2015 Model S door actuator stopped working a month ago. I replaced it with another one today. At first few tests other new one did not release either! I sent a service request on the Tesla App explaining the problem and situation. The door handle module was upgraded in 2021. Things were working up until a few months ago.
I went to the main screen and put the car into service mode. Then exited service mode. I tried the door and it opened. It worked many times. I was curious about the old existing actuator so I reinstalled the old one and it worked! Next I installed the new one again and it worked again and again. Woohoo, success! As well I had not yet received a response from Tesla service. I then cancelled my service request. Within an hour I went for a 25 km drive and went to open the rear left door again and it has not worked since!! I will keep an open mind and try again to find a solution. I have reset the main screen many times. If any body with relevant information can chime in it will be much appreciated.
