This has been happening for a while but I noticed it's got to the point now where instead of the clock seeming to randomly have no power now if any door is open the clock goes off (display goes dark) and the red door-open warning light doesn't light up at all. The clock still seems to be 'stopping' at random as well (ie. I'll turn on ignition and the clock's 'lost' it's time).
Note it's a RHD 80, with no door chime thingy. I am trying to understand the schematics and how the door switch and warning light circuit interacts with the clock circuit.
My feeling is that there's an earth wire going/gone bad. The door switch and interior light circuit is fed from the 'dome' fuse which is itself fed from the power junction box (which I think is the one in the engine bay).
The clock has power from two places - one is a feed that enables the display via the ignition switch the other is what I think is it's permanent power (to keep clock 'ticking') from the 'dome' fuse.
I don't have a spare clock module otherwise I'd just replace it and see if that's the answer. Clock for my 80 is 83910-60040. It's the basic one with only three buttons. Amayama today is quoting about A$430 to get a new one! Can get used ones for about A$100.
I've closely inspected the two aggregated earth points at the inside bottom of each a-pillar and all is good. Before I completely pull the dash fascia and get at the wiring to the instruments, clock, etc. is there anything else worth inspecting?
