You will need to have your car's ECM (Computer) read by a OBD II scanner to determine what Trouble Code your ECM is giving so a mechanic can properly diagnose the problem. You can go to your local AutoZone store and they can pull the codes out of your ECM for no charge.
If you tolk about camshaft position sensor-YES.Located on a back side of the engine , next to the gear box.Have metal cover .Use diagnostic equipment to find the problem or code reader.I also had the same problem in my SAAB 95.In 6 monts time I have change two sensors.Made in China
The OBDII Scanner will turn the ignition key forward but don't start vehicle and turn all lights and radio off and heater off. And plug the scanner in. Then it will run the codes and tell you what code(s) are write them down. Then you will hit the erase button to reset your engine light. If the light goes back on you have a problem it should stay off up to 50 miles if not then have your vehicle checked out usually it could be your O2 sensors or a MAF Sensor "MASS AIR FLOW SENSOR" that is faulty and or your intake tubes are loose allowing too much air flow in to the engine if this happens your car will be running too lean.
you may have blown the head gasket.
or
check the coolant level,is it low?
if it is ok,check the fan switch on the radiator,change the thermostat,and check that the fan is working.
the fan has to work,saab engines run very hot.
there is a after run fan switch as well that measures engine compartment temperature,and can start the fan even with the car off,so be careful.
Don't know if it is any help but I had the same problem and it turned out to be the intercooler hose was split and sucking air. Fixed it and know problem now.
IF THE BULBS ARE OK CHECK THE HEADLIGHT MODULE(IT LOOKS LIKE A RELAY, ORANGE CASE I THINK) TRY WIGGLING IT,IM PRETTY SURE THATS IT. THEY GO BAD ALOT ON SAABS. IT SHOULD BE IN THE ENGINE CONPARTMENT
