No. The fan should shut off when the engine temp is to cold for the fan to be on. If its on all the time the temperature switch/sensor is probably defective.
It can be very simple to remove the radiator from a Honda Civic. The first step is to drain the coolant from the radiator. The next step is to disconnect the cooling fan switch and remove the hoses. Then the cooling fan should be removed. Then the radiator should be unbolted and lifted carefully from the vehicle.
No
Cooling fan not working, or your cooling system needs a complete service. The cooling fan should be on continuously when the A/C is on.

By fans, I assume it has more than one. One of these fans will run continuously when the A/C is on. The other fan should only run when needed to cool the engine down. In stop and go city driving in the summer with the A/C on, both fans may very well run continuously. At highway speeds, only the A/C fan should normally run. Sounds like you need to have your cooling system serviced. A complete drain and flush of the cooling system and a replacement of the thermostat may help. Also make sure the radiator external fins are clean and not clogged with bugs and debris.
If you take the grill off of the front of the vehicle you should be able to see the radiator. Look on the passenger side of the radiator, your wing nut type plug should be on the side of the radiator. The Jeep Cherokee radiator drain plug is plastic and very fragile. You should remove the lower radiator hose to drain the cooling system.
The cooling system bleed valve, on your General Motors 5.7 liter engine, is located on the bottom of the radiator. The bleed valve should be in the middle of the radiator bottom.
There should be 15-17 psi in the cooling system when warmed up under normal operation. Any more than that the radiator cap should release.
Entire cooling system should be flushed to remove dirt, scale, rust and sediment buildup which will corrode and clog/ruin your engine/cooling system
You should have pressure in the cooling system. The radiator cap is marked as to how much pressure it is designed to hold, usually 15 to 17 lbs.
That one should run anytime the a/c is turned on.
Cooling fans? should be behind the radiator Heater fan - should be against firewall on passenger side
