Q: this could also be your battery - especially if its the original. the light will illuminate if the air bag circuit has insufficient voltage and batteries dont work well outside of normal operating tempartures. many autoparts stores will test your battery free of charge weve had some frigid cold temperatures in eastern pennsylvania lately im really starting to hate winter and my 98 grand caravan has been getting a bit balky lately. the engine doesnt start with the first turn of the key in the morning it doesnt do anything at all. usually the engine turns on the second or third try and starts right up. also the air bag light is staying on for 8-10 seconds. it usually is only on for a second or two. is this likely a problem with the ignition switch battery tia jon .
