Might possibly have a bad thermostat? First, do this.. Turn the car on, let it run for a second, and then double check to see if the fans are still not running. If they aren't, then turn the A/C on, and check again to see if they kicked on. If they did kick on, then there's your problem right there, the thermostat. Electric cooling fans are thermostatically controlled and engage whenever the air conditioning is turned on or when a probe mounted to the radiator reaches a specified temperature (195* in your case). Since you pretty much checked everything else, that would be my last guess. You can get a Jet performance 180*, or a Hypertech 160* thermostat for $16 at the link below. Which both are alot better than the stock one which is 195* (so the fans will kick on sooner):

If the A/C does not turn the fan on, then I would say that the ECM is your problem. And I'll tell ya what, if the above solution doesn't work, then I can hook you up with a deal. I just so happen to have a used ECM sitting in my garage from the 2nd 3.4L engine I bought. From what I was told, it is in perfect running condition. Actually, I can just swap it out with mine and double check to make sure. I'll sell it to you for $15 + s&h. And if it doesn't solve your problem, then you can just send it back and I'll refund your money. It's a win-win situation. Especially since ECM's can range from $40+ on eBay and some sites. Just let me know if your interested.
