When i pull my switch out to turn on my headlights my park lights dont come on. If I wiggle switch then they come on but I lose the headlights. Switch is bad right? Thats what I thought so i replaced it. Same problem. Any advice?

yeah get a ford tech to work on it

 

I'm afraid I'm starting to sound like a broken record, but you've probably got a short, most likely in the plug that goes into the switch - that's why wiggling changes the symptom.
