## Discrepancy

AT BEGINNING OF FLIGHT FO SAW LIGHT COMING THROUGH CRACK OF DV WINDOW, WENT TO OPEN AND CLOSE IT AND HAD HARD TIME CLOSING IT BUT GOT IT CLOSED. ON CLIMB OUT AFTER T/O LOUD HISSING NOISE COMING FROM FO DV WINDOW THEN TWO POP SOUNDS AND THE HISSING WENT AWAY. PRESSURIZATION LOOKED NORMAL BUT ON OCCASION FO COULD HEAR CRACKING COMING FROM WINDOW. PRESSURIZED AC IAW ERJ AMM 21-31-00. COULD NOT DUPLICATE HISSING NOISE .PERFORMED GVI OF WINDOW SEAL AND PERFORMED FUNCTIONALITY CHECK OF FO DV WINDOW IAW ERJ AMM 56-12-00. OPS CHECK GOOD  .
