Water under driver side floormat

So last night I went out to my truck because I forgot my wallet. Look down and thought man my floomat is dirty so I took it out to shake it off and it was wet on the underside. Looked at the floorboard and sure enough my floor is soaked. Really weird. Any ideas? A/C? It has rained in the last few days but shouldn't be inside my truck.

 

Heater core lines run along that side. Hopefully one isn't leaking or even worse, the heater core itself. Can you tell if it's antifreeze?

 

Definatley water. I am wondering if running the A/C for so long may have frozen the vents and then thawed. Maybe?

 

Not if the AC is working properly, the system should never freeze up. Has it been raining? There is a TSB for a body seam on the drivers and passenger side not being fully sealed from the factory. I do not know if it applies to your truck ( year etc ). I'll see if I can locate it.

I have a 2012 Taco and had a similar problem, but only on passenger side. It turned out to be a clogged A/C drain hose.

Well it hasnt done it in a couple of days now. However when I commute to work will be the test. It is about an hour drive and I run my AC on full during the commute because it has been so hot here lately. FYI it is a 2013 so I guess that TSB does not apply.

 

Look for the round rubber plug that is near the seat... if that isnt in there you would have a 2" open hole to the underside of your truck that could have maybe let rain water in. Thats the plug that i cut a slit into to run wiring to the back of my truck.....
