Check wires from ac pump. They must be shorting out somewhere. Or any other wires related to the AC. Or it could be the pump clutch itself is seized up.

88 toyota pick up v6 keeps blowing efi fuse


you may have a short of some kind, when a fuse blows repeatedly it is no good just replacing, you are being told that something is wrong with the equipment.
You will almost certainly have to visit a technician for a diagnosis. It is unlikely to be something that an inexperienced end user can sort out I am afraid.

GOOD LUCK

15amp efi fuse blows


It is not related to car being cool down , I think you are having ignition switch on . The EFI fuse goes directly to the contact switchin the EFI relay. Maybe try removing the EFI relay, turn the ignition to ON, and see if the fuse blows.
Doing this, the car won't start, but it might give you a clue as to where the short circuit is located. ... Check the fuse/relay box next to the driver side fender in the engine compartment.

Why does my efi fuse keeps popping 1999 chevy prizm


Pull the EFI relay, replace the fuse, and see if it blows when you turn the key on. If it does not turn the key off, reinstall the EFI relay and remove the circuit opening relay/fuel pump relay. Turn the key on. If the fuse blows than we know the problem is One of the O2 sensors, the IAC, the purge solenoid, or the ECM You can unplug the O2 sensors, iac, and purge solenoid. Replace the fuse, turn the key on, and plug them in one at a time until the fuse blows. Replace that component. If the fuse blows with those unplugged than its probaly the wiring and possibly the ECM. let me know what you find and I'll help you more if needed.
