Unable to close driver's side door - will not latch. Found small piece of black plastic in the door latch itself. The latch will not move; therefore, won't catch on the pins. Ready to order from Mike the lock actuator, but trying to determine if that is the piece I need. If so, how easy will it be to replace? I am NOOOOO mechanic, a newbie, and experiencing problems with my SSR preventing us from having the fun we want to have. Getting frustrated and need help from my new "SSR Family". Thanks.
