Low beams headlights do not work on 2010 Sprinter freightliner

SOURCE: 2003 GMC Envoy Low beam headlights will not work.

I would start by checking the headlight relay and headlight fuse.  You also may wanna check to make sure the bulbs aren't blown out.  If those parts check out to be fine and in working order, you may need to replace the turn signal assembly in the steering column.  This part controls the hi/low beams.  This may sound crazy but, when GM wired their older trucks, they wired the headlights to go from the battery, to the hi/low beam switch, then to the headlight switch (to the left of the steering wheel) then out to the light bulbs.  You can kind of test to see if this part is good by making a fist and (with your headlights on) gently hitting the plastic cover for your steering column that is right behind your actual steering wheel.  This could cause your headlights to flicker on and off.  It's not 100% guarenteed that this method will work, but it may.  
Any questions, just ask!

Headlight Switch itself If Not then this Very Well May be in your Multifunction Switch

You need to start by checking the fuse for your headlights (low beams). The DRL could be be bad, but I have not seen them go out very often.

SOURCE: 2004 Envoy, low beam headlights turn off on their own.

the daytime running light module is no good.,or the relay is overheating and cutting out and comes back on when cool.get some freeze spray from an electronic supplier and spray the suspect component when it stops working.the -60f will make it appear fast..cheers

Check your headlamp relays under the hood, should be located on either the L/H or R/H fender well , could be inside a black plastic box labled fuses and relays... there will be a label on the underside of the lid to this box locate the relays as per lables... please rate my help thanks...
