Why are both low beams on my Mazda 3 not working?

I have a 08 Mazda 3. Both of my low beam headlights quit working at the same time. I checked the fuses both under the dash and hood and they are all good. Checked volts at the headlight connection and there is none. I have seen a lot of posts regarding this but none that have a fix.

What does it mean when your low beams dont work?

If the high beams work, that means power is getting to the Passenger Junction Box (aka the “fuse box” under the glove box). From there is splits to the High and Low headlight relays, through the headlight fuses, then to the headlights.

Why are the headlights on my Mazda CX-7 not working?

Headlight bulbs have burned out every 6 months since we bought the vehicle in 2010. Over the past few years, the lenses have fogged up to the point headlights are worthless. Took the vehicle to the dealer, one seal is bad and the other side has melted, cost of repair is nearly $2,000.

How does a DRL work on a Mazda 3?

The DRLs are the high beam bulbs operated at about 7 volts through the canbus. As LEDs draw a lot less power, the canbus doesn’t see them so they don’t work, just like LEDs used for signal lights tend to hyperflash. You need to use the proper harness adapter to make the LED highbeams work correctly in the Mazda 3.

Where is the fog relay on a Mazda3?

Drat, didn’t catch that when I was editing.. it is J-03. (The head light switch has wires on both of the connectors, at first I though the wire was on the other connector). As I said above though.. the fog relay is driven by the power to the left headlight, AFTER the fuse.

What happens if both fog lights go out?

(I have pulled the connections and colours out of the 2008 Mazda3 Wiring Manual, and triple checked the pins and colours… and if it were my car I would be out testing using this info… but if something fries, don’t blame me! ) what if both FOG lights went out????

How are the low beams on a Mazda3 connected?

The low beams only have two wires going to the bulb and neither of them have power. Unless the wiring diagram is lying, there are no connectors or fuses etc. of any sort between where the fogs relay wire splits off and the wire at the headlight. So I would double check what is showing up at the connectors.

Why are the headlights not working on my Mazda3?

Final possibility might be the headlight switch… you can check this by grounding pin AS on J-03 on the PJB. If the headlights go on when that pin is grounded then the issue is either the switch or the wires leading to it. J-03 is on the top (side with the fuses) of the PJB, and is the fat connector that is right beside the skinny connector.

What causes a low beam light to stop working?

If a headlight fuse blows, it could cause the headlights to stop working. Most headlight systems are also designed with a relay that switches the power between low beam and high beam headlights.

How many fuses are in front low beam light?

There are 2 10 Amp fuses, one for each front low beam light (#14 and 15 in the fuse box), so won´t expect for both to blow at the same time. There is however also a single lowbeam relay, which gets its signal from the body control module.

Where are the headlight relays on a Mazda3?

Both headlight relays are inside the PJB, and not accessible unless you disassemble the PJB. I don’t even know if they can be replaced… they are likely soldered to the circuit board. If the highbeams also do not work then, you should check the 40A fuse in the fuse box under the hood (F4).

If a headlight fuse blows, it could cause the headlights to stop working. Most headlight systems are also designed with a relay that switches the power between low beam and high beam headlights.

What causes a headlight to stop working in a car?

All the electrical systems in your car, including the headlights, are protected with fuses. These are designed to ‘blow’ and break the circuit if too much power comes through them. This protects all the components on the circuit. If a headlight fuse blows, it could cause the headlights to stop working.
