SOLVED! Rear Hatch Rattle..

SOLVED! Rear Hatch Rattle..
I did some searching to see if this had been posted before but it didn't get any hits so I figured I'd post what I did to fix my rear hatch rattle.
I commute about 7 miles on the I-280 Freeway between 880 and the 85. Anyone from this area knows it's somewhat bumpy.
More often than not there would be a rattle in the rear hatch area that was annoying as hell.
I tried re-seating all the trim pieces and the problem would go away for a few days and then return.
Last weekend I pulled down the entire lower (dark plastic) cover by removing the two screws and and giving it a good tug. Nothing in there looked loose but I heard some things rolling around between the sheet metal.
So I fired up my air compressor and hooked up my air gun and gave it a good blowing out. Several chunks of plastic debris and some sealant goo that had dried up flew out (wear safety goggles). Probably from the rear lip spoiler install.
I got everything out and put the cover back into place and took a ride. The rattle was lessened but still there.
So I took apart all the trim in the rear hatch looking for anything that might cause a rattle. Under the upper trim piece I found the culprit. There's a section of the wiring harness for the rear dome light
that can flex enough to tap on the sheet metal and cause a rattle. So I shoved a rag between the harness and the sheet metal and put the trim back into place and took a test drive. Rattle GONE!
Rather than have it jury rigged I took things apart and put a nice piece of foam between the harness and sheet metal with some hot glue as a permanent fix. 100 miles later and no more hatch rattles.
I also informed the Service Manager at the dealership that I had found a solution to the rattle since at the 5K service they could not figure it out.
I hope this helps others with the same problem.

That's awesome that you figured it out! Is there any chance at all that water could get to that area? If so, you'll want to make sure you don't use anything that will absorb water and stay wet against your sheet metal. Great job!

I don't have a constant rattle, but there is something loose in my hatch. Sometimes when I open or close the trunk I can hear something rolling around - I'm pretty sure it's not wiring because it sounds like it's literally moving around, not just rubbing on something. If it gets annoying I'll pull things apart but in my general experience these things never stay as tight as they were after you pull them apart once.

Great job, Thread. I have had this "metal" sound rattle for quite a while. I have tried putting tape on the metal part where the hatchback connect with the car. No luck. I tried someone's else suggestion about putting foam tape on the rubber stoppers on the side of the hatch. No luck.
This one sounds interesting. As suggested, can you post a PIC of exact location?
Thanks.

I'd like to see pics too.
My rattle is most definitely on the passenger side of the hatch though. If you're talking about the rear dome light (driver's side), you made have a different rattle than me.

Unfortunately I took pics when it was jury rigged and forgot to take pics
of the finished product and I'm hesitant to pull off the trim again in fear that I induce another rattle
I hope this helps.
And, since it's within the seal for the hatch there are no concerns of water getting in.

Also, when this was rattling I could swear that it was coming from the passenger side but there is no wiring harness on the passenger side.
When I did have a passenger side rattle it was the passenger side seatbelt rattling against the plastic on the passenger side uh thing you pull on to recline the seat forward and move forward so someone can get into the back. I just positioned the seat and the recline so that the belt buckle and release don't get in contact with one another.

I'm definitely going to take a peek at this harness suggestion. Only takes a minute or two to pull the plastic off. Couldn't hurt to try. Thanks!

is the noise the tapping sound only occur when over bump?
An earlier post mentioned to add some foam tape on bumper stopers. But those basically didn't help. Now this post are saying the wire harness is the guilty party. I'm gonna try it. Except, are you sure it's the one that makes the noise?
I mean, i thought the sound is like "tap tap tap" on the glass or something.

You can reproduce it by taking off the top trim piece and tapping the conduit between it's two fastners and you'll hear it. And if it makes that noise while I'm gently tapping it it sure as heck is going to make it as the car goes over bumps, etc.
But, again, this is what worked in my situation. I'm curious to see how many other people with rattles tries this out and the rattle goes away.

Thanks, I'm gonna try it. Just one last question, is it hard to pop open the plastic over for that area? Any special caution I should take?
