I have looked for some answers on Honda tech but haven't seen any specific answers re water behind the drivers side seat. If anyone has had the same issues, any help would be great. Or a link to the proper page. Thanks

 

try diagnosing the issue .
have a buddy spray your car with a garden hose while you are inside looking for the leak

 

You have to test - It it likely leaking somewhere else and running down the interior panels and then collecting behind the drivers seat.

Some threads say to check the taillight gasket, but could water run forwards to the rear floor area?

 

id say check the window seals and door seals

 

Thx, I'll start at the seals first.

 

I see a large rust hole in the fender well, right in front on the rear tire ( where you would jack up the car) maybe ill start there lol

 

Good luck man. I get it front and rear. I'll fix it when I repaint though

 

That's what she said lol. Sorry, I had to say that. I'm gonna glass it up one of these days. Hopefully that will solve it

 

Replace the metal, never glass it.

 

I don't have the skills or tools to weld. And the car is getting close to 500,000 km's.

 

Check the drain tubes they're probably clogged. That's been my solution several times.
