Electric radiator fan
My 05's electric fan turns on automatically when I start the car on a hot
day. The engine is not hot (just started from cold) and the temp gauge does not read high ever. Is there a way to adjust this so it only comes on when engine is hot?

When you start the car on hot days is the A/C on?
Sorry for delay, out of town for a few days. Yes, a/c is on, I leave on all the time. Does this make a difference? Fan does not come on with cooler days and a/c is on. Is there some adjustment dealer can make or is just the way it is? Thanks for your reply.
The fans are controlled by a separate fan control module that makes the fans run ONLY when its necessary for either AC operation or coolant temperature.
But they do NOT run at full speed. They are modulated between 10 and 90 percent to the demands of the PCM.
