I believe it is integrated with the light switch, so you need to replace the entire switch.
turn the headlight knob to bright
the fuse panel on the driver side, there is a fuse in the top left coner for that its a 10 amp check that, if its not that then it could be the headlight button
Alas you have a broken wire between the headlight switch and the fuse panel . pull the headlight out and check the wire connector,possibly add a jumper from another powered up circuit there.
There could be many reasons, but the first thing I would check is ARE BOTH HEADLIGHT STILL WORKING. As a tech I was once faked out till I found out there were 2 burned out headlights. Not always visibly dark bulbs.
If the headlights on your 1991 Mazda Miata won't go up or down, it could be due to a blown fuse, a malfunctioning headlight motor, or a wiring issue. First, check the fuse box for any blown fuses related to the headlights. If the fuse is fine, inspect the headlight motors and their connections for any signs of damage or corrosion. Additionally, ensure the headlight switch is functioning properly, as a faulty switch may prevent the headlights from operating.
You need a new battery!
