Hi I just purchased a 2004 Impala from a bud of mine. The car is great except right before he sold it he had work done on it. He says after he got it out the shop his parking headlights wouldn't turn off and kill the battery. He installed halos which along with the blinker lights are the lights that stay on. I thought I fixed the problem when I found a blown front park headlight fuse and replaced it. A few hours later the lights stayed on again and I found the new fuse blown as well. Any ideas on what I should do thanks
