Ford Taurus SE: I have a 2003 Ford Taurus SE 8th VIN: U Both

Customer Question

I have a 2003 Ford Taurus SE 8th VIN: U
Both of the headlights are not working, but the parking lights turn on. Could you provide me with a wiring diagram or fuse box schematic? None of the fuses in the battery junction box were blown. I know there is a fuse box under the steering wheel as well. Thanks.

Hello. My name is ***** ***** I will be helping you today.Have you tried new bulbs or checked for power to the bulbs? It wouldnt be the first time I have seen both go at the same time.
Customer: replied 1 year ago.

No I haven't is there a fuse I could check first though?

Expert:  Wayne Crawford replied 1 year ago.
Just a moment. Let me pull up a diagram.
Expert:  Wayne Crawford replied 1 year ago.
In the under hood fuse box 19 and 21 and for the low beam headlights.I attached a wiring diagram for your reference.
Customer: replied 1 year ago.

this is the battery junction box, need the CENTRAL junction box.

Expert:  Wayne Crawford replied 1 year ago.
I dont understand. I didnt attach a fuse box diagram. I attached a headlight wiring diagram.
Expert:  Wayne Crawford replied 1 year ago.
Are you seeing a battery junction box diagram? If so I can repost it. I just pulled it up.. it was the same one I posted when I loaded it.
Customer: replied 1 year ago.

Disregard that. I found the fuses and checked them all. However, when I went to check the voltage at the lamps I found that the plug was fried. What would have caused this and what would be causing the other one to be out too? Thanks.

Expert:  Wayne Crawford replied 1 year ago.
Is the connector on the other one melted? What headlight do you have in there?
Customer: replied 1 year ago.

The other one is fine. the bulb i have in there appears to be fully intact. It is a Phillips HB5 9007 12V 65/55W DOT bulb

Expert:  Wayne Crawford replied 1 year ago.
As long as you got a good ground I would think it just had a bad connection and needs a new pigtail. On the other side Im not sure.. do you have power to it?
Customer: replied 1 year ago.

There is roughly 12 volts on the driver's side that appeared fried, but not getting any voltage at the light on the passenger side.

Expert:  Wayne Crawford replied 1 year ago.
Do you have voltage on both sides of the fuse?
Customer: replied 1 year ago.

yes 11.46 same as battery on both sides of both fuses 19 and 21 in the battery junction box.

Expert:  Wayne Crawford replied 1 year ago.
Check continuity from the right headlight to the fuse. Let me know what you get.
Customer: replied 1 year ago.

on the drivers side lamp I got the buzzer to sound which means it has less than 50 ohms of resistance. I got nothing from the passenger headlamp.

Expert:  Wayne Crawford replied 1 year ago.
Then you have an open in the wire between the two. At that point it comes down to good old fashioned wire chasing. Start at one end and probe the wire every so often and find out where you lose continuity/voltage.
