Mercedes 300SD 1983
Mercedes 300SD - 1983 - climate control wiring diagram ?
Hi Guys, I just bought a 300SD and my first job was to put in a new the AC compressor/line flushed and recharged. The compressor engages only if I jump wire it (connect it to a 12V terminal). The A/C blows cold! I suspect the climate control unit and possibly a relay gone kaput.. Has anybody got a wiring diagram of the system so I can debug it effectively. Don't worry I am quite familiar with electronics and circuit and I even have a friend who is an electrical engineer. I would by the manual but it will not get here in time I need the information.. Thanks, any help is greatly appreciated. ..
