Rear window replacement is OVERDUE!

...the RMS could have used one though.

something much smaller that's also designed to absorb a particular bodily fluid.

Have you checked the drains to make sure their not clogged with leaves or other debris?

Are you talking about the drains the brains in the door ? No, I was talking about leaks from the rear convertible window. But how do you fix the leaks in the doors ?

There are four of them in the back, With the top (and clamshell) partly open, on each side there is a drain near the bottom of the plastic liner. There is another one right near the end of the channel close to the door frame (near the tip of the clamshell). If these get clogged, you'll get water into the interior during a heavy rain.

There are also two drains at the front. One on either side of the battery. Again, make sure you keep these clear of debris.

Go to a boat upholstery shop, have them install a new window and stop the leaks.

This is only a stop gap measure if you can't replace your window right away.

And in terms of drains, Guenter is referring to the exterior drains.

There are also drains in the doors as well that can flood water into the car, but part of the challenge with these drains is that they just aren't big enough - they are designed to drain the water that gathers in the door from the window seals onto the outer rocker panel/door sill but I have found that when the car is parked during one of the torrential downpours that we seem to get lately, that the water accumulation just overwhelms the flow rate for these drains.

I'm confused where you put them... I have had interior water issues with my car, much worse in the past.

Over the winter, I used 2 large tubs of DampRid to keep the moisture down. I don't notice puddles or collecting in any particular area. In the past, I used to get water under the driver's seat.
