Ok, if I had to guess, I would say you have a bad clutch.
Here is what is in the circuit one that Primary Fan Fuse 10 amp.
The Powertrain Control Module activates an internal switch to give a ground to your ac compressor relay coil. This allows power to flow from your fuse to the ac compressor clutch. Power does tap off after the relay to give a signal to the powertrain control module, and there is a diode 16mm up stream from the compressor clutch connecttor to prevent electrical spikes.
Lets say the powertrain control module is good, since it was not worked on when this problem started. That leaves the diode, clutch and relay as the problems. I doubt it is a wire problem if it pops at the 3 minute mark each time.
If you didnt accidentally removed the diode when changing the parts, I doubt it is the diode. Usually of they go bad, they stay bad. (Outside chance that it might heat up and fail)
This leaves me staring at the clutch. I know u said it wasnt dragging, but it is electrical, and if it is drawing too much current, it will pop a fuse. Check the plug real good and make sure there is no corrosion adding to the resistance. Also check the engine ground that gives the clutch a ground. If it is loose or corroded, it may cause extra current draw to pop a fuse.
Good luck on fixing this. And if I think of anything else I will post it.
