Default Fan not working and plug looks mint

I never seem to hear the fan come on and in traffic I can be up to 220-230ish which seems hot. Checked the upper fan plug and it looks absolutely mint. What's the best process to tackle this?
Later today i am going to start the car and throw the AC on too, see if the fan comes on

Here's the wiring diagram for the cooling circuit.

You really need to pull the plug apart to validate the 3 connectors are in good shape on both ends of the receptacle. If your A/C system is fully charged and working, the fan should automatically come on with the A/C engaged.

Checked the fuse and appears to be ok, turning on the AC did nothing for the fan. Guess I’ll have to get the multi meter out

Although the plug internals are the usual problem, I've had one occasion where the fault was farther down toward the fan module itself. My first fix was a GM replacement connector. I don't suggest that, because the wire gauge is smaller (12 vs 10 IIRC) and it burnt itself up in about a year.

replacement connector now is actually smaller gauge than original?

i bought a large 3 wire connector used for car audio projects to connect them together. i know that’s not the suspected issue here though.
