The fan is controlled by the ECM.
Check the FAN fuse under the dash.
Next check the fan relay located in the engine compartment on the firewall, near the brake booster.
It’s the one on the left.
( Driver’s side for newbies. )
You can switch relays for testing.
You can apply 12 volts directly to the fan to see if it works.
The ECM turns on the fan about 220°.

If People Drove Any Slower They’d Be Going Backwards
When you see fog lights on in good weather beware. Low performance driver ahead.
How bout those nitwits too scared to drive without headlights in the daytime,
and the nitwits that need headlights for a little rain
