switches are not lighting up when I turn my headlights and dimmer switch is not working on I've already replaced the headlight and dimmer switch still not working. Truck is a 2015 VN daycab any ideas would help!
try checking the fuses first as stupid of a suggestion as that is make sure all power is coming to you light contol module should be right under fuse box before you do this try to disconnect the batteries for about 30 and reintall them it happens sometimes the light control module has a brain fart
