Description
Right Tailgate Lock for Peugeot 307 CC. With functional microswitch 8484L4.
This right-side tailgate (boot) lock is a direct-fit replacement designed for Peugeot 307 CC models. It includes a functioning microswitch (8484L4) that provides the latch position signal to the vehicle’s wiring harness. The part is suitable for automechanics and experienced DIY enthusiasts who need a reliable latch assembly to restore secure closing, central locking feedback and boot-open sensing on convertible 307 models.
Key Benefits
– Direct replacement for the original right tailgate lock on Peugeot 307 CC, matching OE mounting points and connector.
– Integrated microswitch for boot-open/closed detection.
– Restores proper locking and improves security and convenience of central locking operations.

Compatibility
Fits Right-Side Tailgate For Peugeot 307 CC. Verify part numbers listed above against the vehicle’s original part to ensure fitment. This latch replaces the factory unit and is intended for the right-hand (passenger) side boot/tailgate.
How It Works And Typical Failure Modes
The lock assembly secures the tailgate and contains a microswitch that signals the open/closed state to the vehicle’s electronics. Common reasons for failure include mechanical wear of the latch mechanism, corrosion and water ingress (especially on convertibles), broken or fatigued plastic components, seized internals from dirt or rust, and electrical faults in the microswitch or connector caused by corrosion or wiring abrasion. Failures typically appear as inability to latch/hold the tailgate, intermittent boot-open warnings, or loss of central locking function for the tailgate.
Replacement Procedure (Overview)
1) Open the tailgate and remove the interior trim panel to access the latch assembly.
2) Disconnect the electrical connector to the microswitch and any actuator wiring.
3) Unscrew the mounting bolts securing the latch to the tailgate and carefully remove the old unit.
4) Position the new latch, loosely fit bolts, connect the electrical connector and check mechanical alignment with the striker.
5) Adjust alignment so the tailgate closes smoothly and securely, then tighten fasteners to manufacturer specification.
6) Reinstall interior trim and test locking, central locking cycle and microswitch signal (boot open/closed) several times.
Installation Recommendations
– Disconnect the negative battery terminal before beginning work to avoid short circuits and unintended actuation of electrical systems.
– Keep fasteners and connectors clean; replace any corroded bolts or clips.
– Lightly lubricate the latch pivot points with a suitable long‑lasting grease; avoid contaminating the microswitch electrical contacts.
– Ensure correct alignment with the striker plate to prevent premature wear or incomplete latching. Test the tailgate through several open/close cycles and confirm central locking operation and dashboard boot indicator behavior before finishing the job.
Why This Part Fails Most Often
The most frequent causes are long-term mechanical wear and exposure to moisture leading to corrosion or seized components, damage to plastic parts from repeated stress, and failure of the small microswitch due to electrical contact wear or connector corrosion. Convertibles are especially vulnerable because of increased exposure to water and road spray.
Practical Tips
- When replacing the latch, inspect the striker and hinge alignment—misalignment can rapidly wear a new lock.
- Replace any brittle plastic clips or water seals found during disassembly to reduce future ingress.
- If electrical faults persist after replacement, check wiring continuity and connector corrosion before assuming the new latch is defective.
