We've had a LOT of rain her the past couple of weeks and it took a week of no rain for the smell to appear. No wet spots on the carpet or leaks were noted during the sometimes torrential downpours. But here's what I did find... While looking for the A/C evaporator drain tube, I came across a rubber grommet seal that a wire bundle passes through on the passenger side about a third of the way up the firewall. It's about 2" in diameter. You non-Americans will have to figure out the metric on that. (I'll try to post pics but that's another story) The grommet had come out for some reason. It's too far up, in my opinion, for road debris to have knocked it off so I'm stumped on how it came off. There was sound insulation immediately on the other side of the hole but I could not determine if it was wet. It should have been soaked considering the location and water being splashed up during rain. It was not easy to put back in place but I did manage to get it back into place.Also, the A/C drain line is extremely difficult to find, even with the service manual pictures. You can't really see it unless you get right underneath it as is does not stick down and the part of the hose where the water exits is flattened out. The hose also has a pretty good bend in it. It's too flexible to insert anything to clean it out. At least I have not figured out a way. Has anyone successfully cleaned out the A/C drain line?
Hopefully the smell will go away in a few days as I can't find the source of it inside the car.
