What Does the APDTY 120303 Door Latch and Lock Actuator Do?
The APDTY 120303 is a fully integrated assembly that performs two critical functions in your vehicle's door system:
- Door Latch Mechanism: Physically secures the door closed when you shut it, engaging with the striker on the door frame to keep the door safely latched during driving.
- Power Lock Actuator Motor: Electrically locks and unlocks the door latch when you use the key fob, door switch, or interior lock button, moving internal linkages to engage or disengage the lock mechanism.
Because both components are integrated into a single unit, failure of either the latch or the actuator motor requires replacement of the entire assembly. This design is common on 2007 GM full-size SUVs and trucks, where the actuator motor and latch share a common housing and cannot be serviced separately.
What Are the Symptoms of a Failing Door Latch or Lock Actuator?
When the door latch or lock actuator begins to fail, you may experience one or more of the following symptoms on the front passenger-side door:
- Door won't lock or unlock electrically: The power locks don't respond to the key fob, door switch, or central locking system, though other doors may work normally.
- Repeated clicking or buzzing noise: The actuator motor attempts to move but cannot complete the lock/unlock cycle, producing a rapid clicking sound from inside the door panel.
- Door won't latch or stay closed: The latch mechanism fails to engage the striker, causing the door to pop open or require slamming multiple times to close.
- Interior or exterior handle doesn't release latch: Pulling the handle has no effect, or the door can only be opened from one side (inside or outside but not both).
- Door ajar warning light stays on: The instrument cluster shows the door is open even when it's closed, due to latch sensor failure.
- Child safety lock won't engage or disengage: The child lock feature becomes stuck in one position or fails to work at all.
In many cases, these symptoms are caused by wear in the actuator motor gears, corrosion in the latch mechanism, or binding in the door latch cables. Because the actuator and latch are integrated in this assembly, replacing the entire unit is the most reliable repair.

Important Manufacturing Location Requirement: This part is compatible only with vehicles manufactured in the United States or Canada. Vehicles built in Mexico may use a different door latch design and will not be compatible with this assembly. To verify your vehicle's country of manufacture, check the door placard (certification label) located on the driver-side door jamb—it will clearly state the country where the vehicle was assembled.
If your vehicle year, make, model, or manufacturing location is not listed above, this part may not fit. Always verify fitment using the live compatibility chart on the product page or contact APDTY customer service before ordering.

How Do You Install the APDTY 120303 Door Latch and Lock Actuator?
Replacing a door latch and lock actuator assembly is a moderate-level repair that requires removing the interior door panel and working with door latch linkages and electrical connectors. The general installation process includes:
- Disconnect the battery negative terminal: Always disconnect the battery before working on electrical components to prevent shorts or accidental airbag deployment (if working near side-impact airbag sensors).
- Remove the door panel: Remove screws, clips, and fasteners securing the interior door panel, disconnect any electrical connectors for window switches or courtesy lights, and carefully pry the panel away from the door frame.
- Peel back the moisture barrier: Remove or fold back the plastic vapor barrier to access the door latch assembly and linkage rods inside the door cavity.
- Disconnect electrical connector: Unplug the wiring harness connector from the old door latch/actuator assembly.
- Disconnect door latch cables and linkage rods: Carefully detach the door handle cables (interior and exterior) and any lock linkage rods from the latch assembly. Important: Inspect all cables for wear, fraying, or binding—worn cables are a common cause of door latch and actuator problems. Replace any damaged cables at this time.
- Remove mounting bolts: Unbolt the door latch assembly from the door frame (typically 3 bolts accessible from inside the door cavity).
- Install the new APDTY 120303 assembly: Position the new latch/actuator in the door frame, secure with mounting bolts, reconnect all cables and linkage rods, and plug in the electrical connector.
- Test operation before reassembly: Temporarily reconnect the battery and test door lock/unlock function, interior and exterior handle operation, and door latching before reinstalling the door panel.
- Reinstall door panel and vapor barrier: Once operation is confirmed, reinstall the moisture barrier, door panel, screws, and clips.
Safety Note: If your vehicle is equipped with side-impact airbags in the door or seat, take care not to damage or disconnect airbag wiring during disassembly. Consult a factory service manual for airbag-specific precautions if applicable.
For detailed torque specifications, wiring diagrams, and model-specific procedures, always refer to a factory service manual or professional repair database for your specific 2007 GM vehicle.
Frequently asked questions
Will the APDTY 120303 fit my 2007 Escalade if it was built in Mexico?
No. The APDTY 120303 is compatible only with 2007 Cadillac Escalade, Escalade ESV, Chevrolet Suburban, Tahoe, GMC Yukon, and Yukon XL models manufactured in the USA or Canada. Check the door placard on the driver-side door jamb to verify your vehicle's country of manufacture before ordering.
Can I replace just the actuator motor, or do I need the entire latch assembly?
The APDTY 120303 is an integrated assembly—the actuator motor and door latch mechanism are combined in one unit and cannot be separated. If either component fails, you must replace the entire assembly.
Why should I inspect the door latch cables when replacing the actuator?
Worn, frayed, or binding door latch cables are a common cause of actuator and latch problems. If the cables are damaged, the new actuator may fail prematurely or not function correctly. Always inspect and replace worn cables during installation to ensure reliable operation.
