Check the plug behind the drivers side turn signal. There is a small harness that plugs into a dummy plug that bypasses where the DRL
module would be. If that came unplugged that would cause the problem you are having. If that is not the issue then I would look at the multi function switch for the headlights, turn signals, wipers.
