check for power and ground at the fan plug, relay, and fuse

When you say "cooling fan", do you mean the radiator fan or the cabin air fan? If the radiator fan and the compressor are failing to come on, it could just be low refrigerant but in either case there is no guarantee that any single component would cause what you describe. It could be a fuse, relay, controls, connector or any of a number of possible causes.
it is brokin
replace the fan motor
try picking up a new fan relay + check fuse and module fan behind bumper
Cooling fan is designed to come on when A/C,defroster, or engine temperature exceeds 235 degrees only
