FA REPORTED INTERMITMENT CLICKING SOUND COMING FROM AFT END OF L2 DOOR DURING CLIMB OUT. THEY ESTIMATED IT REOCCURRED EVERY 30 SECONDS AND STOPPED WHEN WE LEVELED OFF AT FL 280. NOISES WERE NOTED ON THE DESCENT. NO PRESSURIZATION WAS NORMAL AND COMMUNICATION WAS NORMAL. GROUNDED - YES. ALL ITEMS ON MIG 2C 40-0083654, 40-0083655 INCLUDING NOTED DISCREPANCIES ABOVE CORRECTED. RE-PRESSURIZED AND NO DEFECTS NOTED.
