Last night we had a deluge of rain. I came out to my truck to see the passenger side rubber mat had become a lake. Fortunately the mat contained the water and it was easy to take care of, but now I have a water leak to contend with. I suspect it's the cabin air inlet at the base of the windshield. May some drain has plugged up? Anyone else have this issue?

Yes, I had this issue once on my 04 Sequoia. Just once - but it never reoccurred luckily. I was also parked on a hill with some debris in the windshield, so I think the water dammed up and rolled down the back firewall into the cabin. Open the hood and try cleaning out all the leaves, grime, and debris at the base of the windshield and engine compartment so the rain water can drain properly. That seemed to fix it. I did not have to apply any RTV silicone, but if the problem keeps occurring, you may try applying some around the plastic wiring harness opening in the engine firewall into the cabin. That seemed to be the source of the water for me. But after I rolled the window down and left it in the sun to dry out and cleaned the debris, it was fine.

Fairly common problem actually. Not saying this is how to fix yours but its a cheap place to start.

Thank you very much! Looks like i'll be doing some reading and poking later. This had to happen on a Monday!

According to the local weather station, I had two inches of rain drop on me for that particular storm. Another less-severe storm came through last night and I checked the floor mat to see if anything came in. There was only a few drops of water on it.

Living at an apartment, this repair will be a little tricky. The management frowns upon car repairs in the parking lot. This isn't as invasive as some repairs, so maybe I'll be able to do it this weekend.
