Default My RX330 is drowning!

No not really... but sort of.

Leaks, along base of a-pillar, footwell structure (by parking brake). Not a little, but a lot depending on rain/snow melting.

Fills up the cubby where one of the ECU's sits and flows freely into the insulation under the mat, and then the mat.

Back story, minor issue last year on pass side. Blew it all apart. Got it down to floor. Dried everything out. Took out sunroof drain (with removal of A-Pillar cover), and checked connection; as it's two tubes tied together. Took off rocker cover, blew everything out, all the dirt, powerwashed any mud out of there. Problem solved. Drains unclogged.

Fast forward to now. This has been attempted to fix four times to no avail. The one video on youtube is ****. Doesn't help or guide with anything. I've taken a micro-camera monitor thingy to look in the whole area - NO BLOCKAGES! ARGH

Punched my rear door out of anger and time wasting with this stupid SUV... and dented it.

Back to solution. Started drilling holes where the wates was coming from, made it worse. Patched with seam sealer and solved problem, for three weeks, then winter started... now the floor is wet again! I'm at a loss.

*The lines are clean. The drains are clean, I've even drilled them bigger. I've cut the grommets in floor pan to drain water faster.

I'm done. The mech's can't even figure it out. It just doesn't make sense !?!

Leaking windshield? You got to fix it, or it will fry electronics and then add to more $$$$

Nope. Everything around the windshield is fine. A-Pillar's are bone dry. Nothing running down (outside of) sunroof drain tubes, all inside.

A dead giveaway with something as easy as that is a lot of condensation in the car... this thing has survived many harsh canadian winters where condensation would be super obvious.

Not going to argue... you surely looked at the firewall inside.... have no doubt. WS leaks in various places. Unless you have, like someone else here, crack in body leaking through...
