I have 2007 F350 that I am having issues with. Half way through vacation my A/C decided to only come out of the defrost vents and the turn signals don't work but hazards do. I replaced the flasher relay and multifunction switch to no avail. Checked wiring in steering column and nothing seems to be broken. Pulled about every fuse and nothing blown. At a loss as what to do next with this issue. As for the a/c issue I found a gray vacuum line detached by the oil fill. Reattached line, still nothing. Checked all other lines and they seem to be good. Vacuum pump didn't seem to be coming on so replaced that. I thought I had power to the pump but now not sure. Is there a fuse controlling that as well? Sorry for the long question, but I am at a loss as to where to go from here.
