I had the same problem in my changer, when I opened the top cover, there was a hidden reset button, I pressed it, it is okay. I think it may be from dust or cold, but if you haven't tried it, reset it .. also how did you remove it :)

I have not tried, I will wear it tomorrow To remove it, I removed the black plastic piece of the trunk lock from there, then pulled the locked screws on the trunk lining with a flat screwdriver and wasted off the lining. There are already 2 hex head screws holding the case and you unscrew the socket after you open them.
