Just bought 02 went through car wash and found 3 to 5 inches of water in spare tire well looks that down by lower frame missing piece which allows water to drain out not sure any ideas thanks big e

you might look around at www.opposedforces.com for a drawing of what the seal looks like - I have no experience with sedans.

 

or, a collision center might be able to fix this for you.

Big e,

 

You don't say if you have a sunroof, because the rear drain tubes of the sunroof exit the car between the rear bumper cover and the rear quarter panel. If a tube has cracked or come off at the top, water could find its way into the trunk area and spare tire depression in the floor.

 

If that's not it, it could be the rear windshield needs resealing, or the tail lights the same thing. The absolute last thing to consider is the trunk seal itself, seldom the issue. Good Luck!
