This question is about a 93 chevy P30 "bread truck" truck that I am having issues with. I know this is not the forum for it but ya'll have helped with my 61 panel so I hope you can help. If need be please P M if it needs to stay off this forum.

Question is, can the ignition switch cause the battery side of the fuse block to cut out? The fuse block is pretty basic in this truck since there are very few items in the truck. The ignition is loose, when shut off the truck runs for a few seconds before it shuts off,the horn sticks on and the left side of the fuse block is out. The switched side is fine. I am also have an issue with the heater fuse tripping. My thought is its from the ignition switch or in the wiring from the column harness to the fuse block. Any thoughts?
