My daughters and I have recently purchased a 1973 Mercedes SL. Very cute but very hot. We can't turn off the heat! We know something is stuck on. We are looking for a manual that would describe how to at least disconnect the heater for now. We have been to the library and came across the MB manual but it only discusses engines. I have researched EBAY and see several manuals but gosh, what type of manual will cover everything? I bid on a Haynes manual but now that I saw the library manual I am thinking that it too will not cover the issues we need addressed. Besides the heater the interior dash lights don't work. There are other items that are all non-engine related. Any help would be most appreciated. Thank you
