Picture this: Your Chevy Silverado's USB port stops working. You find a replacement online, the front looks identical, and the vehicle year matches. Easy fix, right?
Not so fast! You install the new part, only to discover that the connectors don't match. Or worse, your phone charges, but Apple CarPlay no longer works.
This is exactly why understanding the difference between GM USB port 13525889 and 13529873 matters. Both can appear in Chevrolet and GMC replacement-part searches, but they aren't interchangeable just because they look alike.
Here's how to spot the difference before spending your money.
13525889 vs 13529873: The Biggest Difference Is on the Back
Here's the simplest advice: Flip the USB module over!
The 13525889 version sold by JCarPart has one rear electrical connector. The three-connector version of 13529873 shown in our comparison uses a different rear connection arrangement.
That difference is more important than the front appearance. The number, shape, and position of the connections must match your vehicle's wiring.
| Feature | 13525889 | 13529873 |
|---|---|---|
| Rear connectors | 1 | 3 in the comparison version |
| GM part family | Dual charge-only receptacle | USB 2-port receptacle |
| Related service number | 13540949 | 13558185 |

What Is the GM 13525889 USB Port?
The 13525889 USB connector is a dual charging receptacle used in certain Chevrolet and GMC vehicle configurations, including selected Silverado and Sierra trucks.
It's designed for applications requiring the matching charging-only module. Depending on your truck's equipment, its original location may be different from the infotainment USB connection.
If your original module has one matching rear connector and your vehicle uses the charging-only configuration, this may be the replacement you're looking for.

What About GM Part Number 13529873?
The 13529873 USB receptacle belongs to another GM USB module configuration. Although the visible USB openings can look similar, its electrical connections and intended application may differ.
The three-rear-connector version shown in our comparison should not be replaced with a single-connector module without checking the factory configuration.
GM parts catalogs also list 13558185 as a service replacement for 13529873. That doesn't make 13529873 and 13525889 equivalent.
Remember: Same truck, same-looking USB ports, different electrical requirements. Always inspect what came out of your vehicle.

Why Does My Phone Charge but Apple CarPlay Doesn't Work?
This is one of the most frustrating surprises after a USB port replacement.
Your phone lights up, the charging icon appears, and everything seems fine. Then you try opening Apple CarPlay or Android Auto. Nothing happens.
Here's the catch: Power delivery and USB data communication are different functions.
GM 13525889 is identified as a charging-only receptacle. It should not be purchased as an upgrade for a USB port that needs to carry infotainment data.
Before replacing a module because CarPlay stopped working, try another compatible data cable, inspect the port for damage, check your infotainment settings, and test the original system.
If your truck needs a data-capable USB connection, verify the correct part number rather than assuming any matching-looking USB module will work.
How to Check Your Silverado USB Port Before Ordering
- Check the original part number. Look for the number printed or molded on the module. Confirm any superseded number through a reliable parts catalog.
- Count the rear connectors. Does your original unit have one connection or three? Compare their shapes and locations.
- Confirm the USB function. Is it used for charging only, or does it connect to Apple CarPlay and Android Auto?
- Check vehicle details. Record your model, year, trim, installation location, and VIN.
- Compare before installation. Never force a connector that doesn't match. If you're unsure, ask a qualified technician.
