Puddle of water on passenger side floor
Looking for some suggestions as to what could be the cause.
After a very rainy day and high winds, I noticed a pretty big puddle of water on the driver side floor. It was that deep that the water started sloshing about when the car was moving.
I checked everything else and it was bone dry. There was no water on the inside of the driver side window or windscreen. The glovebox and panel behind it was also dry so I've no idea where it could be coming from.
I've checked online and it seems to be a common problem caused by a bulkhead, hole in the wheel guard or a leak in the radiator system.
It's been raining again today although nowhere near as bad and there doesn't seem to be any fresh water.
Should I take this straight to the garage?
