The Highlight on My 323 protege 1990 SOHC 1800cc is not working (when push the lever away from the driver), but the momentanea highlight is ok (when pull the lever toward the driver) also the low light is OK. I need to know if it's the mechanical switch problem or maybe it's the electric headlight relay problem. If it's the relay then please let me know where is it located? I have look over the Chilton Mazda manual but can't find it.
