recently the tailgate has been playing up on my 2005 mazda 6,when i unlock the car with the remote,the tailgate isn't unlocking but this seems to be intermittant as sometimes it is unlocked then the other night i locked the car and when i checked tailgate was locked it opened and triggered the alarm,could it be a faulty solenoid or a wiring fault?
