Q. I have a 2012 Camry that I love, but I just found out it has a leak in the trunk. It looks like some mold has started forming on the contents. How can I find where the leak is and fix it? Is this a job for an auto body shop?

A. If the car has a moonroof, check the drain. If you take out all of the padding there is a blue plastic line that runs from the moonroof into the trunk and exits out of the rear wheel well. Other possibilities include a rear window leak, poor seals on the trunk lid, or even the taillights. If the car was in a crash, a body seal could have been repaired improperly. A body shop or general repair shop could certainly take a look at the problem. In some cases they may call in someone who specializes in wind and water leaks.
