    Did you check where the snow plow light wiring harness connects with the factory light harness? Do they work without the plow plugged in? It could be something as simple as a disconnected plug or a corroded wire or a bad ground. Hope this helps! Keith

    has the lights worked in the past or is this a new install ? my buddy just transferred his plow from one truck to another and there is a connector by the relays that can go on two ways the connector has 2 wires going to it one is white /yellow and the other is red/yellow. if you have the 2 headlamp system you need the the white /yellow wire to match up to the red/yellow wire on the other connector( or reverse orientations ). if you have the have the 4 light system match the like colored wires together on the connector. figured it out after an hour of checking all the connection and moving relays around.

    Here is what the dealer told me. they have to reset the codes and my lights came back. The problem is that if your lights are on when u hook the plow it will shock the systems and the dodge built in security trips a code. This is NOT a fuse it needs to have theh codes reset. Mine does it all the time and as of two days ago this it what they told me is causing the problem. The fix leave your headlights off when hooking the plow.
