The driver speaker cover comes off with Torx and after shining light through windshield, you will see two bulbs on a printed circuit film set apart from each other. You can reach them and twist and pull, clean contacts if bulbs not blown, replacement Sylvania 2721. There is also the reostat/dimmer knob that can be jiggled on dash, lower than the bulbs, each controling each bulb. I am in process of replacing mine with LED lights, which are brighter and come in colors as well. You just have to make sure the LED draws no more than 12 VDC as the alternator output is 14 VDC. Check out superbrightleds.com , there you will look for # 74 bulbs, which is same as 2721...I just came across the site today and thought, although your ????was a while ago, maybe this will give Saab Nation the ability to see at night....LOL

Assuming the battery is ok, no electricity is reaching the car circuits. First thing I would check is to make sure that your battery connections are good and tight. Next item is the battery properly grounded to chassis? If so, they you will have to get a schematic to trace the wiring and see just where the flow of electricity can be interrupted.
Check on the front panel where you see fuel consumption, outside temp etc that the botton that says black has not been pushed. If pushed no dash lights will come on and the panel screen for the outside temp etc will also be black. So give it a push and the lights should come back on.
have car scanned auto zone -advanced auto and some other auto stores will do this for free most likely one of your sensors is starting to go bad usually will activate at low speed under 10 mph as ur slowing down do check this problem early as abs can cause vehicle to stop longer
It seems that the bulbs went out or the ribbon cable that runs behind the instrument panel burned out check on a junkyard for a replacement instrument panel and replace it, verify that the truck you pull out the instrument cluster is the same year and the same model.
I have this problem too and my new Saab mechanic told me that I would probably need a new instrument cluster. He said a brand new one costs $2500 but that he would order me a used one from a car that had fewer miles than mine as you can set them back but not forward. He both diagnosed and temporarily "fixed" the problem by slamming his hand really hard on the dash over the panel and all the lights and gauges immediately started working fine....for now. I haven't had the work done yet (I have a 1998 Saab 900S with 130K) so if anyone has any other ideas about this I would love to know what they are. This issue with the gauges and dash lights has been happening on and off for over a YEAR and this is the first time someone has had any idea what it is. I already had my ignition switched replaced so we know that's not what it was. THANKS
