    I have the same problem on my 02 F350. Im curious, did you end up replacing the multifunction switch connector or the switch or both?Mine is all black at the connector and the two wires that control the hi/lo lamps get really warm. Not really looking forward to doing it.....

The multifunction switch that controls the wiper /turn signals,and high/low beam lights are very common for (when they get a lot of miles on them) for having problems.also I have seen a good number of these pickups that the connector (that plugs into the back of the multifunction switch)had lost the ability to properly hold the wire terminals into the connector causing a poor connection between the switch and the wiring. sometimes this can be verified without removing the column shrouds by (if equipped) tilting the tilt wheel up and down and see if the lights start working . hope this helps,thanks for using fixya

there should be a fuse and/or relay that operates the low beams, or try replacing the bulbs.

SOURCE: low beam headlights do not work

replace low beam bulbs, you tend to use these more than high beams and it is not uncommon for them to quit a same time. It happened on my camaro and on a friends trans am. I bought a 50.00 headlight switch only to find out it was both low beam headlights, which on a 1997 camaro is another 50.00 (25.00 each). I would try that before taking dah apart. Added note, at first I had ruled out the headlamp being bad, because i had just replaced one of them 3 months before this happened. I pulled in the driveway they worked, when I was ready to leave I only had high beam, but problem was solved with 2 new headlights.

Low beam headlight drivers side don`t work. high beam it works.

Check tour bulbs first and replace if blown. If OK then check wiring backwards from light to dip switch.

High beam headlights don't work, changed the bulbs, and checked the fuses, help

This is going to be a problem with your light switch or dimmer switch. Replace the light switch and see if that resolves the issue.

Have a Nissan pathfinder 2005... The high beams don't wonk. I changed the bulbs and they still don't function.. Any idea how to fix this problem?

Did you check the relays? or the High beam switch? Usually you can trace the wiring down from the switch to a harness at bottom of steering column use test light there too.Use a Test Light at the headlight connection make sure that you have power Low beam then test high beam. If you can't figure out use of Test light, it has a ground clip and a probe (Sharp end)Ground the clip on something metal (on car) use the probe to touch wire (one at a time) in the socket where the headlight connections. 1 wire is ground 1 is LOW beam and other is HIGH beam. may need a mechanic to check the switch. The light on the tester will light up IF you have 12 volts. NO LIGHT NO POWER!

Low beam head lights not working - The low beams, both stopped working. The high beams work fine. I checked the fuses and all 4 are good. I even swapped the low and high beam fises just in case. No...

if the fuses are good then you need to check for power and ground at the headlight plug that attaches to the headlight bulb if you have a good power and ground there and the connections are good then the bulbs are both no good.or if you can tell the bulbs are burnt out by looking at them then you don`t have to check powers and also can directly feed power and ground to the bulb and check both the terminals for high beam and low beam as you cannot tell which is which by looking at the terminals

The same bulb in a lot of applications controls both the high and low beam. Generally the low beam portion will burn out and for a short time you will be able to use the high beam only. I can't be certain which headlight switch that you checked, but the most common solution is to replace the headlight bulb. The bulb is on the inside of the headlight lense and is accessible by opening the hood and peeling back the rubber cover that covers up all of the headlamp apparatus. Depending on the model of vehicle they are mounted in there differently. Make sure and change both at the same time. It is generally cheaper to purchase new headlight bulbs as a (2) pack and it never fails if you change one the other will burn out in a week. Hope this helps
