Default Leaky window at a-pillar/roof juncture

I have a 2003 model. In a carwash there is a significant leak - fast drip - that enters at the window near a-pillar and roof juncture. Drips become a small stream that flows from the bulbous portion of the weatherstripping.
Anyone have a similar problem and/or solution?
Rider's door stripping looks the same as driver's side. Neither stripping appears damaged, but only driver's side drips.

Read that Lexus tested window seals on these with a literal firehose. Must be something to fix it.

Testing New and perfect is one thing, taking a 20 plus worn is another. To each their own but hand washing is where mine will be going.

The seals are old. Aside from replacing the seals, I highly recommend using shin etsu (or similar) grease. It rejuvenated the dry weatherstripping on my 20+ years in California sun SC.

Check your trunk weatherstripping as well.
