When I turn on AC/heat in my 2002 Saab 9-5 2.3t; the air bag light warning comes on. When I turn the car off and start it again, it goes away. If I keep the AC/heat off, the light never comes on. Soon as I turn it on, air bag light comes back. Sometimes it will go away for 1-2 seconds but come right back on. It doesn't matter how long or short I drive, same symptoms.

Both of those ground beind the headlamp. It may be loose it's behind the left headlamp so remove the ground there clean it and reinstall make sure the bolt is tight. That may solve the problem. The a/c compressor and abs unit both ground there

The light is for Air Bag not ABS. ABS is fine and the light is fine, its the Air Bag light that comes on with AC/Heat blowing

Check the a/c ground like I said. The air bag ground is in the center console, check that as well. Any other problem with teh air bag shold have professional service. You can hurt yourself and your vehicle by not knowing what to do with these systems.

I will do that and see. I know air bag components are dangerous and can kill inexperienced person but I think this is electrical because it ONLY comes on with AC/heat blowing - it never comes on otherwise. Thank you
