I found my passenger side rugs are drenched went to the dealer who "believes" it may be a a hose connected from the sunroof that is clogged and I am responsible for the diagnostic fee. I researched online and found several blogs with same problem. After the diagnostic fee I would also be responsible for the unclogging "repair" fee. I looked through the owners manual and there is NO indication that this hose is part of regular maintenance. How else would I know this hose needs to be unclogged and how do I unclog, there is no related information in the manual. I strongly believe if it isn't part of maintenance how else are you aware of this issue ? Should I cover my car with tarp, park it indoors 2407 so that no debris clogs up the hose? Help
