Hello I'm new to this forum thing but I really need help. I just baught a 94 integra gsr and I have rain in my passenger floorboard. I have already looked everywhere for the leak and ended up pulling up the carpet and noticed a small hole behind the ecu on the firewall. Not sure if this tiny whole is suppose to be there or not but it leaks water every time it rains. A friend told me it could be the door seals and a YouTube video pointed me towards the weather strip at the bottom of the windshield, anyways I checked the feet blowers no signs of water drips and its not wet anywhere along the sidewalls of the carpet and I can't find a way to track the water through this hole and back to the top. If you have had this problem it would be greatly appritiated if you could fill me in so I can get this fixed asap. Thank you

 

A picture of the hole would help.
