Question about 1993 Saab 900
The switch block can be pried out of the console with a screwdriver applied to the rear end of the block. Individual switches are not replaceable; the block is replaced as a whole. The lines connect to the block in a connector plug. Jumping them in a convertible is easier than in the other cars, as there is no lockout for the rear windows in the centre console switch. Your best option is to bite the bullet and replace the switch block either from an on-line source such as eEuroparts for about $200 US, or a wrecker.
Lines 18 & 19 are for the left front window,
lines 6 & 7 are for the right front window,
lines 13 & 14 are for the left rear,
lines1 & 2 are for the right rear, and
line 9 is the lock-out for the rear windows; I believe positive voltage applied constantly to this line locks out the rear windows, so leaving it un-powered won't hurt.
Polarity determines whether the window goes up or down; a trial and error situation. Use this info to get them up, then replace the switch block!
