On my E350 I have had only high on the blower motor for about a year ( didn't feel like looking at it). so I pulled the old resistor out and could not get the plug out of the resistor. I finally got it apart and it is rusted and corroded beyond use. Has anyone had this problem on an F-series? and can you get just the plug end from ford or do I have to junk yard the harness and splice in? I assume the plugs are the same truck to van but the harness is obviously different??? (I'm am posting in here b/c of the year and that the van forum sees so little traffic.
