Rear drivers side footwell flooded

Hey folks,

I’ve got a bit of a problem with water in the footwell behind the drivers seat. Car has the pan roof. It’s only on that side. 1st thoughts were roof drainage or air con drain.
Gets a fair bit of condensation on these colder mornings.

Any ideas, or am I on the right track?

I’m currently having a fight with the seat bolts! Given them a good soaking with WD40 and will hopefully be able to remove them tomorrow. That will allow me to see under the carpet and see what lurks beneath.

Anyone had anything similar or any experience of this?

Thanks in advance
 
Thanks for that, I'll give this an attempt today.

Got the car in the summer, an Albi Blue 200. It's my first RS, so wasn't really sure what to expect.
So far I've had to put in a new battery, 4 wheels all powder coated, new wipers, 2 front springs, new drivers side hub assembly, rear brake caliper and pads, 2 handbrake cable's and a reverse light switch.
Great fun car through, and once I get this issue fixed it'll be nearing perfection. Currently got 4 Chinese ditch finders for tyre's so once they're done I'll be looking to put on Michelin PS4's.

I did have a look at the membership options, look's like decent value
