Posted this on a facebook group but no luck yet.

I have an 05 Tahoe 5.3.

The e-fans for the radiator turn on as soon as I start the engine and run continuously until I shut off the vehicle. My A/C is off when I start it up but operates normally when turned on.

Coolant temperature sensor is good;

3 relays + fuses are good as well.

Thermostat is good

I don’t see any corrosion on any of the plugs, fuses, relays and all the wiring looks decent. (No bare wires that I see)

Anyone have any ideas what to look for next? I think I’m to the point where I’m going to have to have a professional look at it because I’m missing something somewhere.
