So here is an interesting problem. I have a 1994 F-250 and was driving the other night, tried to put on high beams and nothing. The next morning I went to investigate and found that the 30 amp fuse under the hood which apparently controls them was blown. After some trial and error it looks like just putting on High beams doesn't blow the fuse nor does it turn them on. Its when I pull the multi-function switch back to flash the high beams does the fuse blow. I pulled the bulbs and the seem fine, nothing that would blow a fuse and I tried swapping out the multi-function switch hoping for a quick fix. Unfortunately no luck. I must have a short somewhere but cant figure out where nor can I find a wiring diagram. Just wondering if anyone out there has ever encountered something like this or maybe has a schematic I could follow?
