I have a `94 Bronco and have noticed the seatbelt light flashing off and on. I think it is giving me a code because I have kept my eye on it and the blinks are not consistant. Like it blinks 3 times and pauses then blnks 4 times and a longer pause. Any ideas? I have also heard a different buzzer sound coming from the cab if I don't turn the ignition off all the way. Any help is greatly appreciated.
