So I just purchased a 2004 Cavalier, same issue. First checked fluid, it was low so I added coolant, next I checked fuses and relays and all are good, checked head gasket and it's fine, checked if thermostat was working and it is, checked for debris clogging the radiator and all is fine, then turned on the A/C to see if the fan would turn and found the fan is not turning/never turns on. Does anyone have how I could test the fan to see if it is just the fan versus a ground? I am still green and know the basics and this will be the first time dealing with this type of issue.
