A 12450256 seat switch purchase should begin with the original part reference, not just the vehicle badge. NexuParts lists this aftermarket seat adjustment switch for Chevrolet and Cadillac vehicles. The listing identifies the replacement category and reference, but it does not provide a complete model-year application table. Use this guide to build a comparison record, separate confirmed details from unanswered questions, and decide what to verify before placing your order.
12450256 seat switch: what is actually listed?
The 12450256 Chevrolet Cadillac seat adjustment switch is described as a new aftermarket replacement for electric seat adjustment control. Its package description states one seat adjustment switch. It is not presented as an official brand product, a complete seat assembly, or a replacement motor. Keep the stated component separate from the larger system when planning your purchase.
The store SKU is SD-12450256-817492167159. That identifies the catalog item for an order or support request. The reference to compare with your original component is 12450256. Do not interpret the longer numeric sequence in the store identifier as another verified manufacturer reference. Include the product link in any inquiry so support can see the exact item under discussion.
Identify the repair need before selecting the replacement
You may start researching a switch because an adjustment control responds intermittently, does not respond, or has visible damage. The product page discusses control-response concerns as possible symptoms, but those observations do not establish the cause on your particular vehicle. A replacement listing is not a diagnosis, and an apparent symptom match does not prove that this switch is the correct repair.
If the cause is uncertain, obtain appropriate professional advice before buying parts. Keep your description factual: which control you used, what you observed, and whether the component is visibly damaged. This buying guide does not supply electrical testing instructions, seat removal steps, or a promise that replacing the switch will solve a specific problem.
Prepare a comparison record with four sections
Original reference and vehicle information
Write down the entire reference from your original component, including any letters or suffixes. Photograph an unclear marking instead of filling in missing characters from a search result. Record the vehicle year, model, trim, and the location of the switch you need. The reviewed title and description name Chevrolet and Cadillac, but they do not establish which individual model-year combinations use this item.
If the original reference differs from 12450256, leave that as an unresolved question. This guide does not establish alternate numbers or a supersession chain. Similar digits and a familiar housing are reasons to investigate further, not a basis for assuming interchangeability.
Connector and terminal arrangement
Compare the original connector's outline, orientation, retaining features, and terminal arrangement with the listing photographs. The description asks buyers to verify pin count, but does not state a numeric pin count for this item. Do not import that specification from another seat switch. If a necessary connector view is missing, request clarification before ordering.
Document any difference explicitly. A connector that looks similar from one angle may still leave an important detail unresolved. This guide does not authorize adapting a plug, changing wiring, or modifying the replacement to make an uncertain match work.
Control layout and housing
Compare the visible controls, their arrangement, and the shape of the housing. Look at the underside as well as the outward-facing surface. Do not assume a particular number of adjustment directions or a memory-related function, because the reviewed description does not specify those capabilities. Ask about the controls you actually need rather than relying on the general phrase “seat adjustment.”
Mounting details and installation position
The product description instructs buyers to match the original mounting position. Compare attachment features, clips, and housing details with your original component. Do not infer a complete side or position specification from an old URL label. Record the position on your vehicle and seek explicit confirmation if the current listing does not settle the question.
Do not confuse two Chevrolet Cadillac seat-switch listings
NexuParts also carries a 25974715 Chevrolet Cadillac seat adjustment switch. It shares the general part category and brand context, but its reference is different. This guide does not establish that 25974715 and 12450256 are interchangeable. Treat them as separate candidates until your original reference and application information identify the appropriate item.
If your original marking reads 25974715, review that listing's own details rather than transferring assumptions from this page. The All Auto Parts & Accessories collection offers a broader route to browse parts, but category membership is not fitment evidence. Narrow your choice using the original reference and physical comparison.
Send a question that resolves the missing detail
A useful fitment request includes the vehicle information, full original reference, exact product link, and clear photographs of the controls, connector, and mounting features. State the detail you cannot verify. For example, describe an unreadable suffix or a housing feature that differs from the image. Provide your VIN through the store's fitment-help contact channel when vehicle-specific assistance is needed.
Keep the response with your purchase notes. Do not turn an unanswered question into a confirmed match simply because the other details appear similar. If the information remains incomplete, resolve it before checkout rather than planning to modify the item after delivery.
Frequently asked questions
Is the switch genuine Chevrolet or Cadillac?
The listing describes an aftermarket replacement, not an official brand product. The vehicle names describe the stated compatibility context and do not identify the manufacturer of the replacement.
Does one switch fit every model from these brands?
No universal application is established. The original reference, connector, control layout, mounting details, and vehicle-specific information still need to agree. A brand name alone cannot finish the check.
What is included?
The stated package contains one seat adjustment switch. Do not assume that separate trim, motors, wiring, or installation hardware are included unless the current product page expressly lists them.
What should I check after delivery?
Compare the received item with your original component and saved photographs before installation. Contact the store if the reference, connector, or housing details differ. Review current purchase and return terms before fitting or modifying an electrical component.
