  •  Jon - Nice site! I too collect model Mercedes (among other makes) . I
    went to your service page but the links mentioned didn't appear, so I
     hope you Don't mind the email. I have a 1978 300D with 131K. Lately, the
     auto lo and auto high on the climate do not work. When pressed, no air
    comes through, no fan comes on, etc. I have the temp wheel set at 65.
     Turning the compressor on or off doesn't seem to make a difference.
     Every once in awhile, the lo and high do work, but hardly ever. The
     defrost does work, however, and the fan & compressor does blow cold in
     this mode. I'm guessing that a sensor of some kind may be at fault here,
     but don't know where to begin. . Any suggestions?

     Also, the power antenna motor no longer works. The antenna is stuck in
     mid-low height so reception is not good. I remember hearing once about a
     lower cost but still good quality replacement elect antenna. Any idea on
     availability  & where I could locate this?

     Thanks!
     Jeff



  • The climate control system on your car is fairly complicated. What
    you have is a vacuum leak of some kind. It could be in the climate control,
    but I would start with the door locks first. Under your hood over by the oil
    filter are all your van. lines. There are two yellow lines that connect to a
    yellow splitter. Disconnect the lines and plug the end that goes toward the
    engine. I use a golf tee.  Try your climate control and let me know what
    happens. JON
