Is 250 Seat Wiring

[shoez]

Hey Guys!

I have recently bought two 2006 IS250 Seats that are, heated, cooled, and have electric movement. I am putting them into a different vehicle. We have the heated seats, and electric motors working, howver we are having trouble getting the seat cooler fan to switch on. We have even directed our 12.5v directly at the site of the motor and no luck. none of our wiring diagrams seem to indicate the fan there. Does anyone have any idea on how to get those fans to kick on!

Thank you in advance,
