Lock and Unlock
 

My car starts having problem with lock and unlock problem. I think sometimes the signals light and rears light flash when I press Lock or Unlock, and sometimes they don't flash at all. Anyone know why?

one of your doors or sunroof prob isnt closed all the way. When i adjuseted my rear hatch stoppers I backed them out too far at first and lost my lights flashing, but when I tightened them up a bit the flashers came right back.
