Hi I managed to break the my power mirror just after getting my 2005 Jazz SE, and I'm considering taking it apart to fix it, since finding a replacement in the same colour is proving a bit difficult. I broke the flat inside top of the stand tube - the bit that lies horizontally under and is connected to the rotating mirror part by three bolts, and which has a hole for the cable to go through. The mirror crunched into a wheely bin when I was reversing and the part snapped in a triangle around the bolts, leaving the mirror itself dangling off the stand tube.
I've had a look at the diagrams posted below, as well as a diagram on
partsbase, neither of which show the piece I'm talking about (since it's normally hidden), but I know the housing, the electrics and the turning mechanism are all good because I used hot gun glue as a temporary fix and everything worked. I think I can attach it back together again so long as I can get at it from the other side, which means dismantling the door etc., although I might try unclipping the mirror first, to see if that gives me enough access to manipulate a gluing putty like
sugru to do the same job as the glue but longer-lasting.
