2000 Expeditin 5.4 2wheel drive

Everything thing on the left side of my car seems to be failing.

First my headlights die, then my seat controls and pedal extender stop working, then my taillights work on and off.

But get this!


If I am driving my car and I engage my high beams only the whole damn car turns off immediately. It does this while sitting or driving, engage high beams and car shuts off.

Tell me this happens a lot and is a common fix.
