myprizm 1 In my Corolla 2007 Air bag light comes on after about 10 seconds after starting engine. Called dealer, they charge $115 or more just for diagnosis. The guy told me that if the light is on the left of the dashboard that means that the issue is with driver side. Is that correct? When I just put the key to the ignition I have only one light, which by the way goes off after a while. Other symptoms are : Horn is working and the light is coming on even if I start the car from the window (nobody is sitting in). I checked both connectors under the seats and visually inspected cables but didn't see any obvious problems. I appreciate any comments and advise what my next steps should be.
