I am currently dealing with this same annoyance. I have noticed that it can take days and days for the carpet mat to dry out, especially because there is a thick section of some cotton type material attached underneath the carpet.
any update on your situation?
Just bought a ‘15 Wrangler and the previous owner placed a lock box under each seat. However, the keys for them are nowhere to be found. Can I get a replacement key or am i SOL and just need to take them out?
