I went under my F150 and luckily caught it in time... The back side of the relay where it was touching the steel frame was corroded to the point I pushed my finger right through it into the electronic insides. The replacement I put in came with stand-off rubber bushings so the aluminum Relay does not come in contact with the steel frame.
