A 15798062 trunk release switch may look like a simple replacement, but the printed reference number is only the first fitment check. Connector shape, pin count, button layout, housing, mounting position, and the location on the vehicle all need to match the original part. NexuParts lists this aftermarket switch with references 15798062 and 22863048 for Chevrolet vehicles, without claiming a universal model-and-year range.
This guide focuses on the checks a buyer can complete before ordering. It does not replace a VIN-specific parts catalog or the information on the original switch. The safest decision comes from comparing the old part and the product photos point by point.
What the 15798062 / 22863048 Trunk Release Switch Is
The listed product is one new aftermarket trunk or tailgate release switch. Its product references are 15798062 and 22863048, and its Shopify SKU is SD-15798062-794952297901. The listing identifies Chevrolet compatibility at the brand level, but it does not provide a verified model, model-year, or trim chart.
Review the current photos, price, inventory, and supplied configuration on the 15798062 / 22863048 Chevrolet trunk release switch product page. Use the live product record as the source for what is currently offered, and compare it with the switch removed from your vehicle.
Why the OE Reference Alone Is Not Enough
An OE-style number is a strong starting point because it narrows the search to a specific part family. It still should not be used in isolation. Vehicle manufacturers can use different connectors, housings, or mounting details across trims, production dates, body styles, and markets. A number may also be incomplete, worn, or associated with a larger assembly rather than the individual switch.
For that reason, confirm both 15798062 and 22863048 against a trusted vehicle-specific catalog or the original component. Then compare the visible physical details. If the number agrees but the plug, pins, or mounting geometry differs, pause and resolve the discrepancy before buying.
15798062 Trunk Release Switch Fitment Checklist
1. Read the complete number on the original part
Remove or inspect the existing switch only if you can do so safely and without damaging surrounding trim. Photograph every label and molded marking before cleaning the part. Compare the complete reference with 15798062 and 22863048, including every digit. Do not rely on a partial number or a marketplace title copied from another listing.
2. Compare the electrical connector
Study the product images and your original plug from the same angle. Check the connector outline, latch position, keying grooves, pin count, pin arrangement, and the direction in which the harness enters. A plug that appears close but requires force, trimming, or an adapter should be treated as a mismatch unless a reliable catalog explicitly documents otherwise.
3. Match the button and housing
Compare the button face, its shape and travel area, the outer housing profile, edge contours, and any locating tabs. The visible button may be similar across several switches even when the hidden housing differs. Product photos are especially useful here: compare the front, rear, and side views rather than judging by the first image alone.
4. Verify the mounting method and position
Confirm where the switch sits on your vehicle and how it is retained. Look for tabs, clips, screw points, or molded shoulders on the original. Note the orientation of the connector after installation. A physically reversed or differently keyed housing can prevent proper seating even when the external button looks correct.
5. Confirm the vehicle details independently
Record the VIN, model, production year, trim, body style, and market. Use those details with a Chevrolet dealer catalog or another dependable fitment source. The NexuParts listing identifies the Chevrolet brand but intentionally does not invent a broad fitment table. Brand compatibility by itself is not proof that the switch fits every Chevrolet vehicle.
Symptoms to Check Before Ordering a Switch
A release that does not respond can make the switch a reasonable item to inspect, but the symptom alone does not diagnose the failed component. First check whether the problem is intermittent or constant and whether any other release control works. Inspect the original switch and connector for visible damage, looseness, moisture, or corrosion without bypassing safety procedures.
The vehicle may also have wiring, latch, actuator, control-module, power-supply, or mechanical issues. A replacement switch cannot correct a fault elsewhere in the circuit. If testing the system requires electrical measurements, trim removal, or powered-latch operation, use the correct service information or ask a qualified technician to diagnose it.
Questions to Answer Before Checkout
- Does the original part show 15798062, 22863048, or a catalog-confirmed replacement reference?
- Does the connector shape and latch position match the product photos?
- Is the pin count and pin arrangement identical?
- Do the button layout, housing profile, clips, and mounting points agree?
- Is the switch installed in the same rear trunk or tailgate location?
- Have the VIN, model, year, trim, body style, and market been checked independently?
- Has a switch fault been distinguished from a wiring, latch, actuator, or power problem?
Save clear photos of the original switch, connector, and surrounding mounting area. Those images make it easier to compare details and explain a fitment question before the package is opened or installation begins.
Do Not Substitute a Similar-Looking Switch
Release switches from different vehicle brands can look broadly similar but are not automatically interchangeable. For example, NexuParts also carries a 3M51-19B514-AC rear release switch listed for Ford vehicles. That separate listing is useful as a reminder that similar function does not establish shared fitment. Match the exact reference, connector, housing, and vehicle application rather than choosing by appearance.
You can browse the broader NexuParts auto lighting and electrical collection for other vehicle electrical parts, while treating every product as its own fitment decision.
Frequently Asked Questions
Does 15798062 guarantee fitment?
No. It is a valuable reference, but fitment should also be verified by VIN-specific catalog information and a physical comparison of the original switch, plug, pins, housing, and mounting position.
Are 15798062 and 22863048 interchangeable?
The NexuParts product record associates both references with this one listed switch. That does not prove interchangeability for every vehicle. Confirm the applicable replacement chain for your exact VIN and original part.
Can a new switch fix a trunk that will not open?
Only if the switch is the failed component. Wiring, power, latch, actuator, control, and mechanical faults can create a similar symptom. Diagnose the circuit before replacing parts when the cause is uncertain.
What should I compare in the product photos?
Compare the connector outline, latch, keying, pins, button face, housing contours, clips, mounting points, and orientation. Use multiple image angles and place the original part beside the screen when possible.
Make the Final Fitment Decision
Before ordering a 15798062 trunk release switch, confirm the complete reference and the vehicle details, then match the connector, pins, button layout, housing, mounting method, and rear location. If every check agrees, revisit the Chevrolet 15798062 / 22863048 trunk release switch listing for the current offer. If any detail remains uncertain, resolve it with VIN-specific documentation rather than assuming that a close visual match will fit.
