I have a 2006 ford mustang I just changed the
blinker switch that controls the blinkers and high
beam. And my high beams still won't come on. I've
tried clicking the lever back to turn them on and
won't come on. but if I hold the lever back they will
work. Need to know what I need to fix to get them
Go to the power distribution box under the hood and check/replace fuse #50 and relay #27. That should do it if everything else is okay.
