I discovered today accidently on my 2007 IS 250 that the rear floorboard on the passengers side carpet is a bit damp. Not soaked, but damp so I pulled up the mat to let it dry a bit. I came here immediately to see what it could be and saw the A/C mentioned, door seals and sunroof drains.

I cleaned the moldings although they look good and poured some water down the sunroof drains and they seem fine. I then let my A/C run for a good while here in Florida and after a bit there was a large puddle of water under my car from the evaporation. Could it still be a plugged drain?

It did rain hard yesterday here and I drove through it this morning also on the way to work. I do have the extended warranty that should cover it hopefully. Aggravating that here it goes with something else again!

Yes, more than likely it is the A/C drain blockage TSIB. The previous owner of my 350 had this problem around 25k miles. The dealership fixed it and replaced the entire carpet.

GL!

Speaking of driving in the rain, has anyone ever noticed that by the side of the door you'll hear rain drops -- sounds neat.

You'll need to listen next time; even when it's pouring rain outside, it sounds like raindrops on a pond.

um, the AC drainage tube is in front of the vehicle. OP is saying that its damp in the REAR of the vehicle. I would cancel out the blocked AC drain tube.

i had this happen to me with my old LS. but only because it was slammed and it flooded here in vegas. the entire rear flow was damp. other than that, that was my only experience

this TSB does not involve a tube so i am taking it in tomorrow morning to see what they think.

A blocked A/C drainage tube can and will cause mositure to accumlocate in the passenger side floorboards.

Is250gurl, have noticed any dampness on the FRONT passenger side floor board?

is250gurl

no dampness in the front as of now and that's what puzzled me at first.

I know it's simple, but are you sure the window back there was up all of the way? Even with my window visors, the VERY back of the window doesn't get covered by the visors if lowered even slightly.

By the way, grab yourself some Damp-Rid to help suck up the mositure back there or in the cabin in general.

yes it was up as the top of the floor mat was dry but underneath the carpet was damp and plastic on back of mat also showed water. the seats are dry also.

visors in the back seat? it's going in tomorrow so too late for damp rid. i haven't run the air in two days now, just the fan to help dry it.

Window visors...I guess you do not have them :

is250gurl

no i do not. my service advisor this morning said there is a pan underneath that area that water can accumulate in. we shall see what they find today.
