Fantastic. This is a ground side controlled system. This means it gets power all the time and the paths to ground are controlled by the switches and or relays. What I need you to do is pull both bulbs and tell me if the re with black wire has a path to ground. I suspect it does not. If this is the case I am going to assume you have day time running lamps as an option. Try swapping the DRL relay with another relay and see if the path to ground has been restored.

Testimonial: "In the 2003 ford escape. With both bulbs out black with red wire gets ground n off position, low and high. The next or top wire does also. The right wire is not ground in any position. With one bulb in, black n red wire is ground in off and high positions, and hot in low beam. Next wires are hot in high or low position. All three are ground while off. Same results for either bulb."

You need a new headlight dimmer switch located on the steering column between the dash and the firewall

SOURCE: No low beam ,but have

Check for bad ground for low beam and bulb.

Also, check that the high beam works independently of the low beam for that mode.

SOURCE: 2005 Ford Focus ZX3 SES, the blue high beam

It sounds like you are confused about how your headlamp system is supposed to work. The DRL does not run on the High beam circuit, it runs on the low beam circuit. The fog lamps are supposed operate with the park lamps and also with the low beams, not the high beams. From your description, I would say that your system is operating as designed and you are having trouble telling High from Low. (Don't feel bad, that is why high beam indicators were invented in the first place.)

01 pt cruiser right high beam light won't work.


In the diagram for headlamps, the top wire is voltage, the bottom wire is ground. You can use a test light to check voltage and ground. To test ground, one end of test light touches battery voltage the other end touches ground wire terminal, if the lite comes on, the ground is good enough to lite the test light. You know how to check voltage with test light, correct?

Left operating headlight not working


the switch supplies power to the relays that switch on the lights according to the position you have it at
so on high beam there will be 2 high beam lights working
on low beam there will be 2 low beam lights working
back to passing lights or flashing head lights , both beams will work so the switch is the last item to consider
Now with only one side beam not working it comes back to the ground on that light for that bulb
remember that electricity follows the path of least resistance so it the ground is bad the current will ground out through another point including a light which will switch that light off or make it not work
remember the brakes light that flask when an indicator is used --same thing

Low beams dont work and only one high beam works


Do you know how to do voltage drop testing ? Leave the blubs in there sockets turn the low beams on , measure voltage on the power side , LH low beam yellow with black stripe an for the RH low beam dark blue wire . If you have battery voltage there, power side is good . Then check ground side both are yellow wires , test with lights on . if you see 6 volts , 12 volts .anything more then .03 millivolts you have a ground side problem . The lights ground through the light switch .
Low Beam
Voltage to the headlamp switch is available at all times from the HDLP SW fuse 7 through CKT 1940 (ORN). When the headlamp switch is turned to the HDLP position, the headlamp power relay coil is energized through CKT 352 (WHT). A signal is also sent to the body control module (BCM) that the headlamp switch is ON. When the headlamp switch is in the AUTO or PARK position, the ambient light sensor (located in the right speaker grill) senses either daylight or darkness and sends the signal to the BCM. When the Ambient Light Sensor detects a dark condition, the BCM produces a signal that will energize the headlamp power relay through CKT 352. The relay coil is grounded through terminal F7 connector 2 of the underhood fuse block to CKT 350 (BLK) to G102. When the headlamp power relay is energized the relay supplies power to the LT HDLP and RT HDLP fuses. The RH low beam headlamp receives current through CKT 198 (DK BLU) from the RT HDLP fuse. The LH low beam headlamp receives current through CKT 712 (YEL/BLK) from the LT HDLP fuse. Both headlamp low beam bulbs are grounded by CKT 524 (PPL) through the underhood fuse block to the multifunction switch (low position) contacts through CKT 10 (YEL) to the headlamp grounding relay in the body relay block through the normally closed contacts to CKT 1850 (BLK) to G200.

2004 Pontiac Grand Am High Beams and Fog lights do not work


Check the relay that powers the high beam, if memory serves me the relay is shared between those two circuits.You can swap the relay with a known good relay to prove if that is the issue.

You can not have High Beams on and FOG LIGHTS at the same time. The Body Control Module controls this. You may have a bad Body control Module

Did you check the ground wire for that light? Using your voltmeter, put the positive probe on the battery terminal and your negative lead to the pin/socket that provides ground for the lamp. If you are reading 0 volts, you need to check the ground wire for proper grounding.

Lights---low beams are blowing out, and often I have no low beams, but can get the high beams. Fog lights work. Have had two new bulbs in four weeks.


You may have defective bulb sockets that may have overheated and are now deformed or corroded. Replacement socket pigtails are available at auto centers or parts store. Recommend getting ceramic sockets, these will not deform.
