Reply to "A/C"

Try disconnecting the condenser fan wire at the fan. Turn the key on and turn on the A/C switch (engine off). Wait and see if the fuse blows.

If the fuse blows, then there is an issue with the wiring to the condenser fan. If the relays are mounted above the passenger foot well, look to see if the cover that covers all of the relays has pinched a wire.

If the fuse doesn't blow, then reconnect the condenser fan wire and try again. If the fuse blows, then the condenser fan is bad. If the fuse still doesn't blow, then turn on the blower motor and try again.

You could have the blower motor or a radiator cooling fan (or both) connected to the A/C fuse.

By doing these tests with the engine off, you won't be losing refrigerant.

You may want to connect a battery charger to the battery for these tests.

As has been suggested above, you should add at least a binary switch to the refrigerant system. This will turn off the compressor clutch if the pressure gets too high, or if the pressure is too low.
