Here is a thread I found while researching a similar problem. https://ls1tech.com/forums/stereo-el...ling-fans.html
Come to find out after searching and chasing wires, the car runs hot from the factory and you need to get the PCM redone in order to change the fan on temp setting or hard wire the fans. Good luck.
