I had the same issue a couple of weeks ago. The brake lights were out, but the third light on the cab was working. Turn signals worked fine, but the hazards were erratic. I could not locate a fuse at all, nor does the factory service manual indicate a location. I removed the turn signal switch from the column, and ran the point to point circuit test on it, but found nothing wrong. I put it back in, plugged the harness back in, then everything worked again normally, and has ever since.
