Hey guys i'm new here. Just bought a grand prix gt for a really good price only to realize why afterward. Front left signal light doesn't work and neither does the trunk button. I did some investigating and noticed the problem is in the firewall. The guy drilled a hole into the firewall on the passenger side and there seems to be some broken wires in there. I cannot see the wires but I put a screwdriver in the hole and the trunk popped open so I know thats the problem. So question guys....How do i go about fixing this?
