82 300SD Heater blows warm at idle, not at speed

Re '82 300SD. Climate control switches blow air at normal rate (auto and full-on), but it only warms up at idle (e.g. stopped at traffice light). Otherwise it is cool but not cold. I replaced the thermostat; engine warms up quickly to operating temp. When fan turned off (not on auto or full on), I can feel nice warm air at side vents, so warm air seems to be in the hoses. But press the buttons and it's only cool air. Is this a monovalve issue? Something else? Thanks.

W123 83 300cd Leaking Trunk Lid

I am collecting water in the perforated area on the trunk lid. After a rain, when I open the trunk lid, water start pulling out from the holes in the under portion of the trunk lid, the trunk gasket is fixing good, I cannot figure out where the water is coming from and how it is getting in the perforated area. As soon as i open the trunk lid the water that was collected in the perforated portion of the trunk lid, start pouring into the trunk. I am open to any suggestions, there is no water in trunk well areas.

300-E - Horn not working.

I have a 1991 300E. I just recently purchased this car from a lady, and it needs lots of minor TLC.

Right now I am trying to figure out the horn. I have looked in both of the manuals I purchased for the car online and there is no information on the horns.

I did see some information that suggested you replace them, and silly me I did just that. Also cleaned up the area where they bolt to the frame in front of the radiator. Cleaned the wires up. But no sound comes forth.
