ITMA (with question about mirrors)
Discussion
Looking from the mirror side of my mirror pods, there are two holes at opposite corners in the frame around the mirror. Looking inside these holes shows what appears to be corroded Phillips screw heads ... but they might be something else. I can't turn them, but don't want to put too much force behind it because of the evident corrosion.
Are these in fact screw heads, or (say) peened nuts or screw ends, or something else ... ?

He's right youknow! Note as well that the wires often get pulled off the dashboard joystick, usually when fiddling behind the centre console to fix something else! I have a drawing somewhere...

I can't get the O/S mirror to operate. I hear a click from the mirror when pressing the joystick up/down but not when pressing right/left. I think that the mirror glass might be a tad too tall as there is scuffing of the paint inside the pod at the bottom. I checked the wiring at the switch & joystick, it's OK. The N/S mirror works in both axes.
The 'bible' indicates that the mirror pod has to be removed (after removing the door trim) to access the innards, but the screws suggest there is access that way. Is that the case?
I've soaked the screws with WD40 and will try to ease them out today (in-between testing and labelling the fuses
). >> Edited by streaky on Saturday 16th August 19:09
The mirrors are an exercise in cheapness. Instead of using two motors (one each for up/ down and left/ right), there's one motor and a solenoid. The solenoid in effect pulls the motor pinion across between two racks, one for each axis. The clicking you can hear is the solenoid, so it appears the motor isn't running. Of course this means you lose both axes (if you get one and not the other, it's usually the solenoid).
The joystick has (from memory) six terminals. A couple of them are internally linked. By devious means, the terminals are linked in different combinations to give all permutations of forward/ reverse motor rotation, solenoid or no solenoid. The rocker switch merely breaks the motor feed to stop accidental operation of the motors. So it only needs to have one wire off to lose both axes of both mirrors.
I wrote a piece for tvrwedgepages but it's still awaiting Mike Bressington's attention. The tricky bit is figuring out which wire goes where on the joystick; that was the main purpose of the article.
On my car the mirror motor units are French made: the joystick and rocker are ex-Granada and the exact same electrical circuit is used on the SAAB 9000, suggesting a commonality with several other makers, in case you need spare parts.

My screws were rather worse for wear, but eventually came out. I replaced mine with longer raised countersunk stainless ones that now fit in the hole tidily. My mirror electrices don't work either, but a prod of the mirror glass is all that's needed to point them in the right direction...
