Customer Question

I was rewiring my trailer connection and crisscrossed wired. I could not get it to wire up correct and so quit. However now my light and wipers will not work. I visually checked the fuses and they look good. What did I do. It is a 2008 kia optima.

Hello and welcome to JustAnswer!

I would first suspect a blown fuse but it could potentially be a wiring or module issue; all circuits that you should have been dealing with are fused so I wouldn't really expect anything but a blown fuse.

You've checked fuses in both boxes?
What specific wiring were you dealing with?
Was everything working correctly until lights were turned on or the brake was pressed?
