    Hey Guys!

    I just bought a 2004 Toyota Tundra and it's my first truck ever and couldn't be happier to be a Totoya Truck owner cause I LOVE IT!

    I bought the truck from a private dealer and he didn't point out a couple things..

    I live in FL and it's hurricane and rainy season, it rains almost everyday. Couple days ago I noticed some water leaks.

    First leak - Up under the dash on the front passenger is leaking in multiple spots and looks like it's coming from the blower? Does anyone have a fix for this? Seems to be dripping from the screws on the blower...

    Second Leak - Behind the back passenger in the access cab against the frame water is leaking in the corner, can't find the source of it all..please see pics for details.

    Third Leak - This is close to the second leak, along the door frame in front of the second leak..not sure if it's just an access of so much from second leak or this leak is coming from a seal from the passenger door not being sealed properly?

    I have taken pics of everything..if anyone can help in anyway please let me know! I'm sure someone out there is having the same issue as I am?

    Thank you all!


    First Leak:

    Check to ensure that the rubber grommets are not missing in the floorboard under the carpet. Also check seals around windshield and windows, might have dried out seals around the glass. Do you have any roof clearance lights by chance?

    I had the same leak as your first one. I think this is the thread I used to fix it, pretty straight forward: For leak 2 and 3, I would start pulling side panels and investigate more. Could be from the rain “gutters” on the roof. The weather stripping could have deteriorated and now allowing water into the cab.

    I had the same issue with my 03. Drove me nuts and could never pinpoint where it was coming through the rear window. Used to soak up into the seatbelt. :mad:

    For leak #2 maybe check the seal around the third brake light above the back window. If water is getting in it could be running down the top of the window and straight down to the floor.

    This. Unscrew the brake light and visually inspect. Clean it up and reinstall. Use some caulk on the backside of gasket. Or, tape off and caulk the top and two sides but leave the bottom of light housing uncaulked for drain purposes.

    Not sure if its related but check your sides (forgot the name) above the mud flap behind front tires. Open doors and look for the little plastic flap below door hinge. Leaves and debris get trapped in there. You need a long stiff wire with a hook and some patience.

    Also, open your engine hood and see if debris is clogging the drain ports near the windshield corners. This drains down into the mud flap area mentioned above.

    Run your water hose to flush everything. The water hose can be used to test for leaks as well.

    Could be the cowl? (Thingy at base of windshield) leaking as well? Maybe a/c drain clog?

    So I took the four screws out and took off the front plastic face of the third brake light off, the whole thing won't come out cause it's sealed to the truck but there's space on the top where water can get in?? Is it supposed to be super tight against the truck or little space for water to go around? I put the face back on with screws and tightened it down really good, see if that helps?

    I took it off and cleaned it but the seal around the plastic face is flappy and falling off. I put back on and put four screws back on see if that helps? May need to seal up or order new third brake light.

    My 2004 leaked in the same place as your leak #1, and removing the cowl under the wipers revealed some rubber grommets which held the cowl screws in place had dry rotted. The first posters linked repair directions are a great place to start for leak #1 I ordered new grommets and no more leak. My 04 does not leak in the back though. The 3rd light would be my first guess though.

    My son's truck 2012 Colorado leaked around the gasket for the third brake light above the back glass. Silicone took care of it.

    The first leak that's on the passenger floorboard is coming from the cowl screws under the cover, remove the wiper arms, remove the cover, you'll see the screws under there. They have little plastic washer things that dry rot and leak directly onto the blower motor. Use some silicone sealant on the threads and around the head to cure that nuisance. The drivers side rear leak is likely from the weatherstrip running the length of the roof, again use black silicone sealant if you can find the exact spot.

    Any thoughts on removing the clips without breaking them? I'm 0 for 1 at the moment...
