2015 kia optima EX-L
So have a issue with my Kia Optima 2015. When car is setting in drive way and it is normal temp.. say getting in the morning to go to work... When I turn on my AC wide open... I noticed my radiator fan does not turn on and it blows warm air while idle. When I back it out of the driveway and start driving it starts cooling.. I get out and check and the Fan is now turning like it should... I took it to Kia dealership.. and they told me the Fan is supposed to turn on as soon as the Air conditioner button is engaged... They said I had a bad Fan and wanted to charge me $732 to replace the Fan Assembly and control module. I found it hard to believe it was the fan..and I know how easy it is to replace fan assembly. So I bought new Fan Assembly and module myself for under $200 and it didnt take 15 minutes to put in... I am glad that I did it and saved myself $500 bucks.. However it still has same symptoms so the Dealer Ship was a pure rip off.. They Charged me $120 and swore it was a bad fan. So now I have a new Fan Assembly and module and still same problem.... Quesion is the Fan supposed to turn on as soon as the Air Conditioner button is engaged? And if so what else would cause it not to turn on but turns on once engine gets warmed up?
