I've been trying to chase down why some lights are on my dash but I can't seem to figure them out. My car is a 97 Z28 for reference. One day after cruising, my air bag light came on as I parked and hasn't gone out since. I also have a security light on and my e-brake light doesn't go out when I put the e-brake down. Are they all tied together somehow? Prior to to the air bag light coming on I could arm my security system with my key fob and the red light under the dash pad would blink, but now when I arm it the horn honks like normal, but no light. I do believe the BCM has been replaced before so maybe that has something to do with it. Any ideas?
