Hi Guys
I need some help understanding this circuit. By the looks of it, its a simple relay driver with a timer. But for some reason the actual relay does not work when power is applied to the appropriate pins.
This is from a wiring diagram of a Mazda Protege car. The timer is used (i believe) to time the amount of power given to the door lock motors and to reverse their polarity depending on the lock/unlock action.
