Hey everyone, I have a 2009 Dodge Challenger that has moisture building up in the spare tire compartment where the battery and rear fuse box are located. It usually happens on colder days in the winter (60 degrees) after it has rained or snowed. I live in Seattle so we get a lot of rain. I haven't noticed any water leaking into the trunk, however, I sometimes feel like the spare tire cover in the trunk gets a little damp. I have no idea how it gets damp. I tried running a hose over my trunk while I was inside of it with a flashlight but nothing leaks onto it. I'm starting to think that the moisture from the spare tire compartment rises and gets the spare tire cover damp? I attached a video below of the moisture that builds up INSIDE my rear power distribution center (trunk fuse box). Also, some of the moisture that builds up around my battery terminals. Last year this caused my HVAC controls to completely stop working. All three relays in the rear power distribution center were so rusted I had to replace them all to get it working again. If anyone has any advice on how to stop the moisture build up I'd greatly appreciate it!
