The headlights on my 93 Dodge Dakota LE have stopped working, both high and low beam. All other lights do seem to be working. This happened a few months ago and it turned out to be a broken wire in the steering column where the wiring bundle connects to the dimmer switch/turn signal/wiper module. This does not seem to be the problem this time. The wire and its connector seem to be holding.
I do have both sets of lights when I hold back the dimmer switch lever, so I know there is power going to the lights.
A mechanic friend suggested that I change the dimmer switch module, so I did. Didn't fix the problem.
Another person has suggested that I change the headlight relay. I can't find it. I checked the PDC box, whatever it is called, that is mounted near the headlights and battery. Nothing there. Also I cannot find any mention of the headlight relay location in any of the online forums including this one.
Can anyone tell me if this vehicle has such a device and where it is definitely located?

 

There is no realy for the headlights. From factory they should have done it to reduce the amp load on the switches. Most likely it is a bad head light switch or the multi-functioning switch (for the turns and high and low beam switch).

 

Headlights on mine kept flashing and burning out switches. I finally replaced the switch and harness for it. It has been fine since. The harness seems to be the issue

 

Thanks botrod! This is a useful piece of information.
