Why does my Aux Fan spin when i Turn on climate control?

My car just started doing this. The Secondary fan will spin as soon as I turn on my digi climate control and will stop as soon as I turn it off. It has never done this before. I know its getting hot in my area, but even when the car is in a cool garage it will do this. any ideas? :help



thanks

Does the fan cycle on and off or just run the whole time until you shut off the a/c? Does it also go on with heat, and just plain forced air?

The secondary fan usually comes on whenever the A/C compressor comes on to aid in air flow accross the condenser core. (Regardless of engine temp)

it comes on as soon as i turn on the climate control and turns off as soon as i turn it off. it doesn't cycle.

it comes on as soon as i turn on the climate control and turns off as soon as i turn it off. it doesn't cycle.

yeah but be clear as to what you mean by turn on the "climate control." do you mean just turning on the fan? or do you mean turinng on the AIR CONDITIONER?
