One fan runs on low and the other on high with the AC on. Turn AC off, they should stop after a minute or less.

Both fans come on at high speed at 220F or something like that.

The AC trick is the best way to make sure that the fans are good.

Why would they come on at high speeds? when you're going fast, the air passes through the radiator quite easily. The one fan is meant to come on when the engine get to a certain temp so you don't overheat in stop and go traffic.

High speed of the FAN, not the car.

If you want to test to see if the fans work, turn on your air conditioning.

Install a fan override switch. A few of us are running them now.
