Sure, you can see the location below, where I’m using a cloth and capillary action to remove the last of the water.
There are plugs at both the forward and rear end of the sill.
My passenger side is your drivers side, being RHD. Port side.
Although the corresponding sill is the same (I found no sign of moisture in that one).

Any ideas on how the water is getting into the sill? Through the rubber grommets?
