Okay.
First off this is not a Mazda car but im guessing problem could happen to most cars.
Anyways
When i purchased the car about 5yrs ago my antenna doesn't go up or down and can't hear the motor working at all.
So it didn't bother for these years because reception was good but i thought i might as well fix it to make it functional.
So i brought a whole antenna assembly a while back and replaced it all and still nothing no noise from motor, i actually had 2 spares assembly so i tested the other one and still nothing.
So i thought i'd check the fuse (if there is one) and only one that says "radio" in the fuse box area but tested it and all good.
What could it be ? Could it be wiring issue ?
Because i have the same project car and also nothing as well, no noise. I was thinking wiring issue but surely 2 cars having the same problem doesn't sound right so makes me think maybe its something simple that i can't figure out ?
Here are the 2 fuse boxes diagram translated in this thread :

Unless its another fuse ? but i did check all fuses and all tested good.
