The gas flap on my 1981 380sl never locked, so i just assumed it wasn't supposed to. I just read, however, that it does have a vacuum switch, so I guess it was broken when i bought the car, since the trunk switch seems to be on the same line and works fine.
Assuming i'm rigth, can anyone tell me where the gas flap vacuum switch is located and how hard it is to replace.
Thanks very much.
