I have a 1980 300sd that is dripping a little water on my feet. Last time, I mentioned it to the mechanic while it was in for something else and he said he blew out the drain with the air compressor. The leak stopped. Now it has started again with our heavy rains and I only found the drain on the drivers site near the hood hinge but did not see one on the other side. Don't know if they have them in the rear too.

My 240d is not driven much and stored in the garage but after all these years, any drains that it has are probably plugged.

I picked up a piece of used bicycle brake cable and it went through the front drain on the 300sd but started delaminating so I am going to solder both ends tomorrow. It seemed to work well.

Is there a book or site that might show where the drains are located?
