Blown fuses
 

i know this is a lame question so please bare with me.

so the fuse to my fan blew the other day causing my car to overheat, i pulled the fuse out of the heater to replace the fan so my car can run but now i need to buy the fuse for my heater so the ac can work. With that nonsense said ive been looking online to where to purchase the 40 fuse and have been unsucsessful on finding that particular one.
can this fuse be bought at any autozone? or do i have to go to mazda to order it?

Try Trussville Mazda. They have an online ordering section on their website and their prices are pretty good.
