What Does the Tailgate Lock Actuator Motor Do?
The tailgate lock actuator motor is a small electric motor built into your rear door latch assembly. When you press the key fob, dash button, or door-lock switch, the actuator physically moves the locking rod or lever inside the latch to lock or unlock the tailgate. In SUVs like the Ford Escape, Mazda Tribute, and Mercury Mariner, this actuator controls the liftgate; in Ram pickups, it secures the tailgate.
APDTY 153445 is the motor component only—you reuse your existing latch housing and mechanical parts. If the entire latch is damaged or corroded, APDTY offers the complete assembly under part number 120639.
What Are the Symptoms of a Failed Liftgate Actuator?
When the actuator motor fails, you'll notice one or more of these issues:
- Tailgate won't lock or unlock with key fob or power-lock button – you must lock or unlock manually with the key or interior handle.
- Clicking or buzzing noise from the latch when you press the lock button, but the lock does not engage.
- Intermittent operation – sometimes locks, sometimes doesn't, especially in cold weather.
- All other doors lock normally, but the rear tailgate does not respond.
- No mechanical damage to the latch itself; only the electric actuator motor has worn out or stripped gears.
These symptoms indicate the actuator motor has failed internally—typically due to stripped plastic gears, worn brushes, or water intrusion over time.

How to Install the Tailgate Lock Actuator Motor
Replacing the actuator motor requires removing the tailgate interior trim panel and the latch assembly. This is an intermediate DIY job; follow these general steps:
- Disconnect the battery negative terminal to prevent accidental lock cycling or short circuits.
- Remove the tailgate interior trim panel by prying out clips and removing fasteners. Disconnect any wiring harnesses for speakers, defrost, or lights.
- Unbolt the latch assembly from the tailgate edge (typically 2–3 Torx or hex bolts).
- Disconnect the actuator rod and wiring connector from the latch.
- Separate the old actuator motor from the latch housing (may require small screws or release tabs).
- Install the new APDTY 153445 actuator into the latch housing, reconnect the rod linkage, and secure with screws.
- Reinstall the latch assembly onto the tailgate, reconnect the wiring harness, and test operation before reinstalling the trim panel.
- Reconnect the battery and cycle the locks several times to confirm smooth operation.
If your latch housing is cracked, corroded, or the mechanical linkage is broken, order the complete latch assembly (APDTY-120639) instead of the actuator alone. Always refer to a factory service manual or professional repair guide for torque specs and detailed disassembly steps for your specific vehicle.
