Your post is confusing, because I'm not sure exactly what testing you did.

Both fans cool the radiator and a/c condenser. The names are misleading.

The condenser fan has a hockey puck motor and is on the driver's side, the radiator fan has a longer motor and is on the passenger side.

ECT switch A on the thermostat housing will turn on both fans when the coolant reaches 199 °F when the engine is running. Start the car, unplug ECT-A, and jump the connector. Let us know which fan(s) run and don't.

ECT switch B is on the cylinder head and only turns on the radiator fan when the engine is over 223 °F and the engine is not running. Unplug ECT-B when the engine is off and key out of the ignition, jump the electrical connector with a piece of wire, and let us know if the radiator fan runs or not.

I found a broken connector on my control module/timer and my original one was burnt up. So I’m going to get another one and try again

Start at the fan relay. Unplug the relay. Two pins should be thicker and possibly better metal on the relay. On the fuse box pins. One of those 2 larger pins should have power. One of the two smaller ones should also have power.
