I have a 2003 ford ranger and the #2fuse inside panel that is for the blower motor, reverse lights and the passenger air bag deactivate switch keeps blowing. when I put a new fuse in the air bag light blinks 3 times stops then 2 times stops. it does this over and over again. the fuse only last from 2 minutes to 1 daY. would any one know what to check. I have unplugged the blower motor, the air bags. and the wire harness at the end of the bed
