In the steering wheel and passenger side dash.Due to the age of the vehicle probably doesn't have the curtain "side" airbags.The airbags were designed primarily for head on collisions. Here is some useful information to why the may have not deployed courtesy of http://www.asashop.org/autoinc/dec2001/collision.htm
How Air Bags Work
To have a frontal (driver or passenger) air bag deploy, certain criteria must be met. One of these criteria is that the frontal impact must be within a 60-degree window, occurring within 30 degrees from the vehicle's centerline. Another key element is that the crash forces are equivalent to a head-on collision with an immovable barrier at 10-15 miles per hour. Because a typical automobile accident only lasts about 0.125 (1/8th) of a second, air bags deploy within 15 to 20ms after the initial crash impact. To create a protective cushion between the occupant and the vehicle's interior, the air bag inflates at speeds up to 200 mph within approximately 30ms after impact. This allows the occupant to contact a fully inflated bag within approximately 45 to 50ms after the initial crash impact. Approximately 100ms after impact the bag deflates.
