:( '97 K3500 6.5TD 5Spd Crewcab Dually. On way home Sun. night had heat at max and heater fan on high to clear windows, smelled hot electrical smell, stopped to check it out, but found nothing. Turned fan back on but inoperative on all speeds. Arriving home, no courtesy lights when doors open. Checked all fuses, ctsy light fuse blown. Tried to replace fuse, but pops instantly, even if no door switches are triggered. Gave up for then and when I hit the door lock switch, the lights came on momentarily! They come on every time you hit the door lock sw. Any ideas on where to start on these seemingly unrelated problems? Thanks, John.
