Well yesterday after workI went to start my car, it was cold, started right up but the horn was stuck on. After anything to pull fuses it wouldn't stop for 5 minutes. Then I hit the horn again and this time it stopped. But on the drive home the needles were freaking out, bouncing all over and stuff. Ad the airbag like, seat belt, security, service vehicle soon, battery, and a few other lights were coming on and off. So I get home and after a few hours go out ad start it, everything is fine. Has been since then, except the airbag light flashes a few extra Times on start up now. I have no idea what happened, any ideas?
