Back in December 2021, roughly 6 weeks ago from when this video release, I repaired the tail light gaskets of a 2007 Mazda3. I recently checked in on the vehicle to see if the gaskets are holding up, which thankfully they are. However, I noticed two new leaks. One coming from the main trunk lid seal, and the other coming from the wiring harness that connects the wires inside of the trunk to the inside of the trunk lid (the wires/harness is for the third brake lid integrated into the trunk lid). Installing the main trunk lid seal is covered in another video. This video showcases repairing the water coming in from a poor seal around the trunk lid wiring harness connector with some silicone designed for automotive purposes.
Since a brand new grommet cannot be purchased from a local Mazda dealership, only the entire harness which is a few hundred dollars, I opted to try a simple silicone solution instead. This repair is an effort to minimize costs. Should anyone want to try this, please note to use silicone that can adhere to metal.

I have been struggling with multiple leaks in the boot on my mazda 6 and this is the last one I managed to pin point thanks to your video. Thank u so much 👍

Hi there. Thanks so much for this. My Axela has a leaky boot/trunk too. I'm still investigating where the leak comes from but I think sealing up where you did is definitely the place to start in case it fixes the whole thing. It's such a great car other than the leak.

Hello Mike, I am so grateful that I found your video as it might help figure out the issues I am currently having with my 2005 Mazda 3. Lately my reverse lights, 3rd brake light, brake lights, horn trunk light are not working. The reverse lights and horn work for a very short time after I replace the fuse blown fuses and the fuse blows with hours or a day. The 3rd brake light is not working at all. The brake lights and trunk light have some short. They come on and off if I wiggle the wiring harness with rubber boot (same one on your video). What dawned at me after seeing your video is that a month ago while checking my spare tire I noticed the trunk lining was wet and to my surprise a good amount of water in the well where the spare tire sits in. I drained the water but never thought or connected the issues with the lights that I am having. I am sure the water leak is due to that same rubber boot in your video. It could very well be that I have short in that white connector you show on your video or somewhere in that area. Cheers!!

You are welcome! Glad the video helped. You might want to also change the main seal that wraps around the trunk, which I covered a my most recently uploaded video.

Going to install a back up camera. What color is the positive wire?

I have similar issue with my 95 Honda odyssey ex. Rear liftgate. Haven't been able to locate the source

That's unfortunate and sounds frustrating. Sorry to hear. If willing and haven't done so yet, strip the entire cargo area of all the cloth and plastic pieces to expose the vehicle's metal/interior shell. Place a garden water hose on the roof of the car and let the water flow and run down everywhere. While that's going on, sit in the car with a flashlight (if needed) and see where the water is coming in, then work backwards to find the entry point. Try that, it might help narrow down the location of the source. Then seal it up with an automotive silicone that adheres to metal and/or plastics, or replace any broken, ripped, torn, or worn out rubber grommet or gasket with a brand new OEM Honda part, if available. I know the 97-01 Honda Prelude has trunk leaks where water comes in from the sunroof, but the small dark coloured rubber tube that connects to the translucent main tube - where the water from the sunroof flows through and out of the wheel wells - gets clogged with dirt and grime built up over time. Perhaps the Odyssey has a similar set up? The fix with the Prelude was to do the leak test (the process with the water hose mentioned above) then clean out anything that is clogged and replace any rubber gasket-like part and/or use some automotive silicone if needed. Overtime rubber just deteriorates and no longer does the job that it was designed for, and has to be replaced or repaired somehow. Overall, it can be a time consuming process, but it's worth it once completely fixed rather than having mold and mildew growing in the car from the water leaks.
