Could be a few things...

I have the same vehicle and had the same problem. It could be 1 of 3 things.

1) Refrigerent low

2) Bad coolant level sensor



3) Aux. Fan Resistor, failing or has a rusted connection



4) Bad Coolant Temperature Sensor (picture borrowed from JimF's site :-) It's the blue one in the middle.



Check out the following interesting links:

Auxillery Fan Problem

and

When you disconnect the coolant Temp sensor, do the fans go on? If I remember correctly, they should if your relay is good.

A new relay is around $25 and a temp sensor is also cheap. Get them both here.
