Is there an ETR(evaporator temperature) switch on a 240D? I see a black cable going into the evaporator box but where it goes under the dash I can't tell. The setup is slightly different than a 300D which has a mechanical temperature switch on the outside of the evaporator box. On this 240D I am working on I can't get the vent temps below 44F because something other than the pressure switch seems to be cycling the compressor.
