2002 Liberty fan relay location

I got a 2002 Jeep liberty with the 3.7 V6 and it seems to be overheating. I didn't hear the cooling fan on and it was almost to the red. I pulled over and let it cool a bit. I started driving again, and it started heating up again. Just before I pulled into my driveway I saw the temp going down. When I parked it I heard the cooling fan on. Does anyone know where the fan relay is ? I looked in the power distribution center and I did not see a relay for the fan there.

it is on the unibody frame rails, i believe on the drivers side by the power steering hoses. mike
