I have a Lincoln 2014 MKZ. Woke up one morning and the car was completely dead . I jumpstarted the car and noticed I could not open the trunk. I can’t open the trunk from the panel in the car or the FOB or the button on the outside. I have to crawl through the back of the truck and use the kidnap latch to open it. I didn’t do anything and let the car sit overnight again and the battery was dead again. I went to AutoZone and they tested the battery and the alternator and they both passed. They also replaced the trunk relay fuse number 80. They disconnected the trunk motor because they claim it looked to be jammed they also disconnected the light in the trunk. I let the car sit overnight again and it was still dead the next morning. Dealership says they don’t know what the issue could be I have to leave it with them for a few days. Any ideas as to what the problem could be I found a new trunk motor online that I was going to replace but dealership says this is not draining my battery because it was disconnected.To my knowledge everything else works in the car. I am getting a drive control malfunction service required but I have had that for months and the car does not drive any different. Any ideas?
