Blown fuse tailgate

Hi, had a warning message tailgate open … definitely wasn’t! Fob didn’t work so got a new fob … didn’t work .. changed fuse .. did work…. Until I drove car .. then didn’t work .. work same message coming up and a blooming great big office chair in back of car that I now can’t get out plus don’t have use of rear seats I’ve ordered a new boot release which will be hear Saturday or Monday but wondered if anyone else has any suggestions …. I am so fed up of not being able to lock my car , get into boot … now use back seat ..lol!! I’ve had this car 15 years and have always loved it but getting fed up of its ‘quirks’ now . Would really value any advice

Can you hear the actuator working moving up and down but not releasing. Sometimes the lever can pop out from actuator from a worn bush. The door release handle can stick as the spring gets tired.
