The coolant fan on my 2011 Cruze will not turn on when it reaches running temperature. It does however turn on if I turn on the AC in my car. I have replaced the fuses, the relay switches, and the thermostat. I am at a loss here, and so completely frustrated with trying to troubleshoot this, that I feel like throwing the towel in. But I need this car to do basic things that life requires. If anyone can help me, I would greatly appreciate any help/ advice you can offer. Thank you so much for your help.

 

Does it overheat once it hits operating temp?
