Cooling fan issue

Good evening. I've got an 2004 GTP. Recently the cooling fans stopped working based on engine temperature. They still work when the AC is on. We've circuit traced all the wiring and relays, and narrowed it down to the PCM not calling for fans. Is there a good retrofit option for cooling fans, or is a new PCM my only option?
 


Is it overheating? I'm just wondering if its a possibility your engine temp isn't getting hot enough for the PCM to kick the fans on.

ZZPerformance sells the Casper's hi-lo fan switch which lets you manually override the engine fans. It meant more for the guys that run at the track and want to cool down between runs. You just gotta remember to turn it off or you'll drain the battery
