Hello my name is ***** ***** thank you for your question.

Are the fans on all the time? Do you have the AC on when it does this?

My first fan will turn on 10 minutes after driving the car, then the second one comes on full blast

With ac or no ac on

Car will be at normal temp

Do you have the inside air controller on at all when the fans come on? Are these after market fans?

Customer: replied 5 months ago.
What do you mean the inside air controller and no everything stock
Expert:  Jay replied 5 months ago.

I mean the controller for the air system inside the car. Is that on what so ever?

Customer: replied 5 months ago.
I'm not understanding that, the ac?
Customer: replied 5 months ago.
Where can I find it
Expert:  Jay replied 5 months ago.

When you are sitting inside the car, the air controller above the radio. Is that ON what so ever? Doesn't have to be the AC. Just On and operating the air.

Customer: replied 5 months ago.
I believe so, I feel the air coming out when driving
Expert:  Jay replied 5 months ago.

Try turning off that controller and see if the fans turn off. Your car has Auto Air. So if that air controller is on what so ever, it will turn on the engine fans.

Give that a try and let me know.

I'm not around the car right now and my phones about to die, I just wanted to know if maybe it's the fan sensor and where could I buy one
Expert:  Jay replied 5 months ago.

These fans have there own control module. I would check to see if the fans turn off when the air is off. If it does, then that is normal for the fans to come on when the Air is turned on inside the car.

Other wise it could be that fan control amp.

Do you have any more questions on this?
