Hey i was wondering if you knew how to fix the headlight of my miata one is up the other one is closed and when i turn on the headlights they switch

This is a useful wiring diagram. I would say try swapping the relays over first and see if Low Beams now work and High Beams don't.

Other possibilities are two failed bulbs, or a broken connector. A good test meter should be able to trace this.

It does appear to be a known issue

This suggests the combination switch

Hey dean how's it going ? here is video on how to do it ! It's not the same vehicle but should be close ! How To Install Replace Headlight Turn Signal Switch Honda Accord Prelude...

Common problem with any brand of car with power headlights. Probably the motor. You could inspect the unit to verify that it moves freely. Check on the Miata forum.

Check out "Headlight Fix for the 4th Generation Firebird/Trans Am" (http://www.bfranker.badz28.com/headlightfix/).

replace the high beam switch which causes this problem. Also clean the terminals for the directional light bulb. That will cause a negative continuity to the bulb

Sounds like both dim filaments are broken.
But before you go off and buy a new headlight, try removing the headlight and run a positive lead to each side of the hi and low connectors. Negative is the center pin, like this -_- if dim works with a battery, then you need to replace your dimmer switch. If not, its the headlight itself.

You knew the name of it, it's in your question, highbeam switch! Ahhh... the good old days... the highbeam switch was foot operated, remove 2 screws, unplug wire, that was all there was to fixing it.

I have a problem with my tail lights in my mazda. Brake lights working great but the light that supposed to be working during night time are not. By the way the front lights are working too! Also the light of the panel inside is not working. Can anyone please tell me how to fix it?
Thanks alot in advance!

what should i be getting for gas milage on a 1999 miata?

Notice how your headlights are protected under the hood by a suspiciously large rubber cover? Miatas hate humidity and condensation, from head to toe, including the headlights. I lost a headlight, was pulled over by a state trooper who told me to change it, and tested the brights all in one night. Of course, the brights worked, because they are actuated from a different circuit on the wiring harness that connects to the headlight through that massive rubber seal. If any amount of humidity or condensation has occurred, especially during a weather change, I cannot stress that enough, the first thing to fail is the normal headlight setting. I was already going to switch over to high-intensity bulbs, so I had a good excuse to crack open the headlight assembly (otherwise I wouldn't dare--Miata headlights are nearly impossible to change with a large pair of hands). I separated the old bulbs from their wires and proceeded to clean the connectors of the wires with an approved electrical connection cleaning solution (go to AutoZone). I then applied the conducting gel to the bulb to avoid corrosion and secure against future problems with condensation and was good to go. Make sure to give yourself many many hours to decipher the bulb assembly, as it was designed by someone whose sole intent is to make the job 150 times more difficult. Otherwise, cleaning the wiring assembly is a cinch.
