Saab 900s it doesn't crank, the onboard/in dash diagnostic doesnt turn on, basically there is no difference between the key being in the off position or on position.

SOURCE: The Key won't turn in the ignition

The more you use your key, the more the key will wear down overtime. Eventually (especially with car keys) the key will not match up to your tumblers in the lock, and will intermittently not work, and eventually not turn at all. Do you have a spare? if so use it see if it works, then have a copy made. If you don't, call the dealership, have them make you another key, or call a locksmith.

Now if the key won't come out of the ignition, that's a whole other issue, but it doesn't sound like this is the case. Hope this helps you out, good luck!

I'm afraid if you don't have the code, you will have to take it to a local dealer or specialist radio store to have it re-coded.

Fortunately, it's not expensive.

There are lots of sensors in your car that tell the Airbag Module that you are in the seat.
The seatbelts also have sensors in them and are known for going bad. Run down to your local autozone and they will have something to hook up to it to find the code that the Airbag set.That will lead you in the dirrection you need to look in. (Important) YOUR AIRBAG WILL NOT DEPLOY WHILE THE LIGHT IS ON IF YOU ARE IN A ACCIDENT

SOURCE: where is the thermostat in a 900s oh. 97 saab 900S

Oil change interval has nothing to do with operating temperature. If your coolant is full, feel the upper radiator hose, when the vehicle is up to temp. if cool , thermostat is back from that hose,

Look for air bleeds, and read owners manual, some cars have coolant bleeds. Also, heater on high when filling coolant or risk bubbles...

My thought is that your fans may not be kicking in. They should cycle on and keep temp low enough. test them.
