If it ain't broken don't fix it!
If your talking about the front fan at the radiator it comes on when the A/C is running, and your car gets the best gas milage when it's hot.

I think if you jumper the terminals like you would when you are reading codes it causes both fans to come on? Someone please confirm. If so, maybe the you can see if it doesn't work and why?

Basically, ground the fan relay through your toggle switch. If you know where the fan relay is.
