So I just bought a Mazda 3 grand touring with stock hid lights and they both were out when I got it. The high beams work. Replaced the hids and still not working. Checked all the fuses and they are fine. Don't know where to go from there. Thanks

 

It sounds like there's an issue with the assembly itself. Do the lights come on at all when it's just the lows?

 

What year is your Mazda 3 Grand Touring?
