Hello, Scotty, I have 2003 3.4L V6 Chevy Impala and I am really stumped why the radiator cooling fans are not coming on.

I have checked the relays & the fans actually work if you connect them to the battery. I also replaced the cooling fans temp switch.

I am thinking it a corroded wiring connector or ECM or BCM whichever of those that control this stuff

thanks any help or suggestions would be greatly appreciated
