I have a used Wii that was missing both side doors. I tried ones from a different unit before buying a replacement set. Both doors have one side that click in place and hold normal. One door will click in place but the pin sometimes pops out when opened. The other door will not click in place at all. Has anyone else had this problem and how did they fix it? I did not see any damage where the doors pins should click in place but who knows what the previous owner did.
