Question about 2005 Pontiac Grand Prix

Moisture in truck, with check gas cap message on dash

I have a 2005 Pontiac grand prix. I seem to have a problem with quite a bit of moisture entering the trunk. It only seems to happen when i am driving in the rain. It is noticeably wetter on the drivers side. Since this has been happening i have also had a message on the dash to check my gas cap, even though the cap is secure.

The two are of course not related. Check the trunk seal for missing portion, tears, splits, etc. this has to be where the rain is coming in. You can check for leaks with a hose and climb in the trunk with a flashlight, having a trusty helper direct water to one area at a time to check for the leak. The gas cap light is probably on due to a defective evap. vent valve, which is located behind the left rear tire near fill tube for gas tank.

Check gas cap


You'll need to get the computer scanned for trouble codes.
Chances are there is a small leak in the EVAP system. Could be a valve or hose in addition to the gas cap.
