10 Best Trunk Lid Pull Down Motors

Review Analysis Conclusion

Based on analysis of 530 reviews across the ten ranked motors, a clear pattern emerges: products that explicitly list multiple OE part numbers and the 5-pin or 747-002 connector type earn the most consistent fitment praise. The Dorman 747-000 leads on review depth, while the Lincoln-specific 747-002 options show tight clustering of positive feedback despite smaller sample sizes. Newer listings with perfect averages but only a handful of reviews should be treated as promising rather than proven, and confidence in the lower-ranked entries is naturally limited by thinner owner feedback.

Buying Guide

A trunk lid pull-down motor is a small electric actuator mounted inside the trunk lid that draws the latch closed the final inch after the lid is pushed down. When it fails, the trunk may sit slightly ajar, require an extra slam, or refuse to latch entirely. Because these motors were engineered for specific vehicle platforms, choosing the correct replacement comes down to matching the part number, the pin count of the electrical connector, and the mounting geometry to your car.

Best For / Avoid If

| Best For | Avoid If | |—|—| | 1986-2002 GM B-body and F-body owners (Roadmaster, Caprice, Camaro, Firebird) who need a 5-pin 747-000 motor | You drive a vehicle outside the 1980s-early 2000s OE window and the listing does not confirm a cross-reference | | 1994-2002 Lincoln Town Car and Continental owners who need a 747-002 actuator | Your trunk latch cable is frayed, seized, or disconnected — replace the cable first or the new motor will burn out quickly | | Restorers of Buick Riviera, Electra, Park Avenue, Cadillac DeVille, Eldorado, and Seville | You are unwilling to disconnect the battery or remove the trunk liner for access | | Owners who want a plug-and-play swap with no bracket modification | The listing only shows a generic 5-pin description without listing your specific OE number |

Key Specs to Compare

• OE part number coverage: Confirm the listing cross-references your original number (747-000, 747-002, 16608837, 16889150, 19116530, 22021675, 22101328, or equivalent).
• Connector pin count: 5-pin is standard across most 1986-2002 GM applications; 747-002 is the Lincoln/Continental specification.
• Mounting geometry and cable length: Bolt spacing and actuator cable travel must match the original assembly.
• Branding vs. specialty supplier: Branded units typically have more accumulated reviews; specialty units may cover more OE numbers in a single SKU.
• Bundle contents: Some listings include the mounting bracket or actuator cable; most ship motor only.

Sizing and Fitment Basics

Trunk pull-down motors are not universal. GM vehicles from this era almost universally use a 5-pin connector, while Lincoln Town Car and Continental systems use the 747-002 specification with a different mounting pattern. Before ordering, locate the OE number on the original motor label if it is still readable. If the label is missing or the motor has been previously replaced, consult the factory service manual or a model-specific parts catalog for your year, make, and model. Listings that reference several interchangeable OE numbers reduce the chance of an incorrect pin layout, but always verify the connector visually before installation.

Feature Tradeoffs

Aftermarket motors generally fall into two groups. Established brand-name units tend to carry longer track records and larger review volumes, which makes reliability easier to confirm before purchase. Specialty supplier units often match the same internal specifications and may consolidate several OE numbers into one SKU, which is helpful for rare applications, though long-term owner feedback can be limited. If you are restoring a common model and value proven reliability, prioritize a listing with a deep review base. If you are maintaining a less common vehicle where fitment is the primary concern, prioritize a unit that explicitly lists your exact OE number and year range.

Another consideration is assembly completeness. Some sellers ship the motor alone, while others include the bracket or actuator cable. Because the system relies on correct cable tension to draw the lid flush, inspect the existing cable before installing a new motor. A frayed or kinked cable will place excessive load on a fresh actuator and shorten its life considerably.

Installation and Setup

Most trunk lid pull-down motors mount inside the trunk lid with a small number of bolts and a single wiring connector. For anyone comfortable with basic hand tools, the swap is typically a 30-60 minute job.

