98 Ranger 3.0 head light issue
Hi everyone
I have a 98 3.0 V6 Ranger and I'm having an issue with my passenger LOW BEAM head light. My high beam does work, but my low beam does not. Driver side lights and everything else works fine.
I tested the lamp plug with my volt meter. I used the plugs ground and the high beam hole to make sure I have a constant. High beams were not activated and I did not get a reading. I activated the high beams and I got a reading. OK good, the ground seems to work and I know I'm getting a proper reading. I go and test the low beam hole on the bulb connector and I also get a reading. I turn on the high beams and I no longer get a reading. Everything seems to work properly. What's going on here? If I'm getting a reading why is it not activating the bulb? I have 3 brand new bulbs that I'm trying this on.
To note, I tested the number 8 fuse slot and I COULD NOT get a reading. I don't know if it's my error or not. I tested the 4 slot (driver side low beam) and was able to get a reading with my volt meter after some time. How can I not get a reading in the fuse 8 housing while getting a reading from the low beam connector? Still, if I can get a reading at the low beam connector, why isn't it activating the bulb?
Thanks for any help!

when you click on high beams , the low beams lights are disabled , that is how they work
for legality reasons , you cannot have the low and high beam bulb filaments powered at the same time
the passenger side factory low beam connector has probably suffered heat damage and is no longer conducting electricity
this harness is what you need ( the headlight bulbs are now powered directly off of the alternator / when the engine is running ) battery connection
Buy Brite Box Smart Head Light Relay Harness Model H7.R1.9
simply connect the driver side headlight plug to this harness and then connect the ceramic headlight plugs to the bulbs
remove the fuses , then connect the battery connections , then replace the fuses and you are good to go

but if you just need new connectors
these are the best option ( ceramic )

personally i just cut off the fuse holders and solder eyelets to connect manual reset circuit breakers like these
20 Amp Manual Reset Circuit Breaker 12 or 24 Volt Right Angle Mount - WiringProducts
when fuse filaments heat up , they conduct less and less voltage and amperage
where as circuit breakers do not drop voltage and amperage over time

have you checked for continuity on the bulb pins themselves
your low beam filament may be blown but not look like it
long life head light bulbs do not produce the blue hue deposited on the inside glass like higher wattage bulbs do
what is the low beam voltage reading , your low beam relay may be failing ( possibility )

the relay could ( and i do mean could ) only be working enough to transfer enough voltage for 1 bulb
the bulb closest to the relay would receive power , the bulb further away would not receive power
i have seen this problem before on other vehicles , inserting a brand new relay solved the problems
again , what was the voltage reading from the passenger side low beam connector
relays do fail over time , they are not infalible

the reading should be 12.8 volts with ignition off
14.27 volts with engine running ( provided your + and - battery and ground cables are in condition
take a engine running voltage readiing at the battery positive connection ( negative to body ground )
if your engine is running and the reading is less than 12.8 volts
it is time to replace all of your positve and battery ground cables including the ground strap to firewall

dis connect both battery terminals
then unbolt the fuse panel from the inner kick panel
you are looking for corroded connections ( sometimes a white powder is a dead give away )
use a pin to poke through various points along the wire to determine how far the corrosion has traveled
( you may need to solder in a new length of wire if the corrosion has traveled a good distance along the actual copper wiring )

The battery is testing fine. All the right voltage. I just retested fuse #33 with high beams off and on, tested #4 when low beams were off and on, and tested #8 the same way. 33 and 4 (high beams and passenger low beam) are working properly, while 8 isn't doing anything.
After unbolting the inside fuse box, I'm having a hard time getting out, the wires through the firewall are not long enough for me to pull the whole thing out.

look at what color the # 4 low beam fuse wire is
pull out the headlight switch and test voltage the # 4 wire to the driver side low beam relay
relay is activated by the headlight switch , power then flows from the relay to the # 4 fuse , then to the headlight bulb
you will need to check the owners manual as to where the low beam relay is located

can you see what colour of wire is connected to fuse # 8
do you have an engine bay fuse panel / box ( if you do try that panel 1st ) for corroded connections
headlight switches are not directly connected to headlights , they are run through a relay then to the fuse then to the headlight bulb socket
basically when you turn on the headlights , the trigger wire flows voltage to the relay that engages contacts inside the relay , the relay then flows battery voltage to the numbered fuse and then on the headlight bulbs
if there is no low beam / high beam relays installed , then the passenger side contact inside the headlight switch has failed

i would recommend that you order and install that after market headlight wiring harness i linked
it will save a lot of grief in the long run ( since your driver side headlight bulb still receives power
the harness uses the driver side headlight bulb connector to trigger the relays that power the headlight bulbs
it is the relays that transmit power directly from the alternator ( when engine is running ) straight to the headlight bulbs
plus with that harness , you can now use higher wattage bulbs safely without burning up the harness because the bulb connector housings are ceramic and not plastic
i use 2 of them , 1 for each headlight and they work great

more expensive but well worth the cost

this is a picture of the engine bay fuse panel that also houses relays
the passenger side kick panel fuse panel should also house some relays
those small square black boxes are the factory relays

if you do locate the low beam relay
swap the low and high beam relays between each bank and see if that solves the problem
if it does not , then you have a wiring problem , which usually happens with the bulb connector itself
sometimes the connector is not water tight and can moisture get under the wire insulation and travel along the copper wiring and corrode it
