If wing on trunk lid check for rust on holes.

 

Cheers for all ideas here. My trunk has loads os water to. The wheel kit has an inch in the plastic part.
Before i pay Mazda for new seals, thats about $90 in the UK where im from id like to check the sunroof drains but i have know idea where they are.

Please advise. Happy New Year!

 

I checked the sunroof drains by pouring water into the channels on the sides of the sunroof (with the sunroof open) and seeing the water come out just behind the front wheel wells.

 

i have a weird water problem as well. had one tail light building up condensation..then fixed it...now having the left one start, and now all of a sudden i see my carpet on my trunk steaming cause of that water.....gaaay

ill give it a look tomorrow

 

noticed carpet was wet the other day opened up the jack kit portion and found about 1-2 inches of water in there i will try the sunroof method to see if that's the cause. how would i go about checking my tail light seals??

 

Water in the trunk is caused by the taillight gaskets.

This should fix it.

This is a customer's car that got dropped off to me on a semi truck a couple weeks ago. One of his taillights is literally half full of water, so I guess it's from that.

 

I just had my RX8 rebuilt after it was hit on the right rear panel. I had a swimming pool in the trunk after a rain storm.
Take the plastic parts out, peel back the liner and see if there are any holes that don't match the hole coverings on one side. Cover holes with electrical tap or find rubber discs at a hardware store that fill the holes. To ensure water proofing use a clear silicone caulk around the rubber discs before inserting them into the holes. Allow to dry and replace all interior parts.

Also, look at interior of wheel wells and see if there are any missing screws. Call dealership and email them a picture of the car parts that are missing screws. They may have it or not. If not remove the complimentary screw from the opposite side and take it to a hardware store (Home Depot or Lowes are good) and ask someone to help you pick out the right size screws. Use Loctite to secure screws into holes.

The rubber seal on your trunk can also leak. The replacement is around $80-$90. Remove old one and put new one with the join seam at the top of the trunk and push into place. It's that simple. Don't have to pay to fix it.

If it's your window seal, take it to a car window replacement store and have them do it. You don't want to damage your fog or antennae wires.

 

Some times the tail light well where the trunk hindges are gets clogged uo and leaks into the trunk area because if it gets clogged it hold a pool of water that spills into the trunk area. It happened to me.

 

Hi Guys,
So recently i discovered water leaking into my trunk. i removed all clothing fron the trunk to locate the leaking source. The rearlight seals are new and no water or Condesation in or around the lights. I have put some dry papers all around the trunk including the trunk lid (i dont have a spoiler installed and the trunk seal is good). The source of water is from the left side of the trunk just bellow the fuel filler lid/cap. Any body had this problem before? or does anybody know how water is gettinig in there?

Thank you.


UPDATE:

After Testing the possibilities of where the water is comming in, i was able to find out that the water was comming in through the sealing material of the rear windshield. Exactly where the roof rail touches the seal (Drivers side). The seal has been degrading over time. The water was going in and making its way to the trunk and the back seat where i found the serivice hole cover of the fuel tank also rusting. The rear windshield was removed at a Auto-Glass shop, the old seal was complete removed and the area was cleaned before installing the windshield again with new sealing/gluing material. The water stopped leaking eversince.
Note: the windshield can break while removing, it must be taken out by professionals while being VERY cautious.

Had an issue with the plastic pieces beneath the trunk lid as well, hopefully its an easy fix
