Have a G2, and I know that a common problem is that the radiator fan switch can go on while the car is off, or it can stay on for a long period of time.

The car is cold, like below normal operating temp and i shut it off, but the fan will stay on, and then it will click on and off over and over again.

Where is the swithc located so that I can replace it?
Where can I get a replacement swithc?

Thanx.
