A 3M51-19B514-AC trunk switch search is most useful when you already have the reference from your original component. NexuParts lists this item as an aftermarket trunk release switch for Ford vehicles. Before ordering, check the full number, connector, housing, and mounting details together. The product description does not supply a complete model and year application table, so a Ford badge or a similar photograph should not be the final basis for your choice.
3M51-19B514-AC trunk switch: identify the item first
The 3M51-19B514-AC Ford trunk release switch is described as a replacement control for trunk or tailgate release. Its stated package contains one trunk release switch. The page identifies it as an aftermarket part rather than an official brand product. That distinction matters if you are specifically seeking a genuine manufacturer-branded component.
The store SKU is SD-3M5119B514AC-820236558189. Use it to identify this store item when contacting support, but do not confuse the full SKU with the original part reference. For the compatibility comparison, record 3M51-19B514-AC exactly. The long catalog number appearing in a link or SKU is not an additional confirmed manufacturer reference in this guide.
What your release-control symptom can and cannot establish
You may be researching a switch after noticing intermittent response, no response from the release control, or visible damage to an existing control. The listing discusses control-response problems as possible concerns, but those observations do not diagnose the cause on your vehicle. A replacement listing cannot determine whether the switch itself needs replacement.
Keep the repair question separate from the buying question. If the fault has not been identified, seek appropriate professional diagnosis before choosing a component. Once you know which part you need, the checklist below helps organize the fitment comparison. It is not an electrical test procedure and does not promise that installing this switch will fix any particular symptom.
Use a purchase checklist with clear stopping points
Full reference: matched or unresolved?
Read the original marking carefully, including the final AC suffix. Take a legible photograph if the reference is difficult to transcribe. A partial number, such as the middle section alone, is not enough to confirm this item. If your original has a different suffix, stop and ask about that difference. This page does not establish a list of interchangeable variants or manufacturer supersessions.
When a character is unreadable, label it as unreadable in your inquiry rather than completing the number from memory. Include the original photograph and the product link. This avoids turning an uncertain observation into an apparent exact match that another person might reasonably rely on.
Connector: compared from the correct side?
Compare the connector outline, orientation, retaining features, and terminal arrangement with the listing photographs. The product description asks buyers to check pin count but does not state a numeric count. Do not borrow a pin specification from a neighboring listing. If the necessary view is missing, request confirmation before purchase rather than assuming the connector can be adapted.
Housing and mounting: a complete comparison?
Review the housing shape and attachment points, not just the visible button surface. Record the installation position of your original control and compare its mounting details with the product page. The description directs you to match the original position; it does not provide a detailed installation-location specification. Avoid deriving that specification from shorthand in a URL.
Vehicle details: documented rather than guessed?
Have your vehicle model, year, trim, and original reference ready when requesting fitment help. The reviewed title and description identify Ford vehicles without a complete model-year table. This guide therefore does not add a specific model or year range. A search result containing a model name should not replace a confirmed application check for your individual vehicle.
Understand what you are ordering
The package description is for one switch. It does not list a complete latch assembly, wiring kit, or additional installation hardware. If your repair requires another component as well, confirm that separately. Do not assume that the broad phrase “trunk release” means the item includes every part involved in releasing or opening the trunk.
Review the current listing for price, availability, and purchase terms before checkout. Keep any fitment clarification with your order record. This guide does not provide a delivery promise, waterproof rating, or installation-time estimate, because those claims are not established by the reviewed product details.
Similar function does not mean the same application
The Lighting & Electrical parts collection includes other release controls. Category browsing is useful when locating a reference, but the product type alone is not a compatibility test. A control can serve a similar purpose while belonging to a different vehicle application.
For comparison, the 15798062 / 22863048 Chevrolet trunk release switch is a separate listing with different references and a Chevrolet application. It is not presented here as an alternative for the Ford part. If several release switches appear in your search, compare their exact references rather than selecting by price or general appearance alone.
Make a useful fitment inquiry
Send the product link, complete original reference, vehicle details, and clear photographs of the connector and mounting features. Describe the specific uncertainty: a different suffix, an unclear connection, or a housing feature you cannot compare. Provide your VIN through the store's fitment-help contact channel when vehicle-specific clarification is needed. A precise question gives support a concrete detail to investigate.
Frequently asked questions
Is this an official Ford part?
The product page describes an aftermarket replacement, not an official brand product. Ford is used to describe the listed compatibility context. Matching a reference does not establish genuine-brand manufacture.
Does the listing confirm every Ford model?
No universal application is established. Confirm the original reference and physical configuration for your vehicle, and ask about missing model-year information before ordering.
What if the received item differs from my original?
Compare it with your saved photographs before installation. If the connector, housing, or mounting features differ, contact the store before modifying or fitting it. This guide does not prescribe removal steps or wiring changes.
Order only after the open questions are resolved
Return to the 3M51-19B514-AC replacement switch page with your checklist ready. A 3M51-19B514-AC trunk switch purchase should follow a documented reference and physical match, not a guess based on the vehicle brand. Resolve uncertain details first, then review the current listing before placing your order.
