Ok i just bought a 95 lt1 m6 camaro and driving home the other night from a friends house it started to rain so i went to turn my wipers on and they didn't work. I was like ok w/e fuse is burnt out or something so when i get home i turned my headlights off and all of the sudden my wipers turned on. So i played with it for a while and my wipers work while the head lights are off and when the park lights are on but the mineute i turn my head lights on they quit working. Sorry if this was a bit long but i have no clue when it comes to wiring any help would be greatly appreciated!!!!!

 

Your going to have to get yourself a wiring diagram, you got a couple wires crossed...

 

Sounds like one of them for a Relay is messed up..
