NA Miata Pop-Up Headlight Motors, Links & Relays

No clean supersession chain found for the motors; current Mazda dealer listings still use NA01-51-SBX and NA01-51-SAX. Relay split needs page copy: LA12-67-740 is commonly sold as 1990-93 retractor/headlight relay; 1994-97 listings show B481-67-7C0B for the retractor relay.

Gate 1 verified. 1990-1997 NA Miata pop-up motor numbers split by side: NA01-51-SBX left/driver, NA01-51-SAX right/passenger. Real trap: the motor is not always the failure. Relay/timer issues and cracked solder joints can cause intermittent pop-up/retract faults, and 1990-93 vs 1994-97 relay listings do not all use the same number. Public page should force diagnosis before buying a $300-400+ motor.

Checked genuine Mazda motor path at Mikes Miata Parts for side-specific NA01-51-SBX driver and NA01-51-SAX passenger motors. Checked 1990-1993 LA12-67-740 relay path separately. Both checked new paths were backordered; no new path is labeled in stock. Diagnose linkage, relay/timer and solder faults before buying a motor.

Driver and passenger motors are side-specific. The checked new motor and early relay paths were backordered. Diagnose linkage, relay/timer and cracked-solder faults before buying a motor. The 1994-1997 relay path remains year-specific and is not shown as live.
