Seatbelt and Door Alarms 2003 F-150
#3
Turn key to start position (not running) wait for the seat belt indicator to go off (about 1 minute) the next step must be done within 50 seconds after the belt reminder goes off. Buckle then unbuckle the seat belt 9 times ending on unbuckled. The air bag indicator will be turned on for 3 seconds. Within about 7 seconds of the air bag light going off buckle and unbuckle the seat belt again this will disable the belt reminder. As a confirmation the belt indicator will flash 4 times per second for 3 seconds. Hope this helps this is straight out of the owners guide.

My 99 seat belt alarm randomly goes off weather I have it on or not. Is there a way to disable it so it can't anymore. I tried to do it the way above but the light doesn't come on when I turn the key on?
