The day time running light are not working and the passenger side high beam is not working. Do you have a digram of the electrical harness. The car is a 2001 HOnda Accord

This is usually caused by a failed front control module as this unit controls the lighting on the vehicle!

Hi Steven, I guess you have checked the fuses? Some time (and I'n not saying this is your problem) the fuses are wired in such a way that if one blows (and the fuse is on the earth side of the circuit) there will be an output, but the circuit will either use the earth through the the other bulb or fail to earth. I would also suggest having a look at the relays and their operation. Lastly, check the earth connections again. Regards John

check for a bad ground or check plug and back track wires with test light till you get power and fix the wire. Make sure you check for a good ground first. If all fails then run a new wire from the other low beam light to the non working one.

headligth relay is bad. replace

Make sure the high beam realay under the hood fuse box is working. You can swap the hi beam relay with the horn relay to test. The hi beam filiament in the bulb can be open too.

Day time running lights run low voltage to the high beam bulbs so it sounds to me like you need two new bulbs or you need to check the fuses and see if any need replaceing.

Passenger side high beam element burned out. DRL problem might be the emergency brake suppose to turn off when engaged. Slightly depressed will cause DRL not to work.

check the head lamp dimmer swicht

Well usually it's due to a missing or damaged grommet at the fire wall. There's a number of other ways to have a short like that too.

The problem with the DRL issue describd in the above posts is the DRl module(it needs to be replaced). The buzzing relay and intermittent on/off of passenger side DRl are indicators that the module needs to be replaced.
