Hello guys i really need some help, i would much appreciate it if someone can help me out in this situation. I have a 2006 chevy malibu 2.2L engine and the car was over heating because of bad water pump. So I changed the waterpump and it’s working rn. But after I install the waterpump, the car was still over heating and I found out that my cooling fan wasn’t working. So I diagnosed everything. (The fan motor, relays Fuses, cts,wires ) everything is working and when I unplug it from cts the fan would work because of the safety fail. But I don’t understand what’s going on and why it’s not working.

I’ve installed new water pump . New thermostat, and new cts . And something is not telling the computer to send electricity to the cooling fan relay . I’m not sure if the ecm has problem. But it’s either not getting signal or not working at all . Even if I connect the cts both wires the fan doesn’t turn on . And the wire is still getting 5v od electric.
