Hi Guys, Im new to this site and i think its a great site, Heres my problem and im really hoping someone has an answer, i only have high beams no low beams and when my daytime running lights are plugged in underneath, they wont turn off at all, I have tryed the fuses and changed them, tat didnt work, So for now i have unplugged the 3 prong at the front of the truck and i only can use high beams, any ideas, I have a 1998 for f150. Any help would be appreciated....Thank you

 

Did they go out at the same time, mine went out separately and it was the headlights, put new ones in and everything was great, don't know about the rest of the problems

 

They did go out at the same time, i think ill get new lights and see if thats going to take care of the problem...

 

Do you have that "auto lamp" feature on your headlight switch assembly? This is an "active" module with an integrated circuit and a couple of transistors, and as I've experienced, is subject to a logic freeze (and also wiped out 2 fuses, one of which was the chime, airbag sensor check and dash cluster). If you have this, rotate it to the "off" position (and keep it there). Worse case, disconnect the battery for a couple of minutes. That module could keep your low beams from coming on, and the steering column switch merely turned on the high beams. This happened to me last week!

 

before you go out and buy new light you should test them first. take the bulb out and wire it strait to the battery
