Have Toyota Questions? Ask a Mechanic for Answers ASAP
A few things here:
First the "NAPA" parts equals BAD IDEA! I thought you were trying to actually fix the car?????
Second- the INTEGRATION relay is the only relay in this circuit other then the power relay and if the power relay was out then you would have other obvious issues with the car sir. . The 25 amp DOOR fuse, 10 amp GAUGE fuse and 30 amp POWER fuses are the only fuses that power this circuit. if yo have fuse power and no power to the system then replace the integration relay FROM THE DEALER.
