Trying to figure out why my ac and fan motor isn’t kicking on

Fuse 10 has power but fuse 20 does not. Pulling fuse 10 kicks on power to fuse 20. (Fan will kick on instantly when it is pulled and the ac gauge will light up) I can run the car like this but now my speedo won’t work because of fuse 10

While fuse 10 is in I have no power to windows, ac and fan switches, side Mirrors

Also putting fuse 10 in just stops the current to fuse 20 but does not blow any fuses.


Ac compressor always has power
I’ve even tried swapping my top ground on starter to bottom with no luck
I’ve ran through most of my dash wiring and engine wiring and can not pin point and bad wiring

Stuck on this and need some insight !
