Lock actuator for fuel tank flap

[rogerkiu]

Hi all! Recently the lock of fuel tank flap works not well, sometimes it does not lock the flap when I lock the vehicle, sometimes it does not open when I try to fill up the tank. I guess the lock actuator is about to go, I need to replace the lock actuator. Does anyone have the experience of how to replace the lock actuator? Really appreciated if anyone of you expert could provide me a guide of how to replace the lock, step by step is much appreciated! Thanks in advance!
