dash and headlights won't work?
So I fix one thing and something else goes wrong
I changed out the PCV valve hose on the car because the old one had a hole only unplugged one connection on the engine bay but plugged it back up after putting on the hose. So I drove my car later that night and my dash /tail lights wouldn't come on at all??!! 
I wasn't sure if changing the hose had anything to do with it or it was just a weird coincidence just makes me sick of fixing things all the time!! So I've been reading on the forum and I checked the fuses/relays all seem to be working fine not sure if its the switch? haven't had a chance to take it out to look yet. I've heard about some twilight function being able to bypass having to replace the switch but not sure how to use the twilight? I would be really glad if that was the case!! Thanks for feedback guys!

Twilight Sentinel (an option) only turns on the headlights when the ambient light is low. You can read your owners manual on this.
It seems like your Multifunction switch on the steering column may be the problem. Cycle that switch for headlights one or two dozen times and see if you can get things working again.
