After I successfully replaced the heater core in my 1993 Dodge Dynasty LE (with a 3.0L V6 and four speed automatic), the air bag light stays on all the time. I did take out the air bag "brain box" in order to move the dash out of the way, to get the heater box away from the firewall, but I think I put it back exactly the way it came out, when it worked OK. I have looked a lot of places for service info on this subject, but it seems to be a big secret for dealers only! I could not find a schematic or wiring diagram, even on ALLDATA (which I can access through our local library). The heater works good now, but the airbag warning light stays on constantly, except for a momentary blink off, right at startup. I've been reparing cars, trucks, busses and motorcycles for over many years - but that Dynasty airbag problem has me baffled! Does anybody have or know of any diagnostic procedures for finding the exact problem, other than paying a dealer to fix it? The clockspring in the steering column is just fine! Thanks.
