My ML320 central locking system seems to work.... except for the rear door. It does not lock. I checked fuses - all seemed fine. I could feel the 2 relays in the fuse box clicking when I lock and unlock. When I lock I do not get the 1 time blinking of the lights. Had some trouble with the rear door mechanical mechanism not long ago... not sure what it was but it seemed to be locked in the closed position, when I tried to close the door it was hitting the latch. Pried it open, it has worked since. Perhaps I broke something. Any ideas?
Thank in advance.
