The little panel next to your steering wheel where the headlight level switch is, get a credit card under the bottom edge and pull the whole little panel out, its not hard to do. Then you should have a blank wire with a black plastic thing on the end (resistor). Give it a wiggle / pull it off blow it out, put it back on and see if that works. I ended up buying another panel with the dimmer switch on because its a feature on the car that isn't being used.
The dimmer switch is a switch that allows you to dim the dashboard lights when the lights are on so you can set how bright you want them.
