Well, it is either the multi-function switch or the "smart" junction/fuse box. To test which it is, you need a piece of wire connected to a good ground. It needs to be long enough to reach the smart fuse box under the dash on the left side. Find a blue wire that connects to terminal twenty one, this wire also connects to the multi-function switch so you could trace it from there if needed, just be sure it connects to terminal twenty one. Turn the key on, turn the headlights to the headlight position, No low beams. Touch the wire jumper to the blue wire. If the lights come on now the multi-function switch is bad. If not then it is the "smart" junction box (it has a computer that turns on the lights and dims them inside it).
