When I took my car from winter storage and had annual inspection done, mechanic found water in bottom part of trunk. Took it to dealer who said infiltration was due from blocked drain tube on drivers side of trunk. He said they sent pressured air inside drain opening and this resolved problem. Well after getting home and washing car 4 days later, I still have infiltration. I took out my air compressor and sent pressured air on both sides of trunk drains and watered the trunk again. Verified, and water was again visible. Does anyone have this problem, and if so, what fixed it?

 

remove all the covers and do the leak test again. see where exactly the water is coming in from.

 

Well drain tubes were not clogged and a closer inspection of the trunk revealed that one the trunk seals, approximately 1inch of it had let go. Now will go to a dealer to have it sealed properly and hope this will fix the water infiltration once and for all.
