You don’t know how much this has helped me. I have a 2013 and I don’t drive it often due to driving company car so I was surprised to see 7 to 8 inches of water in my trunk under tire and soggy driver back side floor and unfortunately mold and condensation. I was horrified since it sits and all windows was up we cleaned entire car twice only to still not understand were all the water was coming from so thank you Sir thank you
@@jakobalday7978 my Malibu has continued to be dry. Those valves were definitely the issue for me. The only two other things that I found that could cause it as well. According to other people. Is either a clogged sunroof. Or the tail light gasket.
@@NoU303 you're welcome my friend. I'm glad I was able to help. On a side note I might even fixed the water that was going on the driver side floorboards as well. I don't know for sure but not only is there not water in the trunk but there's no water on those floorboards either. But I got to do more testing to be sure.
Black engine permatex. But any real automotive silicone should work. It shouldn't get any real heat back there. But I believe the black gives it a stronger hold and it's more heat resistant.
My brother owns a 2017 Malibu Turbo. He lives in San Diego and when it rains he gets water in his trunk, a lot of water. The dealer was unable to find the problem after checking the tail light gaskets. He took one more look at the problem and discovered that the trunk vents open at the slightest of air movement. So he taped over the opening for the bottom 3 vents leaving the top vent opening uncovered. All 4 vents still open and close together but now water doesn't have the ability to leak into the trunk when there is water on the road from rain. Instead of the water leaking into the trunk it runs back out the bottom of the vent. The air pressure in the cabin is still released from the heater/air condition when it not in recirculation. When closing the doors or trunk the air pressure is still released. He also experienced less road noise. This solved the issue of water getting into his trunk. I hope this helps others with the same issue. I was unable to find anyone resolving this problem. Please post your result using this fix.
It's the vent in the trunk. Once you pull it out you can see where the seal is. For whatever reason it doesn't seal anymore. So put the silicone on that seal. Slide it back in through the hole and pull it into the trunk locking it in place
