I recently found my 95 S320L's door closing aids don't work properly- 3 out of the 4 doors can't close. It seems that the pump is not 'POWERFUL' enough to close the doors. However, the trunk's closing assist works fine. I found the fuse box in the trunk but can anyone tell me which fuse is the #9 one? I just installed a new battery (standard 100Ah one) but I used a lower 'A' one for a week to replace my old flat one. Dose it affect the pump's operation?? Any advice appreciated !!
