2007 328i....both headlight just quit working,not fuses.....any answers?

There are only diagrams for the 1988 onwards to 1992 models. They don't show a headlight fuse either.

No relay either. It is puzzling.

Did you just buy this truck?

Could be just fuse blown, or headlight bulb blown, if both ok, check headlight contactor.

The front control module controls all of that and they go bad all the time. It's bolted to the fuse box under the hood

Well I don't see a fuse or fuseable link for the headlight circuit.
In years past there was a circuit breaker built into the headlight switch for the headlights and fuses for everything else.
I would check the red wire on the switch for power first.
It could also be a problem with the dimmer switch.

Try checking both a; your fuses, and b; check your bulbs. You should have two fuse boxes, one under hood and one in or under the dash. Check those for bad, blown or weak fuses. And check your headlights bulbs for them being good and their connection. If this doesn't fix your problem, you may check out your highbeam switch.

Do you have tail ligts and side marker lights with drls on? if so you will have only dim headlights. Check fuses, I think the headlights are fused seperately.

check the headlight bulbs, it's quite possible they are both burnt out.

alright here is the fun part... look under the coolant recovery tank. Its hidden under there. First check your switch out before you remove the tank. Let me know how it goes I have had the same problem.

Check the earth wires have a good connection and are clean..
