Hello, I have a 1993 SR5. My avatar is the truck. I live in the pacific northwest where communist, socialist and rain are common. (No more politics, I promise).........whenever it rains very hard or for a long time my passenger floor get pretty wet. I'm pretty sure this isn't related to my AC since I don't get a chance to use it often up here. I'm looking for someone that has experienced this and fixed it. An old pillow case full of kitty litter does wonders but it's getting old having to fool with this. Thanks in advance..........

do you have a sun roof? If not, my guess would be the windshield.

Thanks for the reply. I do have a pop up sun roof that used to leak but I replaced the rubber and cleaned the drain holes. It stopped and I haven't opened it since. As far as the door and winshield there's no moisture around those areas. I'll dig deeper. Is there a way it could be running down the inside of the firewall? Keep in mind it's on the passenger side only. Thanks again.

I had the same problem on my 88, pulled the fender liner from the wheel well and it was packed with pine needles and dirt. That stuff caused the water to run into the cab footwell and not out the drain holes. Dug all the garbage out ,sprayed with a hose and it solved the problem.

This reads like a likely possibility. I have to dig into that to fix my retractable radio antenna anyway so hopefully I can kill to birds here. I had to do that with my sunroof also. Lots of pine needles where I live. They get everywhere. Might be a couple days but I'll report back with my findings. Thanks all.......

I would also lift off the cowl cover, the louvered part between the hood and windshield. If too many leaves or pine needles get in there, it can block the escape paths for water and it will fill up and overflow into the fresh air intake for the HVAC. I think you'll be surprised at the amount of crap under there.

Mine was leaking past the sunroof, down the headliner, down the A pillar trim and onto the floor. Very ninja like. Get out the garden hose and start checking.

Quite a lot of pine needles under louvered cover in front of the windshield. I cleaned them out. I would like to actually pull it off and do a better cleaning. If anyone has a resource for how to do that please share. Also and I know this is probably reaching but if anyone could point me to a diagram of all the "drain" holes I'd like to go thru all of them The truck being 27 years old I'm sure could use some drain hole cleaning. I did clean all the drain holes on the sunroof using mechanics wire. I replaced the rubber seal. That seemed to do the trick. That was over a year ago and hasn't leaked since. (I also haven't opened it since) The current water issue isn't related to the sunroof. Hopefully cleaning out the air louvers help.

Remove the wiper arms. Should be a couple/three screws where the hood and cowl cove meet. Remove screws and lift off cowl cover. Enjoy!

If it's anything like the cowl in my '87, the two at the very ends by the hood hinges are these maddening snap-in fasteners that usually don't survive being removed. I popped in a couple of threaded inserts with my nutsert tool, used some SS screws. But ya, that's the hardest part, it's easy to remove (once you get the wiper arms off).

After you pull the cowl, remove the fender liner and then run water into the cowl. There is a drain at the corner of the cowl, at least on my 88,that drains down the inner fender well and you should be able to trace the path of the water. I also had debris trapped in the space between my door( passenger side) and fender.

While I'm working on this let me share a pretty easy way to clean up the mess. Wet/Dry vac then take an old pillow case. Fill it with Kitty litter and spread it out over the damp carpet. Leave it at least overnight or longer. Works great. I've got a large bucket of DampRid sitting on the floorboard right now that seems to be working to remove the moisture in the cab. Not the water, just the dampness. I'm going to get into all the above ideas this weekend. Thanks for everyone's time and ideas. This truck has been really good to me. I hope I can fix this.

Good idea to clean out the little drain holes on the underside of the cab at some point. They are angled up away from direction of travel. When they are clogged, moisture collects above the pinch weld, and then rust occurs in the bottom of the cab. I think there are 6 on each side.

How large are these holes? And are they up thru the frame or the actual cab? Thanks......

They are about dime sized. They are little flares in the pinch weld along the bottom edge of the cab. Angled up and towards the front, so opposite of travel direction. If they clog, they will contribute to cab rusting out in the rocker area. Very good idea by Toyota, as long as they don't get clogged with dust, mud, needles, etc. I clean mine out with compressed air and then shop vac about annually now. I would post a picture, but it is monsoon season here, so I am avoiding lying on wet concrete underneath the truck.
