Anybody with a Mazda 3?
I have an 05 Mazda 3 hatchback. This morning my low beams don't work. I have ruled out the bulbs because, both at the same time, really? I looked on the Mazda 3 forum a little and posed the question as to the location of the relay, but really the response time on there compared to here is turtle-like.

I had an 11, but I just sold it. This is from a Mazda forum:
Plenty of possibilities here: 1. Obviously, the switch could be suspected. I doubt it. Your headlights are controlled by one (or more) relays. The switch operates the relay(s). From the comments here, it sounds as if Mazda has placed separate control relays in each headlight fixture -- strange idea. If you have replaced your OE lamps with new lamps that draw significantly more current, then you could have damaged relay contacts. That doesn't sound like what is going on with your car. You may select replacement lamps that have different color outputs with the same wattage. 2. Loss of ground. I would say that this is a likely suspect. It should be easy enough to test for ground continuity with an ohmmeter, but you must first replicate the intermittent problem. If it is an intermittent ground loss, then it would probably show up as high resistance even when the light is working. There is a possibility that your headlight socket could have a good ground, but your control relay doesn't. Also a possibility that you have a corroded hot wire connection between your switch and relay coil. 3. Bad relay. This could be an intermittent fault with the relay coil or corroded contacts inside the control relay. If switching on and off fixes the problem, then that suggests bad relay contacts as the probable culprit. 4. Bad lamp is a remote possibility. As a rule, a lamp is either good or bad. However, it is possible for a lamp to have a broken filament that makes and breaks. This is a rare condition and the lamp wouldn't maintain this condition for long without failing completely. It would also tend to respond to vibration -- so you would likely see it blink while driving. Corrosion in the lamp socket is also a possibility.

To my knowledge the bulbs are original, but I have yet to check them. I will at lunch today. Both lights don't work on low. The high beams work fine.
Thanks for your input. From what forum does that originate?

you also have seperate fuses for left and right low and high operation, check fuses first...

Alright, I have good fuses, I have 14+ volts going through them relative to the switch being on and off. I have 14+ voldts at the plug going into the light and I get no continuity going through the bulbs. Now I come to find out some of these cars have xenon bulbs which means you wouldn't have any continuity through the bulb anyway, correct?
Alright, I have the halogen bulbs....which have no continuity.....which means they are dead.....BOTH of them? This is a first.
