one highbeam wont work
 

I just had Both replaced, i guess the driver side highbeam still wont work?
Any suggestions?

you replaced them or someone else did? If someone touched the bulbs with their hands, the oil from your skin could cause it to fail prematurely.

Have you checked to see if it's plugged in properly?

Use rubbing alcohol and a cotton ball to clean the glass after replacement.

well it went out, then i took it in today to get my oil changed or the really big 48K mazda service one,
So since its -20 out i figured id just have them replace it, they did.. still doesnt work.
I decided i didnt want to spend the extra money at this moment to see what the problem is, seeing as how i dont drive it much during the winter to begin with, and i would check on here to see if anyone had some solutions before i drop money for them to just look at it.
