I replaced the radiator and hood on my 98 Windstar (ok, first I drove the
car into the car in front of me). In order to replace the radiator, I
removed the cross member in front including unplugging what I assume is 2
air bag sensors. The car now flashes the air bag light 4 times for the
first few minutes of operation.
I didn't notice the warning light until after I unplugged the sensors, and
I'm pretty sure I plugged them both back in well.
The air bags didn't deploy when I hit the car in front of me.
