What's the deal? Volvo OD's don't work on Christmas? I can't believe there were three or four posts from yesterday all relating t OD's. On the way in to work this morning my OD (M46) disengaged on it's own. Light went out. I clicked it back in, it held for ten seconds, disengaged, light went out.
All the way in to work, I could press the button (not a slider), would sometimes hear a click, sometimes I wouldn't. Sometimes the click would be followed by OD engaging and the light coming on, sometimes it would click but nothing would happen, no light, no OD.
It appears that the OD light is working as it should, I pulled the shift knob off and checked the wires/spade connectors to the switch and they look fine. Does the intermittent "click" suggest relay behind the dash or OD switch on the trans?