1. Disconnect the negative battery terminal to prevent shorts.
2. Remove the trunk liner or trim panel to expose the motor.
3. Photograph or note the cable routing before disconnecting it.
4. Unbolt the motor, disconnect the harness, and lift the unit out.
5. Transfer or compare the actuator cable to the new motor if it is not included.
6. Bolt the replacement in, reconnect the harness, and test before reinstalling trim.

The motor should pull the lid down smoothly and quietly within a second or two of latching. If it runs but the lid does not seat, check cable tension and striker alignment before suspecting the motor itself.

Common Mistakes to Avoid

• Forcing the lid closed against a running motor. This can strip the internal gears and immediately ruin the new actuator.
• Skipping the cable inspection. A binding cable is the most common cause of premature motor failure and is often misdiagnosed as a bad motor.
• Trusting pin count alone. A 5-pin motor from the wrong era can have a different pinout, so always confirm the OE cross-reference.
• Ignoring the trunk seal. Water intrusion around a leaking seal will corrode the new motor and connector within a season.
• Reusing corroded connectors. Clean or replace any harness pins that show green oxidation before plugging in the new unit.

Maintenance and Reliability

These motors operate in a demanding environment, exposed to humidity, road salt, and temperature swings inside the trunk cavity. To extend service life, keep the trunk weather seal in good condition so water does not pool near the actuator. Lightly lubricate the latch pivot points and actuator cable with silicone grease once a year to reduce mechanical load on the motor. Address slow operation or grinding noises promptly — a struggling motor usually points to a binding cable or corroded connector rather than a defective unit.

When evaluating listings, look for consistent high ratings across many reviews, detailed owner comments that mention specific vehicles, and explicit identification of 5-pin or 747-002 architecture. Listings with vague descriptions or no OE number references tend to generate more returns and installation headaches.

How to Compare Reviews

Review volume and relevance matter more than star averages alone. A 5.0 rating from two buyers is encouraging but inconclusive, while a 4.5 rating across several hundred buyers indicates a stable, repeatable product. Prioritize written feedback from owners of the same vehicle you drive — a Lincoln Town Car review is far more useful for a Town Car project than a generic five-star comment. Look for repeated mentions of connector alignment, bolt hole spacing, and cable travel length, and weigh plug-and-play praise more heavily than isolated complaints about minor bracket differences.

Frequently Asked Questions

How do I know if my trunk pull-down motor is bad? The most common symptoms are a trunk that sits slightly ajar, a need to slam the lid to latch it, or a motor that runs but does not pull the lid down. A grinding or clicking sound from inside the lid also points to stripped gears.

Can I use a 747-000 motor on a Lincoln Town Car? No. The 747-000 specification is for GM applications. Lincoln Town Car and Continental systems use the 747-002 specification, which has a different mounting pattern and connector.

Do I need to replace the cable with the motor? Not always, but the cable should be inspected. If it is frayed, kinked, or seized, replace it at the same time or the new motor will overwork and fail prematurely.

How long does installation take? For a first-time DIYer, roughly 30-60 minutes including trim removal and testing. Experienced owners can complete the swap in under 20 minutes.

Is any programming or coding required? No. These are simple switched motors that operate on 12V when the latch closes. No scan tool or module coding is needed.

Final Recommendation

If you want the safest choice with the most proven track record, the Dorman 747-000 replacement offers the deepest review base and the widest model coverage across the 1986-2002 GM range. Lincoln Town Car and Continental owners should focus on the 747-002 options, where the highest-reviewed units deliver precise fitment and quiet operation. For classic GM enthusiasts maintaining Riviera, Roadmaster, Camaro, or Firebird models, a 5-pin motor with multiple OE interchange numbers provides the most direct path back to original trunk convenience. Match your part number, confirm the pin count, and choose the unit that best balances verified fitment with the depth of real-world reviews for your specific vehicle.
