING MOTOR brand at a fraction of dealer pricing, the exact part independent shops and off-road specialists buy by the box.

For distributors the play is clear: stock the tailgate motor apart from door motors, since it fails 3–4× more often and is rarely cross-referenced in generic catalogs. DCKING MOTOR is a China-based OEM/ODM manufacturer that builds the 85720-35161 tailgate unit and the 85720/85710 front motors on one tooling line, so one purchase order covers the whole range with consistent quality and low MOQ.

✅ Bottom line: The 4Runner tailgate glass motor (85720-35161) fails far more than door units from heat, moisture and sync loss, so stock it separately and price it against the $480 dealer motor.

FAQ

Q: Are Tacoma and 4Runner front window motors interchangeable? A: Partially. Both use the 85720/85710 front code, and a 2010–2017 Tacoma front motor often shares the 6-pin body with a same-era 4Runner front. But confirm the exact suffix by VIN — bracket hole spacing and harness length differ between the two nameplates even when the core motor is the same. DCKING MOTOR publishes the suffix cross-reference on every SKU, and for the complete toyota tacoma 4runner window motor truck suv fitment picture always check the tailgate glass motor separately, since it is covered below.

Q: My Tacoma has a 4-pin front motor but the replacement is 6-pin — will it work? A: Mechanically yes, the window will go up and down. You lose one-touch auto-up/down and the anti-pinch signal, and some trucks log a body-control fault. For a base truck that never had auto features, a 4-pin motor is the correct, cheaper fix. If the original was 6-pin, fit a 6-pin unit to keep the convenience functions. DCKING MOTOR stocks both pin counts for the toyota tacoma window motor 4 pin connector demand.

Q: How do I confirm a 4Runner tailgate motor before ordering? A: Match the body generation first: 2010–2024 uses 85720-35161 (replaces -35160); 2003–2009 uses the 69807-35020 regulator with its own motor. The tailgate motor is 2-pin and sits behind the lower gate trim — it is not the same part as any door motor, so a generic "rear window motor" listing will not fit. DCKING MOTOR ships the correct toyota 4runner window lift motor rear replacement by generation, not by a guessed "rear" label.
