Question about Cars & Trucks
If its both front windows its prob a supply fault so check fusebox. If its an individual unit, could be switch, power supply or motor...even loom breakage between post and door.
I would get it scanned with diagnostic equipment first to pinpoint the area then look from there.
Dont just start changing parts, you will cause more confusion.

there should be a switch right on the master window switch that may be "on" to prevent anyone but the driver to operate windows. is this car a convertable? is the switch between the seats in center console? do you have an owners manual? it may have it in there. i will try to find more info. for you if there is no "lock out".

Try buying one of the manuals listed on ebay , the guy is a
real gent and the manual is a fantastic help. Motros from Saab are not
cheap but if the tonneau motor needs replacing, try here

CD manual can be found here http://cgi.ebay.co.uk/SAAB-900-CONVERTIBLE-HOOD-REPAIR-TROUBLESHOOT-MANUAL_W0QQitemZ220365143328QQcmdZViewItemQQptZUK_CarParts_Vehicles_Manuals_Litterature_ET?hash=item334ec93d20&_trksid=p4634.c0.m14.l1262&_trkparms=|301%3A0|293%3A1|294%3A30

sounds like your heater core has a leak in it. take your sunroof off and get some rubber revitalizer at a glass shop. Try cleaning it and using the rubber rejuvenator on it.

First, check the fuses for the hydraulic motor; if they're blown, replace and monitor (why did they blow? Perhaps an overload, or ...) These fuses are located in the engine bay on top of the fender by the front right wheel housing.
Next check the voltage supply to the top switch, possibly a loose connection or broken wire.
Also check relays C (raising top) and D (lowering top) under the rear seat.
Lastly check for voltage at the pump, also under the rear seat, when the switch is actuated, and that the voltage polarity reverses when the switch is actuated the other way (up or down).
After that, it's a hydraulic/mechanical problem. Check the fluid level in the pump reservoir (use SAAB fluid to top up if low) Fluid level should be at the upper marker with top down, and at the lower marker with top up.
Check behind the rear seat side panels that the piston shaft is still properly attached to the roof mechanism bracket at one end, and the piston itself is still firmly attached to the body. Look for any leakage from the system.
If all tests out OK and looks good under the rear seat and behind the side panels, then there is the possibility that the piston seals have failed and the fluid is just circulating around without activating the piston. Pistons are available (http://www.convertibletopguys.com/cgi-local/displaycat.cgi?cat=584 - scroll down) but the entire system should be removed to avoid getting hydraulic fluid on the interior.
However, that fact that you can operate the hood using the bypass valve (manually) would indicate that the hydraulics are likely OK, and that it's probably an electrical or mechanical problem.
