Correct fuse

If I'm reading this right, the terminals represented by #3 take a 15A fuse for heat only, but for A/C it takes a 25A fuse. Correct or?

Thanks

The "heater only" fan motor is less powerful and requires only a 15 amp fuse.. If the vehicle is equipped with AC, the correct fuse is 25 amp.
