PSA for newer PIU owners. Check for water leaks in body.

[2013PIU]

I've owned my 2013 PIU for a few months now and after going through a few car washes with no water leaking inside I thought I was okay. Here in Northern California we just had our first big rain storm and I was greeted with about 2 inches of water on the passenger side floor boards front and rear this morning. Luckily I have the vinyl flooring and it was pretty easy to get under it to vacuum and dry with a towel, but I still cannot find where the water was coming from. Tomorrow I'll be pulling the door panels to check for seal leaks and will silicone all the roof holes that currently have bolts plugging them.

When water pools in the regular Explorer it is usually due to the drain tubes being plugged but I believe it is only on those with the moonroof. Not sure if the PIU has them.

Thanks, Peter. No moonroof on the PIU unfortunately, but I think it may be the weatherstripping/door design. I do recall quite a bit of water dripping out of the rear door when I opened it. I think this guy demonstrates it pretty well:

If it's just passenger side, could be from fresh air/hvac/firewall area.

Have you checked to ensure the drain holes are not blocked causing water to backup in the door? If they are clear then perhaps check out the possibility of KayGee's post.
