Ok guy I have a airbag light on . It is the one in the cluster. The passengers light that you can cut on and off will not light up. About 4 months ago my horn won't work ,so I replaced the clock spring. That did fix the horn but not the air bag. So I would like to know if I replace the front impact sensors will I have to have the truck star scanned. And the airbag cluster use to come on when I had a drill or other tools in the passenger seat. Some times it wouldn't go off after tools were removed. So I am thanking I may need to replace that sensor also. What do you guys thank
