Update: Dealer replaced "Fan control module" and fan still on. 80 degrees here but temp gauge is normal just below half. Could someone asnswer for me what is normal running time for the cooling fan on a warm day? My understanding is the fan would only run when temp gets to high displayed on the temp gauge(at or above half). When I drove home from the dealer, the fan was on 50% of the commute. I take the car back tomorrow.
