SLK/R170: Water drain cleaning
One side seems to be clogged and overflows moisture into the trunk, not in any major quantities, enough to make the alarm go off randomly till it dries off.
It came to light last week when we had some heavy rains in Southern California, all I did was to park it in the garage and air it and it solved the problem, the drain is still clogged and I need to clean it.
Any advise would be helpful
