I have a '91 Eddie Bauer and I don't know if my answer applies to a 93 model but get an electrician to check your dip/high beam and indicator unit on the steering column. I replaced mine and the problem of no dimmed headlights was fixed. The light switch always seems to run hot with lights on.
Probably a short SOMEWHERE. You have to trace the wires to find it.
i would have the light switch checked to see if it is faulty
It can be the dimmer switch. It needs to be checked out./ A test light will check for voltage.
Sense you are going the speed of light the lights would not come on but the switch will still work.
I would go to the high beam switch next (test not replace)
To travel at the speed of light you would have to BE light so i guess you would became an even brighter light The switch to turn on the lights will work but no light will come on as you are already at that speed
With most vehicles you can turn on the parking lights or the headlights and the dash illumination lights light up without turning on the ignition switch.
I would start with replacing the head light switch
bad light switch.
the dimmer switch is bad
Your headlights would come on and the light would speed ahead of the car at 186,282 miles per second.
This is a wiring issue. If the switch were the issue, the light would not turn on at all. Sounds like something is wired backwards, or there is a cross short. If there is a short to ground, you will be blowing fuses and possibly burning up relays. Consult your vehicle's wiring diagram to ensure the aftermarket headlights are wired correctly.
The headlights go up and down when you turn the headlights on. If they are not going up or down they may be disconnected from the motor. You would have to take the headlights out to see if they are disconnected or not.
its on the left turn signal switch, at the end is the headlights, then one in is the fog lights, you twist it just like you would the headlights
The car has automatic headlights....they go on and off when it gets light or dark out...they will also stay on for up to 3mins after you shut the car off depending on how the twilight sentenal switch is adjusted. And to take out the headlight switch in the door you have to take apart the door pannel
The headlight fixture probably contains moisture on the inside. When the headlights are "on", the moisture clouds the light beam, diffusing the light.
It could be a fuse, a relay the switch
I would suspect the dimmer switch or "combination switch".
If you leaned out of your car and meaured the speed of the light coming out of the headlights, you would find that it's leaving you at the speed of light.
Yes both headlights can burn out at the same time, I had it happen once, it is rare. If both high and low beams are out, then I would think that it might be the switch. You could get a cheap test light and check the plug to see if there is current to the lights.
The switch or the relay, check the cheapest, or simplest thing first, which could be the relay, but the symptom points more to the switch.
The light beam would leave the front of them at the speed of light.
I would replace the headlight switch as Ford has had their share of these problems.
Switch? both headlights?
It sounds like a blown fuse or a bad head light switch
I would check the rear bulbs. I just had this issue and it ended up my brother had used the wrong bulb, and odd enough it caused the brake lights to stay on with headlights. When headlights were not on and you applied the brakes the dash would light and brake lights worked. Strange, HUH? I must admit before this revelation, I replaced headlight switch and brake switch, with no avail.
