and now its wierd my turn signals and brake lights work when the hazard button is pressed in?? help!

 

check the hazard relay

 

i replaced it and still nothing?

 

How about your grounds? I recently heard of a very strange issue caused by a bad group of grounds behind a headlight.

 

Multifuntion switch?

 

That would be my guess due to the fact that signals work if hazard switch is on
