Today was all about water drainage: A/C condenser drain and Sunroof drain.
AC drain extender- this was easy. I purchased the Cruiser Garage kit and this took about 2 mins. Worth it simply for the simplicity and not having the make multiple trips to the hardware store (see below)
Next, the sunroof drain-
The backstory here is that my GX is now a Pacific Northwest ride. The move from Southern California over the winter was rough on the GX which spent its entire life in the warmth. So now, being in constant wet, rain, and snow, I’ve discovered all the flaws including this sunroof drain.
I kept getting extremely fogged windows in the mornings. Recently, I took out the WeatherTech mats and found…wet carpet in the front passenger seat.
Some steps to fix:
1- Fished some weed whacker line down the drain from the top.
2- shot some compressed air down it.
3- tested by pouring water down. Success, the water drained.
But, the carpet got wet again. Not fixed.
I pulled apart the lower trim pieces to see where the water was getting to the carpet. I found the culprit:

The pvc drain tube disintegrated to about 3” above the drain hole (right behind a bunch of electronics). So it technically wasn’t clogged, it was just draining into this carpet/wiring zone. Not good!
Off to the hardware store.
Basically, I ended up cutting out the bad PVC and replacing with new, clear PVC.
Parts:
5 feet of 3/8 1D X 1/2" OD PVC tubing
One brass coupler (1/2” each side…this fit the OEM tubing better and was very tight on the 3/8” ID new tubing. Fine by me!)
One 1/2” hose clamp
Beer
I pulled the A-pillar trim off and started the surgery up here. I cut OEM tubing (which is slightly bigger than 1/2” ID tubing btw) and plucked out the bad portion. Then I fished the new PVC tube down into the drain hole, behind the wiring and computer stuff. This sucked- there is zero room here and I wasn’t going to remove 10 wiring harnesses- that looked harder anyway. I connect the new to the old with that brass coupler and put the hose clamp around the OEM tube side since it was slightly bigger than the coupler.

The hardest part was ensuring the new tube went into the correct hole and deep enough to stay and drain properly. Tested and observed carefully- NO WATER in the cabin now!

I still think it’s strange that Toyota/Lexus drains water directly into the frame; the AC drains right above the frame rail. The sunroof drains into this unreachable cavity of the frame (I guess). I would have preferred to extend the new pvc beyond so it can drain directly out like the new AC drain. But alas, I couldn’t find the way to do it before the beer and the enthusiasm ran out.
